While it is impressive and I like to follow the advancements in this field, it is incredibly frustrating to listen to. I can't put my finger on why exactly. It's definitely closer to human-sounding, but the uncanny valley is so deep here that I find myself thinking "I just want the point, not the fake personality that is coming with it". I can't make it through a 30s demo.

We're used to hearing some kind of identity behind voices -- we unconsciously sense clusters of vocabulary, intonation patterns, ticks, frequent interruption vs quiet patience, silence tolerance, response patterns to various triggers, etc that communicate a coherent person of some kind.

We may not know that a given speaker is a GenX Methodist from Wisconsin that grew up at skate parks in the suburbs, but we hear clusters of speech behavior that lets our brain go "yeah, I'm used to things fitting together in this way sometimes"

These don't have that.

Instead, they seem to mostly smudge together behaviors that are just generally common in aggregate across the training data. The speakers all voice interrupting acknowledgements eagerly, they all use bright and enunciated podcaster tone, they all draw on similar word choice, etc -- they distinguish gender and each have a stable overall vocal tone, but no identity.

I don't doubt that this'll improve quickly though, by training specific "AI celebrity" voices narrowed to sound more coherent, natural, identifiable, and consistent. (And then, probably, leasing out those voices for $$$.)

As a tech demo for "render some vague sense of life behind this generated dialog" this is pretty good, though.

To be fair, the majority of podcasts are from a group of generic white guys, and they almost sound identical to these AI generated ones. The AI actually seems to to do a better job too.

Citation absolutely needed. You call this fair?

> the majority of podcasts are from a group of generic white guys

https://podcastcharts.byspotify.com/ keep the Pareto distribution in mind

I did the best fast research I could given not wanting to spend more than 20 minutes on it and came to this result (aprox): - Mixed/Diverse: 48.0% - White Men: 35.0% - Women: 8.0% - Non-White: 6.0% - White Woman: 2.0% - Non-White Woman: 1.0%

I love the "white = generic = bland" meme too. All the science and literature before 1930 it was trained on is also likely "generic white guys".

I laughed and sort of agreed with this, in spirit. You're off on the details I think though.

When I listened to the audio samples before coming to the comments, I thought: "oh, like those totally lifeless and bland U.S. accents from podcasts, YT, etc."

I wouldn't associate it with skin colour or gender though at all. I've no idea why you'd go there - any skin colour and any gender is absolutely welcomed into the fold of U.S. cultural production, if they can produce bland generic "content" sincerely enough, it seems to me.

Disclaimer: many U.S. accents are interesting and wonderful (Colorado; Tom Waits), they don't all sound generic and bland. I have U.S. friends therefore I can pass judgment (TM).

Whether this stops at the uncanny valley or progresses to specific "AI celebrity" voices, I'm left thinking the engineers involved in this never stopped to think carefully about whether this ought to be done in the first place.

"Surely my genAI product won't be used to spam zero-effort slop all over the internet!"

- guy whose genAI product will definitely be used to spam zero-effort slop all over the internet.

I think their main target is corporate creative jobs. Background music to ads/videos/etc. And just like with all AI, they will eat the jobs that support the rest of the system, making it a one and done. It will give a one time boost, and then be stuck at that level because creatives won't have the jobs that allowed them to add to the domain. In this case new music styles. New techniques. It's literally eating the seed corn where the sprouts are the creatives working in the boring commercial jobs that allow them to practice/become experts in the tools/etc that they then build up it all. Their goal is cut the jobs that create their training data and the ecosystem that builds up/expands the domain. Everywhere AI touches will basically be 'stuck using Cobol' because AI will be frozen at the point in time where the energy infusing 'sprouts' all had their jobs replaced by AI and without them creating new output for AI to train on it's all ossified.

We are witnessing in real time the answer to why 'The Matrix' was set when it was. Once AI takes over there is no future culture.

Assuming you are right and that we will miss a generation of creatives and AI keeps making crap, why can't the creative field regrow. AI won't remove creativity from human genes.

As people get fed up with AI generated crap, companies will start to pay very good money to the few remaining good human creatives in order to differentiate themselves. The field will then be seen as desirable, people will start working hard for to get these jobs, companies will take apprentices hoping they will become masters later, etc... We may lose a generation, but certainly not the entire future.

Of course, it is just one of many possible futures, but I think the most likely if you take your assumptions as a postulate. It may turn out that AIs end up not displacing creative jobs too much, or going the other way, that AIs end up being truly creative, building their own culture together with humans, or not.

It makes sense to me.

Step 0. Some People make novel art like a jingle that is unlike anything yet.

Step 1. Early use of said jingle creates a buzz and generated good sales results.

Step 2. It gets copied everywhere and by everyone. It is now a meme.

This is the step I think where generative AI can help. Slightly transform existing art to fit a particular purpose. This lets businesses save money by not paying humans do this work.

Problem is we don't know where the next person or when this step 0 comes from... When we soak up all the "slack" and send all the "money" to the top because lets face it that's how it will work. The money "saved" from AI won't make goods and services cheaper by any significant measure. We will still have to pay as much as we can afford to pay.

> It's literally eating the seed corn where the sprouts are the creatives working in the boring commercial jobs that allow them to practice/become experts in the tools/etc that they then build up it all.

This is a big problem that needs to be talked about more, the endgoal of AI seems to be quite grim for jobs and generally for humans. Where will this pure profit lead to? If all advertising will be generated who will want to have anything to do with all the products they’re advertising?

Reminds me of that famous clip from mad men where don suddenly realizes that if lucky strike can't say its cigarettes are safe, neither can its competitors and came up with "it's toasted".

In general, I have a feeling double digit growth forever is impossible. Facebook and Google both reported YoY growth in 15%+ this week iirc and I have a feeling they are only able to achieve this by destroying either competitors or adjacent industries rather than by "making the pie bigger". It will end at some point.

this is very spot on. There are tons of artists who have a job so they can sustain their own personal creativity.

Almost everyone has a job to sustain their actual interests. Some of them happen to be musicians, writers, etc. Others play football, go fishing, talk to friends. There is nothing special in there. All of us will keep doing what we like to do even after AIs become the tool of mainstream creativity.

Yes but many people have jobs in their fields, which benefits their personal and/or public creative endeavours.

I’ve learnt things and been exposed to ideas developing software for work that I simply wouldn’t have if I was only doing it in my spare time.

A meme parrot is posting the millionth copy of the same comment complaining about "slop". Slightly ironic.

It's the holy grail. When people can have naturalistic conversations with their computers they will love it more than other people. Ai doesn't need to be useful so much as it needs to be loved. That's the secret to getting AI between people and everything they do in a day.

Agreed. To me it sounds like bad voice-over actors reading from a script. So the natural parts of a conversation where you might say the wrong thing and step back to correct yourself are all gone. Impressive for sure.

Yup. Plus the interactions you'd expect for instance in terms of matching style of voice in a normal discussion are missing. That being said it still sounds pretty impressive.

every step of technological advancement builds on top of the previous one.

now it's bad voice actors, in 2 years it'll be great ones

This is why voice actors are on strike to stop their voices from being used with AI. I mean it's probably futile.

it's probably futile, and the 'AI/art protests' seem to miss the point that the protest itself is also encouraging The Man to seriously consider AI-powered replacement.

The protest itself is exactly the kind of thing that will be avoided by replacing humans, demonstrated writ-large for the people with the cheque-book.

I can understand the spirit of protest and why it occurs, but it just seems so out-of-line strategically/tactically when used against automation that's taking jobs.

Just the order of events is kind of funny to me, and this applies to automation-job-taking protest the world over : A technique is demonstrated that displaces workers, the workers then picket and refuse to work -- understandable, but faced with the current prospect of "This mechanism performs similar work for cheaper", it seems counter-productive to then demonstrate the worst-case-scenario for the patron : a work stoppage that an automated workforce would never experience, alongside legal fees that would never be encountered had they an automated work-force.

That all said, protest is one of the only weapons in the arsenal of the working -- it just feels as if the argument against automation is one of the places where that technique rings hollow.

In the case of media/movies/literature/etc, I think the power to force corporations to value humans is solely in the hands of the consumer -- and unfortunately that's such an unorganized 'group' that it's unlikely they will establish any kind of collective action that would instantiate change.

Totally agree. Maybe it’s just the clips they chose, but it feels overfit on the weird conversational elements that make it impressive? Like the “oh yeahs” from the other person when someone is speaking. It is cool to see that natural flow in a conversation generated by a model, but there’s waaaay too much of it in these examples to sound natural.

And I say all that completely slackjawed that this is possible.

I love the technology, but I really don't want AI to sound like this.

Imagine being stuck on a call with this.

> "Hey, so like, is there anything I can help you with today?"

> "Talk to a person."

> "Oh wow, right. (chuckle) You got it. Well, before I connect you, can you maybe tell me a little bit more about what problem you're having? For example, maybe it's something to do with..."

That's how the DJ feature of Spotify talks and it's pretty jarring.

"How's it going. We're gonna start by taking you back to your 2022 favorites, starting with the sweet sounds of XYZ". There's very little you can tweak about it, the suggestions kinda suck, but you're getting a fake friend to introduce them to you. Yay, I guess..

Reminds me of the robots from the Sirius cybernetics corporation. “Your plastic pal who’s fun to be with.”

I'd love to see stats on disfluency rate in conversation, podcasts, and this sample to get an idea of where it lies. It seems like they could have cranked it up, but there's also the chance that it's just the frequency illusion because we were primed to pay attention to it.

> Like the “oh yeahs” from the other person when someone is speaking.

I bet that if you select a British accent you will get fewer of them.

I'm hoping it will be a lot of Ok Guv'ner and right you ares in the style of Dick Van Dyke.

Gor blimey lad, that's the problem now innit???

> a British accent

Hmm.... Scottish, Welsh, Irish (Nor'n) or English? If English, North or South? If North, which city? Brummie? Scouse? If South, London? Cockney or Multicultural London English [0]?

[0] https://en.wikipedia.org/wiki/Multicultural_London_English

Need to increase your granularity a bit. I live in Wexford Town, Ireland, and the other day I was chatting to a person that told me their old schoolmates from Castlebridge are making fun of their accent changing since moving from their hometown.

Castlebridge is 10 minutes away by car. Madness!

Yeah, totally agree. Here's a useful link for non-Brits, that goes into a bit more detail:

https://accentbiasbritain.org/accents-in-britain/

Also, we have yet to define precisely define what is meant by 'British'. This probably needs a "20 falsehoods people believe about..."-type article.

When people outside the British isles (esp. Americans) say "British accent", they almost invariably mean (British) English, and usually the "received pronunciation" accent that British media generally uses.

They do not mean Irish or Scottish accents; if they did, they would have said exactly that, because those accents are quite different from standard (British) English accents. So different, in fact, that even Americans can readily tell the difference, when they frequently have some trouble telling English and Australian accents apart.

Also, to most English speakers, "English accent" doesn't make much sense, because "English" is the language. It sounds like saying a German speaker, speaking German, has a "German accent". Saying "British accent" differentiates the language (English, spoken by people worldwide) from the accent (which refers to one part of one country that uses that language).

Right mate

Cheeky bugger, you are

ee by gum

It's like their training set was made up entirely of awkward podcaster banter.

At least 83% Leo Laporte.

If I turn the volume down to the point that I only hear the cadence/rhythm of the voices, but can no longer make out the words, it sounds like any, “This Week in…” podcast.

For me it isn’t uncanny from a lack of humanity. Rather, it triggers all my “fake and shallow” personality biases. It certainly sounds human enough, just not the type of humans I like.

Agreed. To be fair, I also get annoyed by fake/exaggerated expression from human podcasters.

That could just be the context though. Listening to a clip that's a demo of what the model can produce is very different to listening to a YouTube video that's using the model to generate speech about something you'd actually want to watch a video of.

It sounds like every sentence is an ad read.

Yeah... It isn't that it doesn't sound like human speech... it just sounds like how humans speak when they are uncomfortable or reading prepared and they aren't good at it.

Probably because you're expecting it and looking at a demo page. Put these voices behind a real video or advertisement and I would imagine most people wouldn't be able to tell that it's AI generated at all.

It'd be annoying to me whether it was AI or human. The faux-excitement and pseudo-bonhomie is grating. They should focus on how people actually talk, not on copying the vocal intonation of coked-up public radio presenters just back from a positive affirmation seminar.

I suppose it doesn't matter if it is a human, or a bot delivering the message, if the message is boring

I agree. It’s profoundly sad that so much energy is being invested in solving the non-problem of making long documents accessible. To think that people will ignore carefully written work for the “chat show” output of an LLM is horrifying and a harbinger of a societal slide into happy stupidity and willing ignorance.

> Example of a multi-speaker dialogue generated by NotebookLM Audio Overview, based on a few potato-related documents.

Listening to this on 1.75x speed is excellent. I think the generated speaking speed is slow for audio quality, bc it'd be much harder to slow-down the generated audio while retaining quality than vice versa.

It's due to the histrionic mental epidemic that we are going through.

A lot of people are just like that IRL.

They cannot just say "the food was fine", it's usually some crap like "What on earth! These are the best cheese sticks I've had IN MY EN TI R E LIFE!".

“I’m OBSESSED with the dipping sauce. So good.”

I tuned it out instantly because I have that feeling with most Americans / podcasts / etc already. That said, it's a convincing enough analog for that kind of content I think.

It doesn't feel any different to me than listening to a random radio station where I don't know who is speaking. I didn't feel any uncanny valley but I'm not an English native speaker so I might miss some nuances. However there are relatively few English native speakers around the world so this might not be a problem for us.

The problem is that people talking over each other is not a format I long to listen to.

While it is impressive and I like to follow the advancements in this field...

Please don't think that I'm trying to suggest... anything . It's just that I'm getting used to read this pattern in the output of LLMs. "While this and that is great...". Maybe we're mimicking them now? I catch myself using these disclaimers even in spoken language.

I like to preface negativity with a positive note. Maybe I am influenced in my word choice but my intent was to point out that this is a very, very impressive feat and I don't want to undermine it.

Whilst I don't doubt you feel like that the general response to the notebook LLM podcast feature (which uses this) has been very well received generally.

In general people find the back and forth between the "hosts" engaging and also gives people time to digest the contents.

When I got to the bit where they referred to the smaller training set of paid voice actors, that hit it for me. It certainly sounds like they are throwing the 'um' and 'ah's in to a script - not naturally.

This is good, but certainly not yet great.

There’s a certain fakeness to the rhythm of the space between words. Particularly the “uh” and “um” filler sounds. To me it sounds like they always either come in abnormally early or late after speaking those sounds

It's because it's probably trained with "professional audio", ads, movies, audiobooks, and not "normal people talking". Like the effect when diffusion was mostly trained with stock photos.

they all sound like valley-people, complete with the raspy voice and everything

> Audio clip of two speakers telling a funny story, with laughter at the punchline.

In similar vein, I’m glad they told me it was a funny story, because otherwise I wouldn’t have known.

I got a similar feeling. I think it was overdoing the ums and uhhs for something trying to sound like an even slightly professional podcast kind of sound.

I get the feeling that this is useful for something that someone half-listens to.

Try it out in the demo https://cloud.google.com/text-to-speech/?hl=en and in the API https://cloud.google.com/text-to-speech/docs/create-dialogue...

If I change the language in the demo, it removes all my text and replaces it with a template text. That's bad.

I think I put my finger on exactly why it sounds a bit uncanny-valley: it sounds like humans who are reading from a prepared 'bit' or 'script'.

We've all been on those webinars where it's clear -- despite the infusions (on cue) of "enthusiasm" from the speaker attempting to make it sound more natural and off-the-cuff -- that they are reading from a script.

It's a difficult-to-mask phenomenon for humans.

That all said, I actually have more grace for an AI sounding like this than I do for a human presenter reading from a script. Like, if I'm here "live" and paying attention to what you're saying, at least do me the service of truly being "here" with me and authentically communicating vs. simply reading something.

If you're going to simply read something, then just send it to me to read too - don't pretend it's a spontaneously synchronous communication.

But what's the end goal and audience here? I don't believe people will resonate with robots making "um" and "ohs" because people usually resonate with an artist, a producer, a writer, a singer etc. A human layer with which people can empathize is essential. This can work as long as people are deceived and don't know there is no human behind it. If however i find out that a video is AI -generated i instantly lose interest in it. There are e.g. a lot of AI-generated architecture videos on youtube at the moment, i have never wanted to listen to one, because i know the emotions will be fake.

> I don't believe people will resonate with robots making "um" and "ohs" because people usually resonate with an artist, a producer, a writer, a singer etc.

I think they absolutely will, because "resonating" is not a material phenomenon, it's something people decide that they're doing. Your connection with an actor on television is not an actual connection. Most of acting is learning the times and length to be silent while making a particular face (dictated by the director) in order for the audience to project feelings and thoughts onto you. You're thinking about your camera blocking, or your groceries, and your audience sees you thinking about some plot point in a fictional world.

I've got a theory that we severely damaged a generation of girls by inundating them with images of girls their own age singing songs and acting parts all written and directed by middle-aged men - ones who chose as a profession to write songs in the voices of, write fiction in the voices of, and to direct, photograph and choreograph in person, tween girls. Their models of themselves have come from looking at these depictions of girls, who were never allowed to speak for themselves, and resonating.

> what's the end goal and audience here?

1. Voice acting for low-budget/no-budget animations and games.

2. Billions of youtube "top 50 building demolitions" where the forgettable presentation is narrated by forgettable AI. Now we'll get "podcast style" conversation narration over those videos. Instead of bailing after 30 sec with regret, you might make a whole minute.

3. Reaction videos? Sometimes I weaken. I want to see a random person's reaction to their "first time listening" to the famous song they somehow have never heard until this moment. If we humans lower ourselves to reaction videos, we'll watch/listen to AI chatting to itself about things we love. Once the content gets "spicy", beyond the potato salad google demos, the floodgates will open. God help us.

It’s amazing for reading articles

It looks like lately a lot of progress have been made in audio generation / audio understanding (everything related to speech, I mean).

Is this related to LLM, or is this a completely different branch of AI, and is it just a coincidence? I am curious.

It's very related to LLMs. Though instead of text tokens you are working with audio tokens (e.g. from SoundStream). Then you go to audio corpus, instead of text corpus.

Is there a free (ad supported?) online tool without login that reads text that you paste into it?

I often would like to listen to a blog post instead of reading it, but haven't found an easy, quick solution yet.

I tried piping text through OpenAI's tts-1-hd, model and it is the first one I ever found that is human like enough for me to like listening to it. So I could write a tool for my own usecase that pipes the text to tts-1-hd and plays the audio. But maybe there is already something with a public web interface out there?

Both windows and macos (the operating systems) have this built-in under accessibility. It’s worth a try and I use it sometimes when I want to read something while cooking.

I use ms edge for this exact use case. Works well enough on any platform

Yup, I second this. The only thing I use Edge for.

I did a bit of research and it seems to be, by far, the highest-quality TTS engine that is free and you can do things like pause and continue.

There are other options that have higher-quality voices, but they aren't free.

I use the wavenet extension and use my 1M character free quota from Google cloud

There is on iOS. No ads. "Reader" by Eleven Labs. I haven't used it that much but have listened to some white papers and blogs (some of which were like 45 minutes) and it "just worked". Even let's you click text you want to jump to.

And it's Eleven Labs quality- which unless I've fallen behind the times is the highest quality TTS by a margin.

There's also the built-in "Speak Selection" feature you can enable in the accessibility settings.

Reader is on a pretty good path to a monthly subscription model. Great audio quality, large selection of voices, and support for long-form input text.

firefox does this directly. Reader mode has a headphones symbol to read webpage text.

Good old Microsoft Sam? It'll sound like Stephen Hawking is reading it to you!

The voices are impressive (I can't tell the difference as a non native speaker) but their "personality" sounds extremely annoying lmao

I know. Can they do anything other than obnoxious Californian? The vocal fry is off the charts.

We've been using this at work to get inside of our customer's perspective. It's helpful to throw eg a bunch of point-of-sale data sync challenges into Notebook LM and eg pass a 10 minute audio to the team so they can understand where our work fits in.

I’ve cut and pasted weeks of Slack conversations into NotebookLM and it was quite entertaining to then listen to a Podcast talking humorously about all the arguments in the #management channel.

For someone who has never used NotebookLM, how would I get started doing this?

Go to https://notebooklm.google and log in with a Google account. Then just paste whatever text or files you want to chat about. That’s basically it.

ah.. so "frontier" is the new buzzword that keeps the corporate board invested in this dead end?

frontier garbage.

> This means it generates audio over 40-times faster than real time.

Astounding

To paraphrase the great Bertram Gilfoyle, computers don't need to produce fake vocal tics.

This is a "holy shit" moment for me, and I consider myself fairly jaded. If you listen closely you can tell it's a little off, but about halfway through I could clearly feel my brain click into a different mode where it believed what it was hearing was real.

YouTube videos are already infested with insufferable AI elevator background "music". Even some channels that were previously good are using it.

On the bright side, you can stop watching these channels and have more time for serious things.

> AI elevator background "music".

What are some examples? I haven't encountered this.

Just search 'jazz' on YouTube.

Almost all of the results will not consist of 'jazz' in any real sense, but instead a collection of uncanny melodies and chord progressions that wonder around going nowhere, traditionally accompanied by an obscenely eye-offending diffusion model-generated mishmash of seasonal tropes and incongruent interior design choices. Often, it's MIDI bossa nova presumably written by either a machine or someone who's only ever heard a few bars of music at a time and has no idea that 'feel' or 'soul' are a thing.

Can you post a link to some like that?

Because when I search "jazz" on YT I'm just getting legit music videos and jazz playlists -- stuff like Norah Jones, top 100 jazz classics playlists, etc.

But I assume that search results are personalized.

Lucky you!

Sure. I just tried in private browsing mode, and got mostly the same. Here are a few of the very first results I get for 'jazz':

https://www.youtube.com/watch?v=xhL3Cb740VY

https://www.youtube.com/watch?v=ABmQvH5K75w

https://www.youtube.com/watch?v=-jgEswq9ZlI

Some are worse than others.

That's wild. Thanks for the links. Infinite AI Muzak I guess? I suppose it was inevitable.

Seems to be genuinely popular. I can see why, but when there's so much 'real music' out there, why not just listen to that and enrich yourself instead of bathing in fake nonsense? If you want jazz, just put on a jazz album — hell, even Kind of Blue will do.

I'm not sure all (or any) of it actually is AI though. I assume that's coming very soon, but I suspect this stuff is cynically and methodically hand-composed.

By the way: I have nothing against generative composition! Brian Eno has been doing this stuff longer than anyone else, and it's very cool. I'm sure you could make some 'generative jazz' that's actually distinctive and artistic, but this isn't it.

Not longer than Steve Reich, John Cage, Philip Glass, or Ann Southam.

Nor for that matter Mozart, who wrote simple algorithmic compositions powered by dice. These were common musical games in his day.

You’re probably right, but I meant generative in the sense of building a machine that does the entire process.

ah, like Al-Jazari's water-powered musical automata in 1206, or Athanasius Kircher's marble machine in the 17th century. or (for more modern examples) Raymond Scott's Electronium in 1959, and the Rhythmicon in 1931.

Is this another fake like the Google bot that made reservations at a restaurant?
