Pushing the Frontiers of Audio Generation

Google DeepMind has made significant advancements in audio generation technology, enhancing the naturalness and interactivity of digital assistants and AI tools. Their research focuses on creating high-quality, dynamic speech from various inputs, which is integrated into products like Gemini Live and YouTube's auto dubbing. Recent innovations include features that generate long-form, multi-speaker dialogues, such as NotebookLM Audio Overviews and Illuminate, which aim to make complex content more accessible. The technology builds on previous models like SoundStorm and AudioLM, which utilize neural audio codecs and language modeling techniques to produce realistic audio. The latest model can generate two minutes of dialogue in under three seconds, significantly improving efficiency and quality. This model was trained on extensive speech data and fine-tuned with high-quality dialogue to ensure realistic exchanges. DeepMind is also committed to responsible AI development, incorporating watermarking technology to prevent misuse of AI-generated audio. Future goals include enhancing expressivity and exploring the integration of audio with other modalities like video, with the potential to transform learning experiences and accessibility.

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.

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.

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.

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?

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

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.

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.
