@voicearena_ai asking a simple question is useful.

Making sure the experiment isolates that question is the hard part.

Are we actually measuring the things we ultimately want our voice AI models to achieve?

The best AI voices are becoming hard to tell apart.
From each other. Not from humans.

🚀 Introducing Turing TTS: an evaluation that measures how often human listeners mistake AI-generated speech for real human speech.

We tested leading TTS models against real human speech. Even the best model fooled listeners only ~10% of the time.

With Turing TTS, we hope to contribute to a broader discussion within the research community about how we measure progress in voice AI.

If one of our goals is to develop speech that is indistinguishable from human speech, how well do our current evaluation methods capture progress toward that goal?

We don’t claim that Turing TTS is the right way forward, or that human indistinguishability should be the goal of every TTS system.

Rather, we hope these findings encourage the community to collectively examine whether blind pairwise human evaluations of naturalness are sufficient, and what else we might need to measure.

Results are now live on @voicearena_ai.

@shobhitbanga Can we make the next release report more informative than higher score, new number one?

[Aarush Yadav @AarushYadav47]

We’ve raised $1.3M from YC & Afore Capital so you never have to type or speak again.

Typing is slow. Talking into your computer is awkward. Subvocal fixes both

Our glasses give you the speed of speech without you making a sound or touching a keyboard.

It tracks your internal speech muscles with non-contact sensing and decodes silent, almost invisible mouthing into text at more than 200 words/min.

Introducing RL with Neural Feedback (RLNF). We have found reliable ways to train AI models to respond to human preferences purely from brain signals.

The example below is a picture of a face that self-transforms into a more attractive version for the subject as they are looking at it.

Every voice agent I use waits for a full stop.

The real calls in this dataset show how rarely people actually do that.

[Shobhit Banga @shobhitbanga]

Drop 1/15: Introducing Joy, a dual-channel conversational dataset.
Real, unscripted conversations between two people, each on their own track. Built to teach voice models how people actually talk: when to listen, when to jump in, when to say “hmm”.

100,000 hours.
50,000 speakers.
10 languages.

@shobhitbanga Real interruption timing is the thing synthetic data never gets right.

@ryandengg @bcantrill @sdtuck @oxidecomputer @EclipseVentures the firm used an investor they didn't like as the exit. the investor had been doing deals for 22 years

[Ryan Deng @ryandengg]

Oxide just raised $445M at a $6B valuation.

@bcantrill and @sdtuck started @oxidecomputer to build the computers the hyperscalers keep for themselves. @EclipseVentures led the seed when nobody else would. now they're profitable, and he says they didn't even need to raise.

i also asked him if AI is a bubble, why america hates data centers, and why every oxide employee makes the same salary.

nontechnical, episode 4.

00:00 $445M at $6B, and they didn't need it

Text-to-speech gets you close. But close isn’t how you’d say it.

So say it yourself, once. HeyGen Voice STS carries the whole performance over to your avatar, down to every pause, emphasis, and whisper.

Test it here: https://t.co/vLI01FKzbM

[Hoorain Chaudhry @hoorain863]

@HeyGen Text prompts for emotional delivery have never worked well for me. This approach of just performing the line yourself makes a lot more sense.

[Hoorain Chaudhry @hoorain863]

@voicearena_ai Great result for @NVIDIAAI. 8.32% deletions against a \~31% median is a big gap.

[Voice Arena @voicearena_ai]

🏆 NVIDIA Nemotron 3.5 Transcribe debuts at #1 among 14 systems on Voice Arena’s Diarization + ASR leaderboard.
Across the full benchmark, it achieves 32.43% cpWER.

This track tests whether a system can get both the words and the speakers right. We evaluated 139 held-out conversations with 2-8 speakers across in-person and online settings, including overlapping speech.

Nemotron 3.5 Transcribe is first in both settings: 34.08% cpWER in person (far field) and 22.13% on online calls.

It has the lowest word deletion rate on the leaderboard. Deletions are 8.32% of reference words, against a median near 31%.

Congratulations to @NVIDIAAI on the release ! 👏
