Show HN: Subvocal – Talk to your computer without making noise

200 points aarushyadav 1 hour ago 149 comments

Hi HN, we're Aarush and Arnav from The Subvocal Company (YC F26). We’re building smart glasses that let you talk to your computer without talking out loud. You can mouth words silently and discreetly and the glasses decode them to text at the speed of speech.

Here's a video of Dave from YC trying it out: https://www.youtube.com/watch?v=9QdX1eObVYI

(Edit: you don't actually have to move your lips or even open your mouth for this to work! Since the RF can see inside your mouth the system can be fine tuned on "internal speech". This isn't the automatic tongue movements that occur when "thinking" words to yourself, but more like mouthing with your lips closed. It's a bit weird to do, but with practice, we have been able to get it down pretty well.)

Arnav and I were studying CS at Georgia Tech at the beginning of the year, with no experience in silent speech or sensing. We were both AI-native builders and power users of Wispr Flow. What bugged us was not being able to use these tools in the library (or an office) or in public. At Stanford’s TreeHacks in February, we decided to build the most technically ridiculous thing we could think of. We’d read about AlterEgo, a silent speech system out of MIT’s Media Lab, and wanted to recreate it in 36 hours. We built a crude prototype, sticking EMG electrodes onto my face:

https://drive.google.com/file/d/1mwhv5HZMz3UTevdrgwS5O7g2jWV...

We got it to kind of work at a letter level in a very janky way. It wasn’t good enough to win the hackathon, but convinced us to go all in. The first time I typed a sentence without anyone noticing, I felt the magic of the technology.

We quickly realized EMG (reading muscle electrical signals) wouldn’t work:

- Signal changes due to sweat

- Electrical interference

- Placement variability

- Most importantly, no one wants to stick electrodes onto their face!!

So we switched to RF and built the glasses you see now. They emit radio waves, similar to Bluetooth, that pass through your face. As they cross the tongue, lips and soft palate, they’re modulated by silent mouthing. We train foundation models on this data to decode these perturbations to text.

Despite prior academic research, getting this to work was a huge engineering challenge. First we built an extremely low noise RF sensing stack. Then we had to place antennas so their fields overlapped maximally with the articulators. Our first attempt on glasses failed completely, so we reverted to old habits and taped antennas on our face:

https://drive.google.com/file/d/1ks0dS0eZiTV9EqSFsyB_w5BBjpc...

Since taping antennas consistently in the same spot and angle was hard, we created this weird but effective head rig to hold them in place:

https://drive.google.com/file/d/1rhzNFpdDzr7oHk0isFY70dkoV4C...

This worked, but obviously wasn’t a product yet. So we worked deep in simulations to design glasses that could hold the antennas.

That evolved into our design now, with antennas embedded within the frames. Once we established there was a signal, the next hurdle was cross-user generalization. Everyone’s facial anatomy, and hence RF signal patterns, are vastly different. We tried algorithmic workarounds but realized the only lever was to massively scale pretraining data.

So that’s what we did. We set up booths in our office and paid people to read prompts wearing our glasses, to pretrain our models on. This produced a beautiful scaling curve, with errors falling quickly as we scaled our dataset and cross-user performance becoming genuinely compelling (as you see in the video above; Dave only had a short 20-sentence calibration).

We always heard about building things from first principles but never understood it before this. We tried tackling it top down but completely failed. Only when we broke each component (the antenna, electronics, ML) down to its fundamentals to understand and optimize it did we get it to work really well.

Over the next few months we’re continuing R&D to turn our prototype glasses into the slick product on our website and ship in Q1 2027. We’re also scaling up our dataset to improve performance on edge cases.

For anyone who loves voice dictation but hates using it around people, we’ve opened preorders for our first batch of 500 units, with a $200 discount off the final price. Allocation is running out quickly, so get yours at https://subvocal.co/preorder!

This is what I thought the original post was about. The glasses you have to wear is where that lost me.

If we could get lip-reading via your computer/phone camera down perfectly, that's the real win. Making people wear your goofy frames is where you lose a massive portion of people. Nobody wants to look like Zuckerberg lol

aarushyadav 1 hour ago | parent

Lip reading is one of the other modalities we tried as well beyond IMU, EMG and RF! We worked a lot on fine tuning Auto-AVSR, one of the most commonly used open source lipreading models. It's very enticing to work on, since it gets to about 17% word error rate, which looks good enough that you would think working on it further would get it down to product quality, but we found there's an information-theoretic limit on the modality. Speech has 40 phonemes, but only about 12 to 15 visemes (externally visually separable phonetic states). For example P and B look very similar from a camera. This causes the scaling laws on lipreading to flatten out at an error that's too high to be product ready but just low enough to make for a good demo. Our original plan was actually to ship a lipreading software to see if people would want this behavior, but we realized you couldn't make lipreading work!

Now that is insightful! The demo definitely fooled me and even the first repo requires you to train the model.

Lip reading AI would be pretty big since privacy would probably go out the window.

aarushyadav 1 hour ago | parent

Yup we worked with IMUs as well when we started this. They measure aggregated face motion, so cannot distinguish between fine phonetic classes, only broad words. The open source demo got to a 5 word classifier, I believe. We tried a lot to make IMUs work too, in various form factors, but the signal doesn't contain enough information for open ended decoding beyond classifying between a few words. We would have loved to be able to just push software!

Neat! I don't like talking to my computer (audibly or not), but that's a cool demo.

How have the glasses been received? I don't understand why they're required, is it only to have a consistent mount point for the radar sensor, relative to the face? Have you thought about a throat mic?

kennywinker 59 minutes ago | parent

It looked like there was a throat mic in the first shot... it seems counterintuitive that you'd get better performance out of lidar on face muscles than on a throat mic.

aarushyadav 34 minutes ago | parent

No throat mic, the first image uses EMG (muscle electrical signal) sensors. A throat mic only works if you're still actually whispering (not fully silent) and is also a weird form factor for a consumer device, which is why we didn't go with it!

I was just trying to help a vibe coder and immediately noticed that their README.md was over 2,000 lines long. I asked, "Why is your readme so long?" and their response was, "This is just a really complicated application."

The app essentially manages a bunch of TODO items written in markdown.

derefr 47 minutes ago | parent

For some reason AI coding agents seem to think a README should be a Product Requirements Document (PRD).

I think it's because most projects don't have any settled place (or at least, any place that lives inside the project's source-code repo) to record PRD-like information.

But because AI coding agents really do benefit from having PRD-like info (i.e. a hierarchical breakdown of the "intended what" and "intended how" of the system that "should" exist in the repo, kept updated to reflect changing ideas about those intentions), they really want to record that type of info somewhere, so they can then reference it.

AI coding agents don't seem to have any "taste" (or maybe "confidence"?) when it comes to asserting that even if you don't already have a separate PRD-like file in the repo, you should have one, if you want the agent to do its job well, and so it would request you to let it create one (or just automatically do it.) Instead, they just shrug and cram the PRD stuff into whatever structure you do already have. Which, if you're starting fresh with a greenfield project, is usually just a README.

(I hypothesize that if you tell an AI coding agent to use Behavior-Driven Development [BDD] on a greenfield project, it'll probably lean toward maintaining its PRD-like info in the form of BDD test cases. Haven't tried this experiment yet; would be interested to know the outcome!)

LatencyKills 39 minutes ago | parent

That is exactly what happened in this case; the readme was the PRD.

Throughout the document Claude kept claiming that issues were "mitigated but not fixed". They were essentially bandaid fixes for things it couldn't figure out. When I pointed this out to the author he said, "Well Claude thinks it works."

I wonder what happens to software when enough people try to ship projects like this.

Yup that makes sense. Thanks for the feedback, we'll make some changes shortly!

tomhow 1 hour ago | parent

I'm curious about whether this could be done with the hardware mounted on top of the laptop screen or on a stand on the desk, rather than the glasses form factor. Have you explored this?

aarushyadav 1 hour ago | parent

Yes, we have! The same kind of RF doesn't work in that form, since it is attenuated strongly over that big of a distance. But the other interesting alternative we tried it mmWave radar, RF at about 60 GHz, the same band as 5G. This is much more similar to conventional radar, in that it would bounce off the face rather than passing through it like our current system. We found a few problems with this: 1. It faced the same issue as cameras. mmWave radar has a very low penetration in tissue, so it basically just bounced off the mouth. This only let us see visemes, which aren't enough to get to a low error rate as complete phonetic decoding can. 2. While mmWave radar can detect skin movement as small as a few microns via Doppler shift (given it's small wavelength), its spatial resolution with most systems is quite low. For example, it can tell that something moved 2 microns but within a 5cm x 5cm block. This coarse information makes it very hard to decode

That's why we weren't able to make something that can mount to your laptop. We're trying to make a necklace form factor at some point in the future though, but can't give a date on this!

TechSquidTV 1 hour ago | parent

I would be fairly interested if this works without opening my mouth. Like, if you can nail _micro_ tongue movements, it would feel pretty close to thought.

aarushyadav 1 hour ago | parent

It actually can! Since the RF can see inside your mouth the system doesn't inherently need lip movements and can be fine tuned on what we call "internal speech". Note that this isn't the automatic tongue movements that occur when "thinking" words to yourself, but it's rather like mouthing with your lips closed. We don't often lead with this since it's weird for many people to do, but with a bit of practice, we have been able to get it down pretty well.

hk__2 52 minutes ago | parent

But how would you distinguish all the sounds that don’t require any tongue movement, like (most of?) the vowels?

aarushyadav 44 minutes ago | parent

There's subtle changes in internal speech muscles as well often for those kinds of movements, and where it does seem ambiguous language context is usually enough to distinguish

popap 1 hour ago | parent

That is fascinating. How do the radio waves get modulated? Do you think it is possible to use this technique for spying technology, with remote transmitters and receivers intersecting a person's facial anatomy to pick up the details of even a whispered or muttered conversation?

aarushyadav 1 hour ago | parent

Most probably not possible to do this remotely, since this kind of RF needs to be transmitted through the face, and if you transmit them from too far away very few of them will actually take a path that goes through the face and comes back to your receiver.

They get modulated since your mouth is a complex dielectric environment. Tissue, water, and air have different dielectric constants (different permittivity to RF) and the motion of the muscles in this medium leads to interactions with the waves that fill it, changing their phase and amplitude as they propagate.

Do most people talk faster than they can type? It's the opposite for me - I also read aloud slower than I can read in my head.

aarushyadav 52 minutes ago | parent

Most people type at 40-50 WPM. Developers can often type at 70-100 WPM. Meanwhile, most people can talk at 120-200 WPM. Beyond just speed, we've found with many people that talking things out tends to flow more naturally, since it's often a lower friction action so people don't "sanitize" the text in their head before outputting it. Leads to better prompts quite often :)

achandra03 41 minutes ago | parent

> talking things out tends to flow more naturally,

I've found the opposite. Typing feels much more "deliberate", and of course you can hit backspace but you can't un-speak a word. With prompting, I've found that, in general, speaking leads to lower-quality results than typing.

cogythea 39 minutes ago | parent

Not everyone. I, at least, definitely overthink what I type, and while I end up with nice-ish sentences in my prompts it takes a lot longer than a train of thought that the AI parses correctly most of the time anyway.

chicagobuss 29 minutes ago | parent

When I try talking for prompting my coding agents, I'm always severely disappointed with the specificity of the prompt. It's just much easier for me to "talk about" coding specifics with a keyboard than it is for me to speak about them, for some reason.

I suspect this has to do with the nature of the work you're doing; I dunno, just count me firmly in the camp of people who only rarely feel like I can express a thought sufficiently for coding agents with their voice.

Also, speech is probably bottlenecked by speed of thought, not making the sounds. I recall some study showing that data rate is pretty consistent between languages, despite wpm varying significantly due to language verbosity. You can try it yourself: try to quickly repeat “one two three four five” then try to read a paragraph out loud as quickly as you can, I bet you can feel the first strain your muscles and the second your brain, and I bet the first blows your typing wpm out of the water.

Most people talk faster than they can type. 80 wpm voice chat is easy for everyone. 80 wpm typing filters out most typists.

mrngld 33 minutes ago | parent

This has been an interesting thing for me to watch as it's such a case of people having widely different experiences. I'm sure people that didn't grow up on a keyboard like me can probably talk quicker than they type, but even aside from me being a fairly good typist my speech is held up by being a bit more halting, a bit more of backtracking on word choice, sometimes not quite the same 'voice' of writing as I'm aiming for, all of which obliterates any speed advantage it'd have for me.

But happy to see people get more options.

This reminds me of Eternity's End by Jeffrey Carver and the implants they had. Released in 2000 but the more time goes on the more the neural implant technology is coming about. To be fair I think Enders Game had similar tech to detect subvocal speech like this product.

> This has been an interesting thing for me to watch as it's such a case of people having widely different experiences.

Same. I'm often told I talk too fast, but I feel I communicate slowly because a lot of my fast speech involves halting and backtracking and such.

I can easily type 100WPM+, but I trivially blast out a few paragraphs of perfectly adequate text in a few seconds and then spend a few minutes re-editing it.

All of them are visionary and we would think that ppl gonna like them…

Well… ordinary people want boring tech.

This will be similar with whispering to glasses… Visionaries will like it… and return to missionary (boring) s*x (I hope that I don’t get a ban.)

Myself, I would buy these glasses immediately. But I would hate them as well as I would think I am insane (who wants to talk to yourself?).

Edit: Dang replied. I wish all the best to the team behind “whisper glasses”. It is amazing. Connect it with ElevenLabs and you rule the world. (Previous: It wasn’t meant a hate speech.)

(Don't worry, we're not going to ban you.)

A tasteless sex reference is one thing, but shallow-curmudgeonly dismissal of new work is the real sin here!

sixtyj 26 minutes ago | parent

This wasn’t meant as a hate. Sorry if it sound so. I really like them, I would buy them. Immediately. Sign me in.

But I think (and see) that people prefer boring tech. Whisper glasses is amazing. But most people will probably find it creepy. (Pareto applied.). I hope I am wrong. These guys are like from sci-fi.

So it's a pair of glasses that can transcribe when you mouth words silently? I still don't know how it works, they say no cameras and it works with noise so I assume sort sort of reverse bone conducting?

Says right in the description that they are using radio

The whole paragraph above explains it. Radio through your head.

Are there any health risks with this method?

Edit: mostly concerned about RF near my eyes for 8 hours a day.

hirako2000 41 minutes ago | parent

Sensorimotor debility is a thing. This gadget surely won't help with it.

HIP_HOP 40 minutes ago | parent

Yeah, so a recent study discovered that talking silently makes other people harder to hear you so they think they have problem hearing.

aarushyadav 18 minutes ago | parent

No, the RF is very low power and can safely be active on your face for long periods. We've done a lot of investigation and verification with safety. While doing R&D the first 2 months we collected hundreds of hours of data on ourselves with various configurations, so we made sure it was safe before :)

Also, the RF transmission only activates when you're actively dictating.

Infuriating website UX, you really must add the scrollbar back. Apple do shiny things like this but they know you can't get rid of the scrollbar and piss people off trying to look at information

Yup, Q.ai is different tech and we have our IP :)

They use speckle patterns of a laser shone onto the skin, which is sensitive down to tens of nanometers. Pretty cool tech

Watched the demo video… and if this is satire: incredibly well executed

aarushyadav 13 minutes ago | parent

It's not :)

kenferry 37 minutes ago | parent

This is very cool, but oddly, the site is TOO focused on the user problem being solved to the extent that it feels like snake oil. The issue is that this is contrary to people's experience of what is possible, so without discussing WHY you can do this, it looks like a scam or vaporware.

aarushyadav 21 minutes ago | parent

Fair feedback, will take into account. Looking to change up the site quite a bit soon!

collabs 36 minutes ago | parent

I am so glad to see an unpolished early look and an honest evaluation of about five percent error rate in the YouTube video. The really cool stuff will be the applications on top of `subvocal` though at least in my opinion.

So this could take "noise canceling" to a whole new level if you could somehow "speak" across a loud bar or across the world, for that matter. Being integrated into something like Signal or similar end to end encrypted platform would be interesting as well.

aarushyadav 23 minutes ago | parent

Yep, I agree. Noise cancellation is a feature we want to release at some point in the future. Using the RF to denoise a very noisy audio signal which has you speaking in it. And we'll release an SDK as well a few months after shipping to build stuff on top of it!

clkao 35 minutes ago | parent

this is super cool. I did some digging about current research on avsr using video and lip point cloud movement a while back. found projects like https://github.com/amanvirparhar/chaplin but this seems more promising!

json_hero 35 minutes ago | parent

Should really just be like a leap motion device on the desk, glasses are so gimmicky and aren't gonna fly for people with prescriptions (a large set of people in-front of computers all day)

xur17 23 minutes ago | parent

People with prescriptions can just get versions with prescriptions in them (this is a thing for "smart" glasses already).

conductr 18 minutes ago | parent

Can, but as a new product it is going to limit their adoption rate by some pretty significant amount.

One of the coolest things I have recently seen but would love some details. It also got me thinking a about this recent Neuralink post.

You can have a silent conversation with someone else wearing the device? This does not bode well for casinos.

A casino would have no problem seeing mouth movement.

This is super cool. I think it's the first piece of additional hardware I've even considered pre-ordering.

I did research in this space about eight years ago. Our approach was to look at deformations in the ear canal. Rumor has it that Apple AirPods will have sensors in the ear canal. I was hoping to use those sensors with our app, but it looks like Apple is not going to provide access to the raw sensor data. I expected Apple is going to support subvocal speech pretty soon.

aarushyadav 7 minutes ago | parent

From my understanding decoding via ear deformation requires the mouthing to be quite exaggerated. I am also looking forward to Apple launching it soon though, hopefully it gets more people excited and aware about the category at least

lukko 26 minutes ago | parent

Great work!

Really like seeing the early prototypes here, and would love to see more on how the RF tech works on the website.

Are you able to patent it?

dogscatstrees 22 minutes ago | parent

Let's go! Love the idea. Like the analog to bone conduction earbuds. Just please don't turn into WisprFlow where they route the voice metadata, unbeknownst to many, to a third party partner who stores and mines it for who-knows-what. Good luck fellas.

aarushyadav 18 minutes ago | parent

Of course! Privacy is important!

jdironman 17 minutes ago | parent

What I would really like is a washable "cyber suit". Mock or turtle neck (for the voice / STT capture / control), EEG sensors, breathing rate, blood pressure, gestures via arm motion sensors,). Removable rechargeable battery module to wash the torso / shirt slap it on a clean one. For EEG it would have to be pretty compressed though, so not sure it would be comfortable enough to wear to sleep? maybe only an internal harness needs to be that compressed. not sure. I'm tired of wearing a Fitbit, or glasses, or these different things people have to look at, keep up with, break easy etc.

mmaths 17 minutes ago | parent

I wonder if in a couple of years we gonna have some teeth implant that will capture sounds to our devices.

popupeyecare 14 minutes ago | parent

Preordered!

Can we use RF for other medical applications? As an anesthesiologist, we do nerve blocks before surgeries or for pain. One rough indicator that it's working is muscle paralysis. Also similar for botox.

Very interested.

aarushyadav 3 minutes ago | parent

Not sure, but definitely sounds interesting! I do know there was one company trying to use mmWave RF to track patient vitals like breathing patterns and heart rate without having anything hooked up to / touching them

howunfortunate 13 minutes ago | parent

This is:

1. Insanely cool

2. Gives me serious "whispering earring" vibes. Imagine having a full on conversation with an AI via subvocalization and listening with ear bud to guide you throughout the day. https://gwern.net/doc/fiction/science-fiction/2012-10-03-yva...

Much respect for actual innovation. I hope you get filthy rich.

airbreather 11 minutes ago | parent

Website is shit, "how it works" tells you nothing much useful about how it works, and I assume there is some custom hardware (as described in the post above) but nowhere on the website I could see this actually said, and therefore zero indication of the size of the interface electronics etc etc

vessenes 10 minutes ago | parent

Just preordered -- glasses request: there's no way to say it nicely, I have a big nose. With a high bridge. Many glasses are really tough to get properly placed; may I request you not give up on the pads w/metal adjusters that you have in the product photos? Don't let a designer take them away from you, us folks not one standard deviation from 'normal' noses will thank you.

Second, how tough is this signal processing? Will it be done on-glasses, or through an app? Third, what's the equivalent of a wake word for these? I'm reminded of the Apple Vision Pro radar to see if your fingers are clicking. I could imagine a lot of modalities where I want to just start talking and have things happen, and a lot where I don't want the glasses to pick it up. Fourth, I think a cool voice change demo would be rad -- not sure what latency is like, but if you could get it end to end under like 250ms you could probably have someone exaggerate the mouth movements and pipe out audio of them talking like someone else. Which would be another really cool demo.

Super cool. You're going to be working 80 hour weeks for the next year, I'm excited to see what you put out!

0x4e 8 minutes ago | parent

For the ones thinking this is great, have you actually tried to talk without making sounds?

I don't think it is an intuitive action at all and I became self-conscious about not making a sound rather than talking like I normally would.

I suppose it would require some "getting used to."

Regardless, I think it is a cool idea and a real problem. Sometimes I don't want to type nor talk out loud so I find myself whispering at my phone like I'm telling it a dirty secret.

As I'm writing this, I think this kind of product might not hot the market for consumers, but I'm seeing this used by Flock like companies to spy on people's speech, so kudos on making machine lip reading a thing!

If the tech is mostly in the glasses temples, I would prefer to have something that attaches to my existing glasses. I have prescription glasses and a big head, tried the Even G2 smart glasses and the available frames set just too small for me

Very cool. I suspect you guys will get scooped up by a bigger player working on smart glasses soon.
