I read this, then realized I needed a browser extension to read my long case study and made a browser interface of this and put this together:

You can do the same thing with Firefox' Reader Mode. On Linux you have to set up speech-dispatcher to use your favorite TTS as a backend.Once it is set up, there will be an option to listen the page.

Oh this is sweet, thanks for sharing! I've been a huge fan of Kokoro and event setup my own fully-local voice assistant [1]. Will definitely give Pocket TTS a go!

Kokoro is better for tts by far

For voice cloning, pocket tts is walled so I can't tell

Thanks for sharing your repo..looks super cool.. I'm planning to try out. Is it based on mlx or just hf transformers?

lukebechtel|1 month ago

Nice!

Just made it an MCP server so claude can tell me when it's done with something :)

macOS already has some great intrinsic TTS capability as the OS seems to include a naturally sounding voice. I recently built a similar tool to just run the "say" command as a background process. Had to wrap it in a Deno server. It works, but with Tahoe it's difficult to consistently configure using that one natural voice, and not the subpar voices downloadable in the settings. The good voice seems to be hidden somehow.

I just setup pushover to send a message to my phone for this exact reason! Trying out your server next!

Love this.

It says MIT license but then readme has a separate section on prohibited use that maybe adds restrictions to make it nonfree? Not sure the legal implications here.

CGamesPlay|1 month ago

For reference, the MIT license contains this text: "Permission is hereby granted... to deal in the Software without restriction, including without limitation the rights to use". So the README containing a "Prohibited Use" section definitely creates a conflicting statement.

jandrese|1 month ago

The "prohibited uses" section seems to be basically "not to be used for crime", which probably doesn't have much legal weight one way or another.

Buttons840|1 month ago

Good question.

If a license says "you may use this, you are prohibited from using this", and I use it, did I break the license?

MatthiasPortzel|1 month ago

Tried to use voice cloning but in order to download the model weights I have to create a HuggingFace account, connect it on the command line, give them my contact information, and agree to their conditions. The open source part is just the client and chunking logic which is pretty minimal.

syockit|1 month ago

From my understanding, the code is MIT, but the model isn't? What consitutes a "Software" anyway? Aren't resources like images, sounds and the likes exempt from it (hence, covered by usual copyright unless separately licensed)? If so, in the same vein, an ML model is not part of "Software". By the way, the same prohibition is repeated on the huggingface model card.

iamrobertismo|1 month ago

Yeah, I don't understand the point of the prohibited use section at all, seems like unnecessary fluff.

pain_perdu|1 month ago

I'm psyched to see so much interest in my post about Kyutai's latest model! I'm working on part of a related team in Paris that's building off Kutai's research to provide enterprise-grade voice solutions. If anyone building in this space I'd love to chat and share some our upcoming models and capabilities that I am told are SOTA. Please don't hesitate to ping me via the address in my profile.

armcat|1 month ago

Just want to say amazing work. It's really pushing the envelope of what is possible to run locally on everyday devices.

mgaudet|1 month ago

Eep.

So, on my M1 mac, did `uvx pocket-tts serve`. Plugged in

> It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way—in short, the period was so far like the present period, that some of its noisiest authorities insisted on its being received, for good or for evil, in the superlative degree of comparison only

(Beginning of Tale of Two Cities)

but the problem is Javert skips over parts of sentences! Eg, it starts:

> "It was the best of times, it was the worst of times, it was the age of wisdom, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the spring of hope, it was the winter of despair, we had everything before us, ..."

Notice how it skips over "it was the age of foolishness,", "it was the winter of despair,"

Which... Doesn't exactly inspire faith in a TTS system.

Paul_S|1 month ago

All the models I tried have similar problems. When trying to batch a whole audiobook, the only way is to run it, then run a model to transcribe and check you get the same text.

sbarre|1 month ago

Yeah Javert mangled up those sentences for me as well, it skipped whole parts and then also moved words around

vvolhejn|1 month ago

Václav from Kyutai here. Thanks for the bug report! A workaround for now is to chunk the text into smaller parts where the model is more reliable. We already do some chunking in the Python package. There is also a more fancy way to do this chunking in a way that ensures that the stitched-together parts continue well (teacher-forcing), but we haven't implemented that yet.

small_scombrus|1 month ago

Using your first text block 'Eponine' skips "we had nothing before us" and doesn't speak the final "that some of its noisiest"

I wonder what's going wrong in there

memming|1 month ago

interesting; it skipped "we had everything before us," in my test. Yeah, not a good sign.

GaggiX|1 month ago

I love that everyone is making their own TTS model as they are not as expensive as many other models to train. Also there are plenty of different architecture.

Another recent example: https://github.com/supertone-inc/supertonic

nunobrito|1 month ago

Thank you. Very good suggestion with code available and bindings for so many languages.

Ok, who knows where I can get those high-quality recordings of Majel Barrett' voice that she made before she died?

freedomben|1 month ago

TOS computer voice must be my computer's voice. And after every command I run, I need a "Working."

dale_glass|1 month ago

Is there any TTS engine that doesn't need cloning and has some sort of parameters one can specify?

Like what if I want to graft on TTS to an existing text chat system and give each person an unique, randomly generated voice? Or want to try to get something that's not quite human, like some sort of alien or monster?

unleaded|1 month ago

You could use an old-school formant synthesizer that lets you tune the parameters, like espeak or dectalk. espeak apparently has a klatt mode which might sound better than the default but i haven't tried it.

bkitano19|1 month ago

You can use voice prompting; it's supported on ElevenLabs and Hume.

Imustaskforhelp|1 month ago

Perhaps I have been not talking to voice models that much or the chatgpt voice always felt weird and off because I was thinking it goes to a cloud server and everything but from Pocket TTS I discovered unmute.sh which is open source and I think is from the same company as Pocket TTS/can I think use Pocket TTS as well

I saw some agentic models at 4B or similar which can punch above its weights or even some basic models. I can definitely see them in the context of home lab without costing too much money.

I think atleast unmute.sh is similar/competed with chatgpt's voice model. It's crazy how good and (effective) open source models are from top to bottom. There's basically just about anything for almost everyone.

I feel like the only true moat might exist in coding models. Some are pretty good but its the only industry where people might pay 10x-20x more for the best (minimax/z.ai subscription fees vs claude code)

It will be interesting to see if we will see another deepseek moment in AI which might beat claude sonnet or similar. I think Deepseek has deepseek 4 so it will be interesting to see how/if it can beat sonnet

(Sorry for going offtopic)

StevenNunez|1 month ago

Great find! unmute was a trip to play with

dust42|1 month ago

Good quality but unfortunately it is single language English only.

riedel|1 month ago

I am also quite irritated by the fact that many TTS fail to state what language (and probably even dialect) they support. Actually to support a really good workflow for many Europeans (and probably also the rest of the world) one would actually need a multi language models that also support the use foreign words within one's own language. I am using a local notification reader on my smartphone (with SherpaTTS) and the mix of notification language as well as languages embedded in each other makes the experience rather funny at times.

jiehong|1 month ago

Agreed.

I think they should have added the fact that it's English only in the title at the very least.

phoronixrly|1 month ago

I echo this. For a TTS system to be in any way useful outside the tiny population of the world that speaks exclusively English, it must be multilingual and dynamically switch between languages pretty much per word.

Cool tech demo though!

nmstoker|1 month ago

It's impressive but it's a shame that it's 2026 and despite remarkably lifelike speech, so many models fall on common issues like heteronyms ("the couple had a row because they couldn't agree where to row their boat"), realistic number handling and so on.

woadwarrior01|1 month ago

Yeah most models are quite bad at it. The industry term for it is: homograph disambiguation.

akx|1 month ago

It's pretty good. And for once, a software-engineering-ly high-quality codebase, too!

All too often, new models' codebases are just a dump of code that installs half the universe in dependencies for no reason, etc.

snvzz|1 month ago

Relative to AmigaOS translator.device + narrator.device, this sure seems bloated.

Paul_S|1 month ago

The speed of improvement of tts models reminds me of early days of Stable Diffusion. Can't wait until I can generate audiobooks without infinite pain. If I was an investor I'd short Audible.

asystole|1 month ago

An all-TTS audiobook offering is just about as appealing as an all-stable-diffusion picture gallery (that is, not at all).

everyday7732|1 month ago

It's not perfect, but I already have a setup for doing this on my phone. Add SherpaTTS and Librera Reader to your phone. (both available free on fdroid).

Set up SherpaTTS as the voice model for your phone (I like the en_GB-jenny_dioco-medium voice option, but there are several to choose from). Add a ebook to librera reader and open it. There's an icon with a little person wearing headphones, which lets you send the text continuously to your phone's tts, using just local processing on the phone. I don't have the latest phone but mine is able to process it faster than the audio is read, so the audio doesn't stop and start.

The voice isn't totally human sounding, but it's a lot better than the microsoft sam days, and once you get used to it the roboticness fades into the background and I can just listen to the story. You may get better results with kokoro (I couldn't get it running on my phone) or similar tts engines and a more powerful phone.

One thing I like about this setup is that if you want to swap back and forth between audio and text, you can. The reader scrolls automatically as it makes the audio, and you can pause it, read in silence for a while yourself and later set it going from a new point.

gempir|1 month ago

I feel like TTS is one of the areas that as evolved the least. Small TTS models have been around for like 5+ years and they've only gotten incrementally better. Giants like ElevenLabs make good sounding TTS but it's not quite human yet and the improvements get less and less each iteration.

rowanG077|1 month ago

Wouldn't audible be perfectly positioned to take advantage of this. They have the perfect setup to integrate this into their offering.

donpdonp|1 month ago

it'd be nice to get some idea of what kind of hardware a laptop needs to be able to run this voice model.

donpdonp|1 month ago

for example, How much disk is needed? I started the uvx command and it started to download hundreds of megabytes. How much cpu ram is necessary and how much gpu ram is necessary? will an integrated intel gpu work? some ARM boards have a dedicated AI processor, are any of those supported?

febin|1 month ago

I've vibecoded a Rust port of Pocket TTS using candle.

https://github.com/jamesfebin/pocket-tts-candle

The port supports:

- Native compilation with zero Python runtime dependency

- Streaming inference

- Metal acceleration for macOS

- Voice cloning (with the mimi feature)

Note: This was vibecoded (AI-assisted), but features were manually tested.

OfflineSergio|1 month ago

This is amazing. The audio feels very natural and it's fairly good at handling complext text to speech tasks. I've been working on WithAudio (https://with.audio). Currently it only uses Kokoros. I need to test this a bit more but I might actually add it to the app. It's too good to be ignored.

syntaxing|1 month ago

Is there something similar for STT? I’m using whisper distill models and they work ok. Sometimes it gets what I say completely wrong.

smallerfish|1 month ago

Hopefully the browsers will improve their built in TTS soon. It's still pretty unusable unless you really need it.

sysworld|1 month ago

And OS's. Mac has some decent models, but kokoro is much better. Even this one is better.

Zardoz84|1 month ago

I'm missing the old days that connecting a SPOKE256 to the Spectrum and making it speak, looked like magic.

_ache_|1 month ago

It's very impressive! I'm mean, it's better than other <200M TTS models I encounter.

In English, it's perfect and it's so funny in others languages. It sounds exactly like someone who actually doesn't speak the language, but got it anyway.

I don't know why Fantine is just better than the others in others languages. Javer seems to be the worst.

Try Jean in Spanish « ¡Es lo suficientemente pequeño como para caber en tu bolsillo! » sound a lot like they don't understand the language.

Or Azelma in French « C'est suffisament petit pour tenir dans ta poche. » is very good.I mean half of the words are from a Québécois accent, half French one but hey, it's correct French.

Però non capisce l'italiano.

It'd be great if it supported stdin&stdout for text and wav. Then it could get piped right into afplay

gabrieldemarm|1 month ago

Gabriel from Kyutai here, we do support outputting wav to stdout. We don't support reading text from stdin but that should be easy enough. Feel free to drop a pull request!

Question: does anyone recommend a TTS that automatically recognizes emotion from the text it self?

sofixa|1 month ago

Gradium (https://gradium.ai/), a commercial company offshoot of Kyutai (open source lab), are focusing on emotion (both being able to recognise emotion and also understanding what emotion to use depending on context). I don't think any of their public existing models already does that, but they demoed it pretty impressively at the ai-Pulse conference.

fluoridation|1 month ago

Chatterbox does something like that. For example, if the input is

"so and so," he <verb>

and the verb is not just "said", but "chuckled", or "whispered", or "said shakily", the output is modified accordingly, or if there's an indication that it's a woman speaking it may pitch up during the quotation. It also tries to guess emotive content from textual content, such if a passage reads angry it may try to make it sound angry. That's more hit-and-miss, but when it hits, it hits really well. A very common failure case is, imagine someone is trying to psych themselves up and they say internally "come on, Steve, stand up and keep going", it'll read it in a deeper voice like it was being spoken by a WW2 sergeant to a soldier.

butz|1 month ago

How large is the model and is it possible to train it read other languages, not only English?

butz|1 month ago

After pip install pocket-tts all dependencies are 7.4 GB. And it generates at 2x speed on CPu. Neat!

aki237|1 month ago

This is impressive.

I just tried some sample verses, sounds natural.

But there seems to be a bug maybe? Just for fun, I had asked it to play the Real Slim Shady lyrics. It always seems to add 1 extra "please stand-up" in the chorus. Anyone see that?

gabrieldemarm|1 month ago

Hello Gabriel from Kyutai here, maybe it's related to the way we chunk the text? Can you post an issue on github with the extact text and voice? I'll take a look.

aidenn0|1 month ago

I'm sure I'm being stupid, but every voice except "alba" I recognize from Les Miserables; is there a character I'm forgetting?

vvolhejn|1 month ago

Václav from Kyutai here. Yes the original naming scheme was from Les Miserables, glad you noticed! We just stuck to Alba because that's the real name of the voice actor that provided the voice sample to us (see https://huggingface.co/kyutai/tts-voices), the other ones are either from pre-existing datasets or given anonymously.

it is similar to chatterbox as far as realism at half the speed and no gpu needed which leads me to wonder, why is chatterbox so slow ?

Haven't we had TTS for like 20+ years? Why does AI need to be shoved into it all of a sudden. Total waste of electricity.

andhuman|1 month ago

I’ve tried the voice clinking and it works great. I added a 9s clip and it captured the speaker pretty well.

But don’t do the fake mistake I did and use a hf token that doesn’t have access to read from repos! The error message said that I had to request access to the repo, but I’ve had already done that, so I couldn’t figure out what was wrong. Turns out my HF token only had access to inference.
