    What I love about OpenClaw is that I was able to send it a message on Discord with just this github URL and it started sending me voice messages using it within a few minutes. It also gave me a bunch of different benchmarks and sample audio.I'm impressed with the quality given the size. I don't love the voices, but it's not bad. Running on an intel 9700 CPU, it's about 1.5x realtime using the 80M model. It wasn't any faster running on a 3080 GPU though.

    Would an Android app of this be able to replace the built in tts?

    This is awesome, well done. Been doing lot of work with voice assistants, if you can replicate voice cloning Qwen3-TTS into this small factor, you will be absolute legends!

    The example.py file says "it will run blazing fast on any GPU. But this example will run on CPU."I couldn't locate how to run it on a GPU anywhere in the repo.

    You should put examples comparing the 4 models you released - same text spoken by each.

    A lot of good small TTS models in recent times. Most seem to struggle hard on prosody though.Kokoro TTS for example has a very good Norwegian voice but the rhythm and emphasizing is often so out of whack the generated speech is almost incomprehensible.Haven't had time to check this model out yet, how does it fare here? What's needed to improve the models in this area now that the voice part is more or less solved?

    are there plans to output text alignment?

    One of the core features I look for is expressive control.Either in the form of the api via pitch/speed/volume controls, for more deterministic controls.Or in expressive tags such as [coughs], [urgently], or [laughs in melodic ascending and descending arpeggiated gibberish babbles].the 25MB model is amazingly good for being 25MB. How does it handle expressive tags?

    25MB is impressive. What's the tradeoff vs the 80M model — is it mainly voice quality or does it also affect pronunciation accuracy on less common words?

    Really cool to see innovation in terms of quality of tiny models. Great work!
  • DavidTompkins
    This would be great as a js package - 25mb is small enough that I think it'd be worth it (in-browser tts is still pretty bad and varies by browser)
  • janice1999
    What's the actual install size for a working example? Like similar "tiny" projects, do these models actually require installing 1GB+ of dependencies?
  • ks2048
    There's a number of recent, good quality, small TTS models.If the author doesn't describe some detail about the data, training, or a novel architecture, etc, I only assume they just took another one, do a little finetuning, and repackage as a new product.

    This is great. Demo looks awesome.

    I'm still looking for the "perfect" setup in order to clone my voice and use it locally to send voice replies in telegram via openclaw. Does anyone have auch a setup?I want to be my own personal assistant...EDIT: I can provide it a RTX 3080ti.
  • devinprater
    A lot of these models struggle with small text strings, like "next button" that screen readers are going to speak a lot.

    How much work would it be to use the C++ ONNX run-time with this instead of Python? Is it a Claudeable amount of work?The iOS version is Swift-based.
  • great_psy
    Thanks for working on this!Is there any way to get those running on iPhone ? I would love to have the ability for it to read articles to me like a podcast.
  • ilaksh
    Thanks for open sourcing this.Is there any way to do a custom voice as a DIY? Or we need to go through you? If so, would you consider making a pricing page for purchasing a license/alternative voice? All but one of the voices are unusable in a business context.
  • Tacite
    Is it English only?
  • wiradikusuma
    I'm thinking of giving "voice" to my virtual pets (think Pokemon but less than a dozen). The pets are made up animals but based on real animal, like Mouseier from Mouse (something like that). Is this possible?Tldr: generate human-like voice based on animal sound. Anyway maybe it doesn't make sense.
