  • Any recommendation for human like voice AI model for conversation AI?
    2 projects | news.ycombinator.com | 4 Jan 2024
    Fast or good, choose one

    Mozilla's TTS is a python package installable with pip and uses cpu or gpu resources to render a choice of voices, they mostly sound natural and this is the good. https://github.com/mozilla/TTS

    Mycroft's mimic3 is the default voice renderer for the Mycroft project that runs on pi hardware and sounds ok-ish, that is the fast. https://github.com/MycroftAI/mimic3

    There are many others but these are the two I use according to if it needs to run on limited hardware or if the cycles fall freely from the sky.

  • Coqui.ai Is Shutting Down
    4 projects | news.ycombinator.com | 3 Jan 2024
    Coqui-ai was a commercial continuation of Mozilla TTS and STT (https://github.com/mozilla/TTS).

    At the time (2018-ish), it was really impressive for on-device voice synthesis (with a quality approaching the Google and Azure cloud-based voice synthesis options) and open source, so a lot of people in the FOSS community were hoping it could be used for a privacy-respecting home assistant, Linux speech synthesis that doesn't suck, etc.

    After Mozilla abandoned the project, Coqui continued development and had some really impressive one-shot voice cloning, but pivoted to marketing speech synthesis for game developers. They were probably having trouble monetizing it, and it doesn't surprise me that they shut down.

    An equivalent project that's still in active development and doing really well is Piper TTS (https://github.com/rhasspy/piper).

    My solution would be to use a speech synthesis library, maybe eSpeak or Festival, just for ease of use; I think they each provide a library that you could use from C or C++ easily. This one from Mozilla is a more modern system with better-quality output, but it looks like it's set up to run through Python, and I haven't looked at it closely enough to see how much work it would be to get it working for you.

    There is a lot of TTS and SST development going on (https://github.com/mozilla/TTS; https://github.com/mozilla/DeepSpeech; https://github.com/common-voice/common-voice). That is the only way they work: Contributions from the wild.

    unfortunately not yet. I need to expand the library of languages and voices. looking around, it seems only Coqui had some traction re Brazilian Portuguese: https://github.com/mozilla/TTS/issues/160. If you foresee wide adoption of the tech for this locale, hit me up with DM

    Instead, just use Firefox's open-source TTS model: https://github.com/mozilla/TTS
