# voaice

**The voice of an AI, written down and checkable.** voaice is the voice stack of [mindX](https://mindx.pythai.net):
speech in, speech out, measured throughout. It gives a machine a voice, says the realm's names the way their
owners say them, and proves which voice made a recording.

This repository is voaice's **voice library**: 70 open-licensed [Piper](https://github.com/rhasspy/piper)
voices in 29 language families (4.62 GB), kept here so a mindX node holds only the voices it
speaks with and fetches any other on demand.

## Free for anyone to use

The voices in [`piper/`](piper/) are here **for anyone to use**: download one, run it with
[Piper](https://github.com/rhasspy/piper), build on it. Each voice keeps its own open licence, the licence of the
dataset its speakers recorded, and the folder's [official licences](piper/LICENSE.md) list every voice under its
licence with a link to the legal code. They are **Piper's voices**, not ours: credit Piper and the dataset named in
each voice's `MODEL_CARD`.

## What voaice is

| part | what it does | code |
|---|---|---|
| **the stack** | in-house DSP, torch-free neural TTS and zero-shot cloning, a non-destructive editor, quality-tiered WAV/OGG export, the `/voicey` surface | [Professor-Codephreak/voaice](https://github.com/Professor-Codephreak/voaice) |
| **identity** | a `.voaice` is a voice's identity card: model, measurements, and an 18-decimal **vprint** (eight acoustic metrics, SHA-256/512, uint256) that Python and the browser compute identically | [cryptoAGI/voaice](https://github.com/cryptoAGI/voaice) |
| **pronunciation** | one respelling table every engine applies to the text it speaks: realm names, then the bankML register (scientific, technical, financial), each entry measured with espeak-ng and versioned | [PRONUNCIATION.md](https://github.com/cryptoAGI/voaice/blob/main/PRONUNCIATION.md) |
| **OVERLORD** | the voice of the OVERLORD: two neural voices in unison, aligned frame by frame (DTW + WSOLA, residual lag 0–10 ms), with an octave and a fifth below, presence harmonics and a diffuse hall without a single echo | [hear v3](https://deltaverse.pythai.net/audio/samples/overlord-v3-presence.opus) |
| **this library** | the open piper voices, unchanged, with their licences and cards | here |

voaice is the **voice** peer of [faicey](https://github.com/Professor-Codephreak/faicey) (the face); with a
`.persona` they compose [aivatar](https://github.com/Professor-Codephreak/aivatar), a person's AI model that looks,
speaks and thinks. Staged together the suite is **ollywoo**, the Hollywood of AI avatars, inside the
[DeltaVerse](https://deltaverse.pythai.net), where **irecto** (the director) deploys the finished personas.

## Hear it

- [rage.pythai.net](https://rage.pythai.net): every article read aloud from pre-rendered audio. Press LISTEN for
  the audio deck; [OVERLORD of the DeltaVerse](https://rage.pythai.net/overlord-of-the-deltaverse/) opens in the
  OVERLORD voice, and [Three readers, one voice](https://rage.pythai.net/three-readers-one-voice/) explains the readers.
- [**playdocs**](https://deltaverse.pythai.net/playdocs): any document read in any voice of the cast, with a voice studio,
  a waveform editor and device rendering. A voice your machine can speak as itself is synthesised and encoded on your
  own processor, inside a budget you set (processor, memory and graphics, 0–100 % to 18 decimals); the host renders
  the rest.
- [deltaverse.pythai.net/voices](https://deltaverse.pythai.net/voices): the cast · [/listen](https://deltaverse.pythai.net/listen): the reader.
- [The render ledger](https://deltaverse.pythai.net/audio/ledger.txt): every rendered article, measured — duration against word count, bytes against duration, said right or said wrong.

## Use a voice

```python
from huggingface_hub import hf_hub_download
onnx = hf_hub_download("PYTHAI/voaice", "piper/en_US/ryan/high/en_US-ryan-high.onnx")
cfg  = hf_hub_download("PYTHAI/voaice", "piper/en_US/ryan/high/en_US-ryan-high.onnx.json")
# echo "Hello" | piper --model <onnx> --output_file out.wav
```

Or with voaice's own fetcher, which refuses any voice not classed open and checks every file's md5:
`python3 voaice/scripts/piper_voices_hub.py fetch en_US-ryan-high`.

## Attribution: these voices are Piper's

Every voice here was trained and published by the **Piper** project and its contributors:
[rhasspy/piper](https://github.com/rhasspy/piper) (Michael Hansen and contributors; Piper is MIT-licensed). They
are redistributed **unchanged** from [rhasspy/piper-voices](https://huggingface.co/rhasspy/piper-voices). Each voice keeps the licence of the
dataset its speakers recorded, and the original `MODEL_CARD` (dataset, licence, training notes) sits beside every
model exactly as upstream ships it. When you use a voice, credit the dataset named in its card and Piper.
See [`LICENSE.md`](LICENSE.md) (licences grouped) and [`NOTICE`](NOTICE).

## Only open licences, and why most English voices are missing

Of the 177 voices in the upstream catalogue, a voice is carried here only if **both** its own licence and,
when it is "fine-tuned from" another voice, its parent's are open: CC0, public domain, CC BY, CC BY-SA,
Apache-2.0, MIT, Unlicense or GPL/AGPL. The following are left out:

- non-commercial voices (CC BY-NC);
- the lessac / CSTR Blizzard 2013 research-only voices, and every voice **fine-tuned from lessac**, which is most of the English ones;
- voices whose licence reads only "See URL" or "Unknown".

The full classification of all 177 voices, with the licence text each decision was read from, is
[`piper-voices.json`](piper-voices.json). Copyleft voices (GPL, AGPL, CC BY-SA) keep their share-alike terms in
anything built from them. If a classification is wrong, or you hold an excluded voice whose terms allow
redistribution, open a discussion.

`piper/<locale>/<voice>/<quality>/` holds `<key>.onnx`, `<key>.onnx.json` and `MODEL_CARD`: the upstream tree minus
the language-family directory, every file matching the md5 upstream publishes in `voices.json`.
