# phoonnx-f5tts

ONNX exports of **F5-TTS** / **Habibi-TTS** flow-matching voices for use with
[phoonnx](https://github.com/TigreGotico/phoonnx)'s `F5TTSAdapter`
(`engine: "f5tts"`).

Each voice is exported with [DakeQQ/F5-TTS-ONNX](https://github.com/DakeQQ/F5-TTS-ONNX)
into three ONNX graphs (`model.onnx` = transformer, `F5_Preprocess.onnx`,
`F5_Decode.onnx`) plus a `config.json` and the model's `vocab.txt`.

Licensing follows the upstream model cards: **f5tts-v1-base is CC-BY-NC-4.0**
(attribution: [SWivid/F5-TTS](https://huggingface.co/SWivid/F5-TTS)); per
[SWivid/Habibi-TTS](https://huggingface.co/SWivid/Habibi-TTS) (attribution:
**SWivid/X-LANCE**), **Unified, SAU and UAE are CC-BY-NC-SA-4.0** (SADA/Mixat
restriction) while **ALG, EGY, IRQ, MAR and MSA are Apache-2.0**;
`namaa-saudi-tts-v2` is a Habibi-TTS fine-tune by **NAMAA-Space** and inherits
the CC-BY-NC-SA-4.0 restriction from its Habibi/SADA/Mixat base; `silma-tts-v1`
is an independent pretrain by **SILMA AI** and is Apache-2.0 (commercial use
OK). See each voice's own `README.md`.

This repo's top-level `license:` tag (CC-BY-NC-4.0) is the **conservative
single value** required by the Hub's metadata field — it reflects the most
restrictive checkpoint. **Always check the per-checkpoint table above before
using a specific voice commercially**; several checkpoints (MSA, EGY, ALG,
IRQ, MAR, `silma-tts-v1`) are Apache-2.0 and do not carry the NC restriction.

The Unified voice supports **dialect control** via the `dialect` engine param
(`UNK`/`MSA`/`SAU`/`UAE`/`ALG`/`IRQ`/`EGY`/`MAR`) — see its README.

## Listening samples

The [`samples/`](https://huggingface.co/OpenVoiceOS/phoonnx-f5tts/tree/main/samples)
folder has 2 wavs per voice, all synthesized through the phoonnx adapter, with
ASR round-trip intelligibility scores in
[`samples/RESULTS.md`](https://huggingface.co/OpenVoiceOS/phoonnx-f5tts/blob/main/samples/RESULTS.md)
(faster-whisper small; all 18 samples pass, CER ≤ 0.16).

## Usage

All voices are **in-context cloning** models — synthesis requires a short
reference clip and its transcription alongside the text to speak. See
[phoonnx's F5-TTS docs](https://github.com/TigreGotico/phoonnx/blob/dev/docs/f5tts.md)
for a full example (library-level and the `ovos-tts-plugin-phoonnx` config).
