| # DIO Piper FA |
|
|
| Pinned Persian Piper model used by DIO Voice. This release redistributes the |
| accepted Mana Persian Piper ONNX artifact unchanged; it is not the rejected |
| DIO prosody experiment. |
|
|
| ## Files |
|
|
| - `fa_IR-dio-piper-fa.onnx`: Piper medium ONNX model. |
| - `fa_IR-dio-piper-fa.onnx.json`: Piper voice configuration. |
| - `sample-fa.mp3`: generated Persian sample. |
| - `SHA256SUMS`: release integrity hashes. |
|
|
| ## Provenance |
|
|
| - Source model: `MahtaFetrat/Mana-Persian-Piper`, commit |
| `ad9dd8518bedf517bd7cbc9f63b8e5c844bf5bc0`. |
| - Source model license declared by its model card: MIT. |
| - Training dataset: `MahtaFetrat/Mana-TTS`, declared CC0-1.0. |
| - Architecture lineage: Piper / VITS. |
|
|
| The DIO runtime adds a separate context-aware Persian phonemization stage. Its |
| GPL source and exact patches are distributed with the `dio-voice` source |
| release; those components are not embedded in this model repository. |
|
|
| ## Use |
|
|
| Load the ONNX file with a compatible Piper runtime and its adjacent JSON |
| configuration. DIO Voice pins this repository by immutable Hub commit and |
| SHA-256; end-user installation does not require Hugging Face CLI or login. |
|
|
| ## Evaluation and limitations |
|
|
| The artifact passed DIO's synthesis/PCM integration smoke check at 22,050 Hz. |
| No MOS, WER, speaker-similarity, or demographic benchmark is claimed. Persian |
| pronunciation and prosody remain dependent on input normalization and |
| phonemization. See `METRICS.md` for the release gate and known limits. |
|
|
| The experimental tail-locked checkpoint was excluded because it failed its |
| own prosody separation gate (`+0.72 st` and `+5.62 st/s` question-vs-statement |
| tail separation). This repository therefore makes no claim that DIO trained |
| or improved the acoustic weights. |

| ## Attribution |

|
| Model authors and dataset contributors retain their original attribution. |
| DIO Voice packages the pinned artifact for portable inference. |
