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.
