# Gooya Bozorg v1.5

**Gooya Bozorg v1.5** is the versioned PersianASR distribution of
[`Thomcles/Chatterbox-TTS-Persian-Farsi`](https://huggingface.co/Thomcles/Chatterbox-TTS-Persian-Farsi),
a Persian fine-tune of Resemble AI's 500M multilingual Chatterbox TTS model.

This release preserves the selected upstream checkpoint exactly. We did **not**
claim additional training or altered weights: it was promoted after a controlled
listening comparison against our own 227,753-clip step-3500 fine-tune, where the
upstream Persian checkpoint retained slightly better pronunciation and pacing.
The weight hashes are recorded in `MODEL_MANIFEST.json`.

## Why “Bozorg”?

This is the larger, higher-quality Gooya lane. It prioritizes Persian speech
quality and zero-shot voice cloning over the footprint of Gooya's small/on-device
models.

## Quick start

Install the official Chatterbox repository and the small runtime dependencies:

```bash
git clone https://github.com/resemble-ai/chatterbox.git
cd chatterbox
pip install -e .
pip install huggingface_hub safetensors soundfile
```

Then download this repository and run:

```bash
python inference.py \
  --model-dir /path/to/Gooya-Bozorg-v1.5 \
  --text "سلام، حالت چطوره؟" \
  --reference /path/to/reference.wav \
  --output gooya-bozorg.wav
```

The reference should be a clean single-speaker WAV. The defaults match the
comparison run: `exaggeration=0.5` and `cfg_weight=0.5`.

## Included comparison samples

- `samples/canonical.wav`: conversational Persian pronunciation
- `samples/conversational.wav`: punctuation and dialogue-like pacing
- `samples/codeswitch.wav`: mixed Persian and English terms

All three were generated with fixed seeds and the same reference/settings used
for the competing Gooya checkpoint.

## Provenance

- Upstream model: `Thomcles/Chatterbox-TTS-Persian-Farsi`
- Pinned upstream snapshot: `4e9f6b7043d30d8328bb842b6126676bead8d9de`
- Architecture/runtime: `ResembleAI/chatterbox`
- Weight status: byte-identical repackaging of the selected upstream files
- PersianASR release name: Gooya Bozorg v1.5

Credit for the Persian training and original release belongs to **Thomcles**.
Credit for Chatterbox belongs to **Resemble AI**.

## Limitations

- This model can still mispronounce ambiguous Persian words and mixed-script text.
- Pacing and question intonation are improved relative to our tested fine-tune,
  but are not fully controllable.
- Output quality depends strongly on the reference clip.
- This release is not a tiny/on-device model and needs substantially more memory
  than Gooya's small models.
- The license is non-commercial; review it before deployment.
