| # Fish Speech — PT-BR Fine-tuning (Paraíba Accent) |
|
|
| LoRA fine-tuning of **Fish Speech 1.5** ([fishaudio/fish-speech-1.5](https://huggingface.co/fishaudio/fish-speech-1.5), LLaMA component) on the PT-BR corpus `PB_PARAIBA` (May 2026). Checkpoints and configs at the root; `graficos/` with curves and metrics; `inferencias/` with evaluation audio. |
|
|
| ## Checkpoints |
|
|
| | Path | Description | |
| |---|---| |
| | `final_merged_llama/` | Final model with LoRA merged (`model.pth` + tokenizer) — **use this for inference** | |
| | `merged_step_000010488/` | Merge of the checkpoint at step 10,488 | |
| | `lora_step_000010488.ckpt` | Raw LoRA checkpoint (Lightning) | |
|
|
| ## Training |
|
|
| | Parameter | Value | |
| |---|---| |
| | Base model | fish-speech-1.5 | |
| | Steps | 10,488 (1 synthetic epoch) | |
| | Training time | ~44.7 h | |
| | Config | `training_config.yaml` | |
|
|
| ## Files |
|
|
| - `graficos/` — train/eval loss curves and timing (PNG + CSV) |
| - `inferencias/` — `baseline_phrase_*.wav` × `step_000010488_phrase_*.wav` (baseline vs. fine-tuned), `reference_prompt.wav` + transcript, and `synthesis_phrases_ptbr.txt` |
| - `machine_profile.json`, `timing_*.json`, `dataset_text_stats.json` — environment, timing, and dataset stats |
|
|
| ## Usage |
|
|
| Use `final_merged_llama/` as the LLaMA weights directory in the official [Fish Speech](https://github.com/fishaudio/fish-speech) pipeline. |
