# audio.cpp GGUF Model Packages

This directory contains audio.cpp-native GGUF conversions of multiple speech models. These files are intended for use with [audio.cpp](https://github.com/0xShug0/audio.cpp).

For conversion details, supported layouts, direct-file loading, sidecar embedding, and the latest compatibility notes, see the audio.cpp GGUF guide:

- https://github.com/0xShug0/audio.cpp/blob/main/docs/gguf.md

!!! Automated audio checks are intentionally strict and may flag length, log-mel, or transcript drift that can still sound acceptable to human listeners. Validate the exact file, backend, and route you plan to use. These converted weights are provided as-is; use them at your own risk.

## Usage

Pass a GGUF file directly as `--model`:

```bash
audiocpp_cli --task tts --family supertonic --model Supertonic-3-GGUF/supertonic-3-orig.gguf --backend cuda --language en --text "Hello." --voice-id M1 --out out.wav
```

For ASR:

```bash
audiocpp_cli --task asr --family qwen3_asr --model Qwen3-ASR-0.6B-GGUF/qwen3-asr-0.6b-f16.gguf --backend cuda --audio speech.wav --text "" --text-out transcript.txt
```
