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.

If you enjoy the project, please star audio.cpp on GitHub and this Hugging Face repository.

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

!!! Converted and quantized packages are checked with automated metrics, but perceived quality can still differ for human listeners. Please validate the exact package, backend, and route to confirm the output is acceptable for your use case.

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
