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.
For conversion details, supported layouts, direct-file loading, sidecar embedding, and the latest compatibility notes, see the audio.cpp GGUF guide:
!!! 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.
Files
Tested summarizes the current audio.cpp path-test status. See the GGUF guide above
for the full matrix and drift notes.

Q8 Notes
- Chatterbox Q8 is intentionally mixed type. Graph-sensitive scalar, norm, bias, and side tensors stay in non-Q8 types while matmul-compatible weights are quantized.
- PocketTTS Q8 keeps the four
flow_lm.flow_net.time_embed.*.mlp.{0,2}.weighttensors in Q8 in addition to the default converter selection.conditioner.embed,cond_embed, and Mimi conv tensors are not forced to Q8 because tested outputs drifted or the current conv path casts quantized conv weights back to F32. - Voxtral Q4_K is smaller than Q8_0 and was faster in a quick CUDA path check, with transcripts matching Q8_0 except for one capitalization-only difference.
Usage
Pass a GGUF file directly as --model:
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:
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
