Audio8-TTS-Preview-0.6b-GGUF

GGUF conversion of Audio8/Audio8-TTS-Preview-0.6b for audio.cpp . No new training.

Original checkpoint: 0.6B DualAR — Slow 24×896 (14 heads, 2 KV), Fast 4×896, 10×4096 codebooks, 44.1 kHz codec (2048 samples/frame), 2048 context. Languages: yue/zh/nl/en/fr/de/it/ja/ko/pl/es/auto. See original model card for details and evaluation.

File

Both embed config.json , tokenizer.json , tokenizer_config.json and model_specs/audio8_tts.json . q8_0 is the recommended default.

Conversion

• Source: model.safetensors + codec.safetensors from Audio8/Audio8-TTS-Preview-0.6b
• Tool: convert_audio8_tts.py + audiocpp_gguf ( --family audio8_tts --model-spec model_specs/audio8_tts.json --type q8_0/bf16 )
• Change: storage type/quantization only (q8_0). No architecture or training changes.

Usage (audio.cpp)

# offline TTS
audiocpp_cli --task tts --family audio8_tts \
  --model audio8-tts-preview-0.6b-q8_0.gguf \
  --text "The quick brown fox jumps over the lazy dog." --out out.wav

# streaming + voice cloning
audiocpp_cli --task tts --mode streaming --family audio8_tts \
  --model audio8-tts-preview-0.6b-q8_0.gguf \
  --text "Hello world" --voice-ref ref.wav --reference-text "transcript of ref.wav" --out out.wav
