MOSS-TTS-Local

MOSS-TTS-Local is the larger local-transformer path.

Field	Value
Family	moss_tts_local
Model directory	models/MOSS-TTS-Local-Transformer-v1.5
Codec layout	Bundled in standalone GGUFs; original checkpoints require audio_tokenizer/ inside the model root
Task	tts, clon
Modes	offline
Languages	Model auto-handles supported languages; --language can pass a language hint
Voice input	Optional reference WAV through --voice-ref; Local does not consume a reference transcript
Built-in voices	Not exposed

Text-only speech:

audiocpp_cli --task tts --family moss_tts_local --model /path/to/MOSS-TTS-Local-Transformer-v1.5 --backend cuda --text "Hello from MOSS-TTS-Local." --out out.wav

Voice clone:

audiocpp_cli --task clon --family moss_tts_local --model /path/to/MOSS-TTS-Local-Transformer-v1.5 --backend cuda --text "Hello from MOSS-TTS-Local." --voice-ref /path/to/reference.wav --out out.wav

--max-tokens	integer	4096	Maximum generated audio frames.
--do-sample	true, false	true	Enable stochastic audio-token sampling.
--temperature	float	1.7	Audio-token sampling temperature.
--top-p	float	0.8	Audio-token nucleus sampling limit.
--top-k	integer	25	Audio-token top-k sampling limit.
--repetition-penalty	float	1.0	Audio-token repetition penalty.
--text-chunk-size	characters	2048	Framework long-form text chunk size.
--text-chunk-mode	default, tag_aware, japanese, endline	default	Framework long-form text chunking mode.
