Input schema

The fields you can use to run this model with an API. If you don't give a value for a field its default value will be used.

Field	Type	Default value	Description
text	string	Hello, this is Higgs Audio v3 TTS.	Text to synthesize. Supports inline Higgs control tokens.
sentence_pause_mode	None	off	Automatically insert Higgs pause tokens after sentence endings.
reference_audio	string		Optional reference audio for zero-shot voice cloning (WAV/MP3).
reference_text	string		Transcript of the reference audio; materially improves cloning quality.
voice	string	default	Preset voice name (ignored when reference_audio is set).
response_format	None	wav	Output audio format.
temperature	number	1 Max: 2	Sampling temperature.
top_p	number	Max: 1	Top-p (nucleus) sampling. Unset = server default.
top_k	integer		Top-k sampling. Unset = server default.
max_new_tokens	integer	2048 Min: 1 Max: 8192	Maximum number of generated multi-codebook steps.
seed	integer		Random seed for reproducibility. Unset = random.
