Speech content supplied as text; the reference speaker provides the voice used to render it.

Voice-cloning source supplied as an audio file URL, identifying the speaker whose vocal characteristics the model should reproduce.

Advanced output_format · transcript · language · num_extra_steps · temperature · top_p · repetition_penalty · acoustic_cfg_scale · noise_temperature · num_inference_steps · speed_up_factor · enable_safety_checker
output_format default wav

File format for the generated audio.

default

Reference-audio transcript that must be supplied for recordings in languages other than English; automatic transcription is built in for English only.

default en

Text-alignment language code, which must correspond to the synthesis language when generating speech in a language other than English.

default 0

Extra autoregressive step count for adding trailing prosody or silence by continuing speech past the supplied text.

default 0.6

Text-token sampling temperature: increasing it adds output variety, and 0 or lower is not permitted.

default 0.9

Top-p (nucleus) sampling setting used to generate text.

default 1.1

Penalty for token repetition while generating output.

default 1.6

Classifier-free guidance strength used to generate acoustic features.

default 0.9

Noise temperature used during flow-matching diffusion.

default 20

ODE solver step count used to generate acoustics through flow matching.

default 1

Speech-speed multiplier: generated speech becomes slower below 1.0 and faster above 1.0.

About Tada

Clones a speaker from a reference clip (`audio_url`) and reads the `prompt` text in that voice. The `language` option accepts en, ar, ch, de, es, fr, it, ja, pl and pt. For non-English references, supply a `transcript`, because the built-in recognition is English-only. Speed can be scaled from 0.5 to 2, and output is wav or mp3.

Parameters

Send either the canonical name or the native name, not both. Canonical names
