—The voice to use for the TTS request. If neither voice nor audio are provided, a random voice will be used.
audio_urlURL or file—URL to the audio sample to use as a voice prompt for zero-shot TTS voice cloning. Providing a audio sample will override the voice setting. If neither voice nor audio_url are provided, a random voice will be used.
exaggerationnumber
0.25 to 2
0.5Controls emotion exaggeration. Range typically 0.25 to 2.0.
cfgnumber
0 to 1
0.5Classifier-free guidance scale (CFG) controls the conditioning factor. Range typically 0.2 to 1.0. For expressive or dramatic speech, try lower cfg values (e.g. ~0.3) and increase exaggeration to around 0.7 or higher. If the reference speaker has a fast speaking style, lowering cfg to around 0.3 can improve pacing.
high_quality_audiotrue or falsefalseIf True, the generated audio will be upscaled to 48kHz. The generation of the audio will take longer, but the quality will be higher. If False, the generated audio will be 24kHz.
seednumber (whole)
0 to …
0Useful to control the reproducibility of the generated audio. Assuming all other properties didn't change, a fixed seed should always generate the exact same audio file. Set to 0 for random seed.
temperaturenumber
0.05 to 5
0.8Controls the randomness of generation. Range typically 0.05 to 5.
