| exaggeration | number | Controls emotion exaggeration. Range typically 0.25 to 2.0. | 0.25 ≤ n ≤ 2 · default: 0.5 |
| high_quality_audio | boolean | If 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. | default: false |
| voice | enum | The voice to use for the TTS request. If neither voice nor audio are provided, a random voice will be used. | Aurora | Blade | Britney | Carl | Cliff | Richard · +3 more |
| audio_url | string | 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. | |
| temperature | number | Controls the randomness of generation. Range typically 0.05 to 5. | 0.05 ≤ n ≤ 5 · default: 0.8 |
| seed | integer | Useful 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. | n ≥ 0 · default: 0 |
| cfg | number | Classifier-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 speaki… | 0 ≤ n ≤ 1 · default: 0.5 |
