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.

The text to convert to speech. Maximum 2,000 characters. Supports SSML break tags for pauses (e.g. `<break time="1s" />`), emotion markups (e.g. `[happy]`, `[sad]`), and non-verbal vocalizations (e.g. `[laugh]`, `[sigh]`).
voice_id
string
Ashley
The voice to use. Use a preset voice name (e.g. 'Ashley', 'Dennis', 'Alex') or a custom cloned voice ID.

None
mp3
Output audio format.
sample_rate
None
48000
Audio sample rate in Hz.
speaking_rate
number
0

Max: 1.5

Speaking speed multiplier. Set to 0 for normal speed (1.0).
