How to change the speaker voice

The speaker parameter lets you choose a specific voice for the speech output.

Speaker Selection

Specify the speaker using the speaker parameter in your request. It is an optional parameter — if omitted, the API uses the default voice (Shubh for bulbul:v3, Anushka for bulbul:v2).
