Options

style

string

Speaking style, e.g. Conversational. Defaults to Conversational. The available styles differ per voice — a style one voice supports may be rejected or ignored for another, so check the voice in Murf’s library.

rate

number

Speaking rate. Defaults to 0, which is the voice’s natural pace. Positive values are faster, negative slower.

pitch

number

Pitch adjustment. Defaults to the voice’s natural pitch.

variation

number

How much prosody varies between sentences. Higher values sound less uniform across a long prompt.

Endpoint override

Murf credentials accept an optional API base URL in the portal, for customers pointed at a non-default Murf endpoint. Leave it blank to use Murf’s standard API.

Streaming

Murf supports TTS streaming.
