Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
audio	file	Yes	-	-	-	-	The audio file you want to transform. The words, timing, and emotion are kept. Only the voice itself changes. Audio file should be less than 5 minutes long.
voiceId	model	No	-	-	-	-	The voice you want the recording to sound like. Pick one of your own cloned ElevenLabs voices
publicVoice	string	No	Adam	-	-	Adam, Alice, Bella, Bill, Brian, Callum, Charlie, Chris, Daniel, Eric, George, Harry, Jessica, Laura, Liam, Lily, Matilda, River, Roger, Sarah, Will	One of ElevenLabs’ ready-made voices to use as the target.

styleExaggeration	number	No	-	0	1	-	How much to amplify the target voice’s style and emotion. Higher values are more expressive but can make the voice less steady. Leave empty to use the voice’s own setting.
useSpeakerBoost	boolean	No	-	-	-	-	Makes the result sound more like the chosen voice, at the cost of slightly slower processing. Leave empty to use the voice’s own setting.

Higher numbers mean better quality and larger files.
seed	number	No	-	-	-	-	An optional number that locks in the result. Reusing the same seed with the same settings produces the same audio every time; leave it empty for a fresh result on each run.
