Input

Field	Kind	Default	Description
`text` required	text	—	The text to convert to speech
`voice`	text	Rachel	The voice to use for speech generation
`stability`	number 0 to 1	0.5	Voice stability (0-1)
`similarity_boost`	number 0 to 1	0.75	Similarity boost (0-1)
`style`	number 0 to 1	0	Style exaggeration (0-1)
`speed`	number 0.7 to 1.2	1	Speech speed (0.7-1.2). Values below 1.0 slow down the speech, above 1.0 speed it up. Extreme values may affect quality.
`timestamps`	true or false	false	Whether to return timestamps for each word in the generated speech
`previous_text`	text	—	The text that came before the text of the current request. Can be used to improve the speech's continuity when concatenating together multiple generations or to influence the speech's continuity in the current generation.
`next_text`	text	—	The text that comes after the text of the current request. Can be used to improve the speech's continuity when concatenating together multiple generations or to influence the speech's continuity in the current generation.
`language_code`	text	—	Language code (ISO 639-1) used to enforce a language for the model. An error will be returned if language code is not supported by the model.
`apply_text_normalization`	one of auto, on, off	auto	This parameter controls text normalization with three modes: 'auto', 'on', and 'off'. When set to 'auto', the system will automatically decide whether to apply text normalization (e.g., spelling out numbers). With 'on', text normalization will always be applied, while with 'off', it will be skipped.
