API Endpoint

POSThttps://api.segmind.com/v1/chatterbox-turbo-tts

Parameters

reference_audiorequired

string (uri)

Provide a reference audio URL for voice matching. Use a public link for seamless access.

textrequired

string

Enter text to synthesize into speech. Use sound tags like [chuckle] for expression.

min_poptional

number

Set minimum token probability. Higher values filter out unlikely outputs.

Default: 0Range: 0 - 1

norm_loudnessoptional

boolean

Normalize audio to standard loudness. Recommended for consistent volume across outputs.

Default: true

repetition_penaltyoptional

number

Penalty for repeated words. Higher values reduce redundancy in speech.

Default: 1.3Range: 1 - 2

seedoptional

integer

Set random seed for reproducible results. Zero for random, specific value for consistency.

Default: 42

temperatureoptional

number

Adjust creativity and expressiveness in speech. Use lower for consistency, higher for diversity.

Default: 0.7Range: 0.05 - 2

top_koptional

integer

Limit to top K likely tokens. Lower for concise, higher for diverse expressions.

Default: 500Range: 0 - 1000

top_poptional

number

Control randomness via cumulative probability tokens. Lower for predictable, higher for varied outputs.

Default: 0.9Range: 0 - 1

Response Type

Returns: Audio
