MiniMax | SignalWire

MiniMax is a text-to-speech engine offering expressive voices across many languages, with controls for emotion, speed, pitch, and volume.

Models

SignalWire supports the following MiniMax models. Pick a turbo model for speed and cost, or an hd model for the highest quality. If you don’t specify a model, speech-2.6-turbo is used.

Model	Description
`speech-2.6-turbo`	Default. Latest turbo model: faster and lower-cost
`speech-2.6-hd`	Latest HD model: higher quality
`speech-02-turbo`	Previous-generation turbo model
`speech-02-hd`	Previous-generation HD model
`speech-01-turbo`	First-generation turbo model
`speech-01-hd`	First-generation HD model

Voices

Press play to audition any MiniMax voice, then copy config to grab the value for SWML or your SDK.

MiniMax provides a large library of system voices across many languages. A voice’s Voice ID is what you put in the voice string: for example, English_CalmWoman becomes minimax.English_CalmWoman.

Only MiniMax’s built-in system voices are supported. Cloned and AI-generated voices do not work — you must use one of the default voice IDs that MiniMax provides.

Some voice IDs contain spaces or parentheses (for example, Cantonese_ProfessionalHost (F)). Wrap the whole voice string in quotes when a voice ID isn’t a plain word, for example voice: "minimax.Cantonese_ProfessionalHost (F):speech-2.6-turbo".

Usage

A voice identifier string has three parts: the minimax engine code, a voice ID, and an optional model.

Format: minimax.<voiceId>:<model>

voiceId (required): a MiniMax system voice ID (for example, English_CalmWoman); see Voices.
model (optional): one of the models above. Defaults to speech-2.6-turbo.

Examples:

minimax.English_CalmWoman:speech-2.6-turbo
minimax.English_Trustworth_Man:speech-2.6-hd
minimax.Japanese_KindLady:speech-2.6-turbo

You can also set the model with the separate model parameter of the languages SWML method instead of appending :model to the voice string:

1 languages:
2 - name: English
3   code: en-US
4   voice: minimax.English_CalmWoman
5   model: speech-2.6-turbo
