MiniMax’s high-definition text-to-speech model, Compared to Speech 02 released in May, Speech 2.6 has three major breakthroughs: stronger multilingual expressiveness, more accurate voice replication, and broader coverage with 40 languages.

Best suited for short sentence generation, voice chat, and online social scenarios. Processing is fast, but the text length is limited to less than 10,000 characters. For long-form text, we recommend using asynchronous TTS synthesis.

Request Headers

Content-Type

string

required

Supports: application/json

Authorization

string

required

Bearer authentication format, for example: Bearer {{API Key}}.

Request Body

text

string

required

The text to be synthesized. The length must be less than 10,000 characters. Use line breaks to separate paragraphs.
To control the pause duration between speech segments, insert <#x#> between words or sentences, where x is the pause duration in seconds (supports 0.01–99.99, up to two decimal places).
Custom speech pauses between text segments are supported, allowing you to control the timing of pauses in the generated audio.
Note: Pause markers must be placed between two segments that can be pronounced, and multiple consecutive pause markers are not allowed.

voice_setting

object

required

Show properties

speed

float

default:"1.0"

Range: [0.5, 2], default is 1.0Controls the speech rate of the generated audio. Optional. Higher values result in faster speech.

vol

float

default:"1.0"

Range: (0, 10], default is 1.0Controls the volume of the generated audio. Optional. Higher values result in louder audio.

pitch

int

default:"0"

Range: [-12, 12], default is 0Controls the pitch of the generated audio. Optional. 0 means original timbre. The value must be an integer.

voice_id

string

The requested timbre ID. Required (choose either this or timbre_weights).Supports both system voices (ID) and cloned voices (ID). The available system voice IDs are as follows:

Wise_Woman
Friendly_Person
Inspirational_girl
Deep_Voice_Man
Calm_Woman
Casual_Guy
Lively_Girl
Patient_Man
Young_Knight
Determined_Man
Lovely_Girl
Decent_Boy
Imposing_Manner
Elegant_Man
Abbess
Sweet_Girl_2
Exuberant_Girl

emotion

string

Controls the emotion of the synthesized speech.Currently supports 7 emotions: happy, sad, angry, fearful, disgusted, surprised, neutral.Allowed values: ["happy", "sad", "angry", "fearful", "disgusted", "surprised", "neutral"]

text_normalization

bool

default:"false"

This parameter supports English text normalization, which improves performance in number-reading scenarios, but this comes at the cost of a slight increase in latency. If not provided, the default is false.

audio_setting

object

Show properties

sample_rate

number

default:32000

Range: [8000, 16000, 22050, 24000, 32000, 44100]The sample rate of the generated audio. Optional, default is 32000.

bitrate

number

default:128000

Range: [32000, 64000, 128000, 256000]The bitrate of the generated audio. Optional, default is 128000. This parameter only applies to mp3 audio format.

format
