MiniMax’s high-definition text-to-speech model, Compared to Speech 02 released in May, Speech 2.5 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 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

audio_setting

​
pronunciation_dict

timbre_weights
object[]
Required if voice_id is not provided (choose one of the two).
​
stream
boolean
default:"false"
Whether to enable streaming. Default is false, i.e., streaming is disabled.
​
language_boost
string
default:"null"
Enhances recognition of specified minor languages and dialects. Setting this parameter can improve speech performance in the specified language/dialect scenarios. If the minor language type is not clear, you can set it to “auto” and the model will automatically determine the language type. Supported values:'Chinese', 'Chinese,Yue', 'English', 'Arabic', 'Russian', 'Spanish', 'French', 'Portuguese', 'German', 'Turkish', 'Dutch', 'Ukrainian', 'Vietnamese', 'Indonesian', 'Japanese', 'Italian', 'Korean', 'Thai', 'Polish', 'Romanian', 'Greek', 'Czech', 'Finnish', 'Hindi', 'auto'
​
output_format
string
default:"hex"
Controls the output format of the result. Optional values are url and hex. The default is hex. This parameter only takes effect in non-streaming scenarios; in streaming mode, only hex format is supported. The returned URL is valid for 24 hours.

​
Response

​
audio
string
The synthesized audio segment, encoded in hex and generated in the format specified by audio_setting.format (mp3/pcm/flac). The return format is determined by the output_format parameter. When stream is true, only hex format is supported.
​
status
number
The current status of the audio stream. Returned only when stream is true. 1 indicates synthesis in progress, 2 indicates synthesis completed.
