This API supports synchronous text-to-speech (TTS) generation, with a maximum input length of 10,000 characters per request. It offers over 100 system and cloned voices, with customizable parameters including volume, pitch, speed, and output format. The API supports proportional voice mixing, fixed interval control, and multiple audio formats such as mp3, pcm, flac, and wav. Streaming output is also supported.When submitting a long-text TTS request, please note that the returned audio URL is valid for 24 hours from the time it is generated. Be sure to download the audio within this period.
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.
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.
The requested timbre ID. Required (choose either this or timber_weights).Supports both system voices (ID) and cloned voices (ID). The available system voice IDs are as follows:
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.
Replacement of text, symbols and corresponding pronunciations that require manual handling.
Replace the pronunciation (adjust the tone/replace the pronunciation of other characters) using the following format:[“omg/oh my god”]For Chinese texts, tones are replaced by numbers, with 1 for the first tone (high), 2 for the second tone (rising), 3 for the third tone (low/dipping), 4 for the fourth tone (falling), and 5 for the fifth tone (neutral).
Range: [1, 100]The weight, must be provided together with voice_id. Up to 4 timbres can be mixed. The value must be an integer. The higher the proportion for a single timbre, the more the synthesized voice will resemble it.
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'
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.
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.
Below is an example of how to use the Minimax Speech-02-turbo synchronous API.
Non-streaming (stream is false)
If output_format is not set to url, the default return format is hex.
