# MiniMax Speech-2.6-turbo Synchronous Text-to-Speech

This API supports synchronous text-to-speech generation, with a maximum of 10,000 characters per request. Supports 100+ system voices and cloned voices; supports volume, pitch, speed, and output format adjustments; supports proportional voice mixing and fixed interval time control; supports multiple audio specifications and formats including: mp3, pcm, flac, wav, and streaming output.

After submitting a long text speech synthesis request, please note that the returned URL is valid for 24 hours from the time it is returned. Please be mindful of the download timing.

<Tip>Suitable for short sentence generation, voice chat, online social scenarios, with low latency but a text length limit of less than 10,000 characters. For long texts, it is recommended to use [Async Text-to-Speech](/docs/models/reference-minimax-speech-2.6-turbo-async).</Tip>

## Request Body

<ParamField body="text" type="string" required={true}>
  The text to be synthesized, length limit less than 10,000 characters. Use newline characters for paragraph breaks. (To control the pause duration in the speech, insert \<#x#> between characters, where x is in seconds, supporting 0.01-99.99 with up to two decimal places). Supports custom time intervals between text segments to achieve custom speech pause durations. Note that the interval must be set between two text segments that can be vocalized, and multiple consecutive intervals cannot be set.

## Response

<ResponseField name="audio" type="string">
  The synthesized audio segment, hex-encoded, generated in the format defined by the input (`audio_setting.format`) (mp3/pcm/flac). The return format is determined by the `output_format` setting. When `stream` is true, only hex format is supported.
