This API supports synchronous text-to-speech generation, with a maximum of 10,000 characters per text submission. It supports 100+ system voices and custom cloned voices; volume, pitch, speed, and output format adjustment; proportional voice mixing and fixed interval control; and multiple audio specifications and formats, including mp3, pcm, flac, and wav. Streaming output is supported. After submitting a long-text speech synthesis request, note that the returned URL is valid for 24 hours from the time the URL is returned. Please download the information in time.
Suitable for scenarios such as short sentence generation, voice chat, and online social interaction. It has low latency, but the text length limit is less than 10,000 characters. For long text, we recommend using asynchronous speech synthesis.

Request Headers

Content-Type
string
required
Enum value: application/json
Authorization
string
required
Bearer authentication format: Bearer {{API Key}}.

Request Body

text
string
required
The text to synthesize. The length limit is less than 10,000 characters. Use newline characters to separate paragraphs. (If you need to control the interval duration in the speech, insert <#x#> between characters, where x is in seconds. Supports 0.01-99.99 with up to two decimal places.) Custom speech intervals between text segments are supported to achieve custom pause durations in the generated speech. Note that the text interval must be set between two text segments that can be pronounced, and multiple consecutive intervals cannot be set.
voice_setting
object
required
audio_setting
object
pronunciation_dict
object
timbre_weights
object[]
Required if voice_id is not specified.
stream
boolean
default:"false"
Whether to enable streaming. Default is false, meaning streaming is disabled.
stream_options
object
language_boost
string
default:"null"
Enhances recognition capability for specified low-resource languages and dialects. After setting this parameter, speech performance in the specified low-resource language/dialect scenario can be improved. If the low-resource language type is unclear, you can select “auto”, and the model will determine the low-resource language type automatically. The following values are supported:'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', 'Bulgarian', 'Danish', 'Hebrew', 'Malay', 'Persian', 'Slovak', 'Swedish', 'Croatian', 'Filipino', 'Hungarian', 'Norwegian', 'Slovenian', 'Catalan', 'Nynorsk', 'Tamil', 'Afrikaans', 'auto'
output_format
string
default:"hex"
Controls the output result format. Optional values are url and hex. Default value is hex. This parameter only takes effect in non-streaming scenarios. Streaming scenarios only support returning data in hex format. The returned URL is valid for 24 hours.
voice_modify
object
Voice effect settings. This parameter supports the following audio formats:
  • Non-streaming: mp3, wav, flac
  • Streaming: mp3

Response Information

audio
string
The synthesized audio segment, encoded in hex and generated according to the input-defined format (audio_setting.format) (mp3/pcm/flac). The returned form depends on the definition of output_format. When stream is true, only hex return format is supported.
status
number
The current audio stream status, returned only when stream is true. 1 indicates synthesis in progress, and 2 indicates synthesis has ended.
