If the text exceeds 3,000 characters, it is recommended to use streaming output. streambooleanOptional Controls whether to enable streaming output. Default is false, which means streaming is not enabled. stream_optionsobjectOptional exclude_aggregated_audiobooleanOptional Set whether the last chunk contains the concatenated speech hex data. The default value is False. voice_settingobjectOptional voice_idstringOptional The timbre number for synthesized audio, supports system timbres, recreated timbres, and text-to-sound timbres. speednumberOptional The speech rate of the synthesized audio, value range [0.5, 2], default value is 1.0 volnumberOptional The volume of the synthesized audio, value range (0,10], default value is 1.0 pitchintegerOptional The intonation of the synthesized audio, value range [-12,12], default value is 0 emotionenum<string>Optional Control the emotion of synthesized speech.
