This API supports asynchronous text-to-speech generation. A single text generation request supports up to 1 million characters for transmission, and the complete generated audio result can be retrieved asynchronously. It supports 100+ system voices and custom cloned voices; it also supports custom adjustment of intonation, speed, volume, bitrate, sample rate, and output format. 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 generating speech from long texts such as entire books. Task queueing may take a relatively long time. For scenarios such as short sentence generation, voice chat, and online social networking, we recommend using synchronous speech synthesis.
