Synthesize speech
Synthesizes speech from a text string. Returns binary audio data in one of many supported audio formats. This simplified version of synthesis can be directly used in HTML5 audio tags.
Specify either speed or length, not both; otherwise a request with both will result in an 500 server error as the desired speed might not match the desired length.
For more detailed output such as the duration of each spoken word, use the Speech POST request.
