Amazon Polly – Text-to-Speech

Amazon Polly supports dozens of languages and a wide selection of natural-sounding male and female voices. When you send text to Amazon Polly's API, it returns the audio to your application as a stream so you can play the voices immediately. Amazon Polly also supports lexicons and SSML tags which enable you to control aspects of speech, such as pronunciation, volume, pitch, and speed rate,
