AWS Polly

AWS Polly is a deep-learning Text-to-Speech (TTS) service: it converts text into lifelike, streaming audio.

Polly is your go-to, fully-managed TTS solution: it uses advanced deep learning to synthesize natural human speech. The service offers over 100 voices across 40+ languages, providing global reach and accessibility. Leverage Neural Text-to-Speech (NTTS) for highly expressive, human-like quality, ideal for long-form content like audiobooks. You get granular control via Speech Synthesis Markup Language (SSML) to adjust pitch, speed, and pronunciation (using custom lexicons). Output is delivered as an audio stream or stored in standard formats (MP3, OGG) for integration into mobile apps, IoT devices, or contact center solutions.
