Today, we are excited to announce the general availability of the highly expressive generative engine with the three English Amazon Polly voices: two American English voices, Ruth and Matthew, and one British English voice Amy. 

Amazon Polly is a service that turns text into lifelike speech, allowing you to create applications that talk and to build speech-enabled products depending on your business needs.

The generative engine is Amazon Polly's most advanced text-to-speech (TTS) model. It has been trained with a variety of voices, languages, and styles. It performs with the high precision to render context-dependent prosody, pausing, spelling, dialectal properties, foreign word pronunciation, and more. Generative synthetic voices are emotionally engaged, assertive, and highly colloquial in a way that makes them remarkably similar to human voice. We ensured that despite the powerful abilities of the new voices, they are also suitable for low latency online conversational use-cases. Our customers can use a generative voice persona as a knowledgeable customer assistant, a virtual trainer, or an advertiser with a near-human synthetic speech.

Ruth, Matthew, and Amy generative voices are accessible in the US East (North Virginia) region and complement the other English voices that are already available for developing speech products for a variety of use cases.
