A new generative engine and three voices are now generally available on Amazon Polly

Amazon Polly now offers a new generative engine with three voices: Ruth and Matthew in American English and Amy in British English. The generative engine uses publicly available and proprietary data to produce high-quality, context-dependent speech. Amazon Polly is a machine learning service that converts text to lifelike speech and offers various voice options, including neural, long-form, and generative voices.
