Amazon Lex now supports Amazon Polly Neural Text-to-Speech (NTTS) voices for your bots, allowing your bots to respond to your users with richer, more expressive, and natural-sounding voices than standard Polly Text-to-Speech (TTS) voices. Polly NTTS voices deliver advanced improvements in speech quality through a new machine learning approach. Amazon Lex is natively integrated with Amazon Polly for voice interactions. Until today, Lex developers could only configure bots to use Polly’s standard Text-to-Speech (TTS) voices. Starting today, you can configure bots built through Lex V2 APIs and console to use Polly NTTS voices for any language that supports an NTTS option to improve user experience and boost customer engagement.
Support for Amazon Polly NTTS voices for Amazon Lex bots is available in the following AWS Regions: US East (N. Virginia), US West (Oregon), Africa (Cape Town), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central), Europe (Frankfurt), Europe (Ireland), and Europe (London).
