Twilio has announced that it now supports Amazon Polly, adding over 50 voices, 25 languages, and new APIs to its Programmable Voice applications. This integration allows developers to control synthesized speech output, including volume, pitch, rate, and pronunciation, giving them more control over interactive voice applications. With the built-in Basic TTS supported by Twilio now being replaced by Amazon Polly, developers can choose from a vast selection of voices and customize their application's text-to-speech behavior with ease. The integration also includes features such as central management through the Twilio Console and support for SSML, allowing developers to create more lifelike speech experiences. Pricing starts at $0.0008 per 100 spoken characters, and Twilio plans to continue adding new voices and features in the future.
