I check the list but does not find Amazon Polly listed: https://cdn.discordapp.com/attachments/1383034031951839273/1383034032098508903/image.png?ex=684d5250&is=684c00d0&hm=c27497865cfb4d9bc5672b257e98c707e29657a1d70e91a9fe4b3180138abba2&

Amazon Polly is not currently listed as a supported TTS provider in Vapi. The official documentation only lists providers such as Vapi, Cartesia, ElevenLabs, Rime AI, PlayHT, LMNT, Deepgram, OpenAI, Azure, Neuphonic, and Smallest AI. If you need Amazon Polly support, you may want to explore Vapi's custom TTS integration options, but there is no official documentation for Polly integration at this time.
