Polly Immotay introduces a simple 3-step process for creating cool intros using Amazon's Polly text-to-speech service: 1) sign up for an Amazon account if needed, 2) sign up for an AWS account using a different email and password than Amazon, and 3) use the Polly text-to-speech service within AWS to type text, listen to the audio preview, and download as an MP3 file.
