The Text to Speech Extension is a Scratch Extension, first added in Scratch 3.0. It has three blocks, and it allows projects which use it to output synthesized speech. It uses Amazon Web Services to provide this service.
There are five voices that can be changed with the set voice to () block:
|alto||standard female voice|
|tenor||standard male voice|
|squeak||high-pitched female voice|
|giant||deep male voice|
|kitten||just repeatedly says "meow"|
This speaks the text in the string input.
