AzureTextToSpeech Client

This package provides a client for Azure's Cognitive Services (speech services) Text To Speech API. Users of the client can specify the lanaguage (Region type), a string containing the desired text to speak as well as the gender (Gender type) in which the audiofile should be rendered. The library fetches the audio rendered in the format of your choice (see AudioOutput types for supported formats).
