How to make An app to create audio from text… using gtts

With this app you write a word, press space and the computer say it. It’s as simple as it is. I uses the google api gtts and you need to install gtts

pip install gtts

When you got a new word it will be saved in a folder. When it’s yet saved, it just plays it.

You can find the repository here: https://github.com/formazione/textspeak
