What is Cloud Text-to-Speech?
Google Cloud Text-to-Speech converts text into human-like speech in more than 100 voices across 20+ languages and variants. It applies groundbreaking research in speech synthesis (WaveNet) and Google's powerful neural networks to deliver high-fidelity audio. With this easy-to-use API, you can create lifelike interactions with your users that transform customer service, device interaction, and other applications.
Google's Google Assistant uses the same API for turning text into speech. Take a listen to the sample:

Since it is an API, this means that this library can be platform independent, delivering the higher quality voices for 20+ languages at no additional installation on any device.
Installation:
1. Place CloudTTS.b4xlib in your additional libraries folder
2. Go to https://console.cloud.google.com/apis/api/texttospeech.googleapis.com and enable Cloud Text to speech API
3. Go to "Credentials" and generate an API key
this API key will be used in the code:
Usage:
Using the library is pretty simple:
