Feature request - emotion & ssml for indic languages

[deepcode-debug]

🚀 Feature

The ssml doesn't work for indic languages as well as emotion control

Motivation

To generate controllable emotional speech

Pitch

The tts would be very much useful if ssml and some configurable emotional speech generation is supported.

A cool feature for the future, but we are still struggling with this even for base languages.
