Puttin emotions in the text prompt to make the ai talk in those emotions?

For example
[Sad] im super duper [Happy] nevermind, i am very happy!
will at first make the voice sad, then happy, when it calls for it.
using a square brackets, and in normal brackets "()" to make it whisper, or mumble if done like ([Mumbled] mumble words)

feel like this would be an awesome feature if possible, or maybe there is already a way to do it

and if possible making this accessible on https://ttsdemo.themetavoice.xyz/
