You can aktivate the mode direktly there where you type your message in.
Now if you speak all that you are saying turns into text for the chat.
We got the idea toghether from GTimeTV: https://www.twitch.tv/gtimetv

Commands:

Commands are actions that you are saying and something than happens.

• Start: Start the speech to text.
• Stop: Stop the speech to text.
• Send: Send the text to the chat.
• Clear: Clear your text.

IMPORTANT! The command will only be executed if you don't say the word in one sentence!

For example:
If you say "please stop it" nothing happens.

But if you ONLY say "stop" then the command will be executed.

PLS VOTE!
