Thanks for your support!
Do you mean only the streamer can hear the TTS? If you choose the "native" voice, you can set its output audio device(see my last reply). It is able to mute the "native" voice to audience, there is an article about how to do that.
Other built-in languages on Chrome are unchangeable and will always use the default audio output. I couldn't find any way to exclude that from the default audio.
AWESOME! Took me a while to figure out some things, but it works great now! :D [where can I leave a 5star review, new memeber here haha]
Also two questions:
1) is it possible to put the !vXXX value in the front? I have the speech rate at 9, but when trying to move it to the front so the "$username$ says" part will also be said at a faster rate, it does not apply and is just default settings
2) that web native setting uses the speech recognition but does not have/use a personality like "Microsoft David" is it possible to use that?
Thank you so much again! I really appreciate it :D
