I want to know how you can download different voice languages on android and later use them on IF.
Depends on the device. Check out this topic.
I have a Note 8
It says it in there, I think it will still be the same despite the topic being a bit dated.
I tried but I cant seem to open Google TTS
To actually download it on you device go into settings find language and should be in there and you should be able to get it there :)
Thanks that worked!
