The Talk For Me app helps you talk in every day life and allows you to participate in meetings/encounters even if you can't talk the biological way.
It might even allow you to not always carry your clunky speech computer or it might just help you to talk to your brother after your wisdom teeth got removed ;)
The always visible buttons at the top allow you to always say the important things if you need to. The history allows you to repeat your self or edit spoken texts.
If you turn on the Auto Talk function, it even talks while you write!
