Hearing Helper is a quick and accurate way of communicating with someone using text. You can use your voice (voice typing) or keyboard to input the text. It can also be a handy backup communication app for people who wear hearing aids. The app doesn't require an Internet connection and can be used with the many languages supported by your Android device/keyboard.
Moreover, the app can also be used to speak to someone in a different language when used with Google's keyboard (Gboard) translate feature.
Improvements/new features are ongoing.
