Updated to Android Studio version
This application simply displays the words that it hears on the screen in large letters.
It was written as an aid to communication with deaf people. I have shared it here just in case other people find it useful.
The size of the font can be configured.
It continually listens and displays text when a sentence has finished. As with all apps that use the Google speech recognition service, it is better to speak slowly and clearly.
V1.61 - First release of non advert supported version.
