(Android Studio)

For my Android Studio assignment, the text to speech via the "Button Read or "Read Text Below" button does not work at all as it does not say out the recorded text from the speech recognition. Please help. Pictures and description of the assignment and my code can be found below.

TLDR: The speech recognition works, but not the text to speech. The "Read Text Aloud" or you can say "Button Read" needs fixing/implementing. Take a look at my codes below.

Note: Please do not edit the XML file, leave it as it is. To test my assignment from your Android device to a Computer, plug your Android device to a computer and hit the Play Button through Android Studio. Your Android device should appear for testing. MAKE SURE TO ENABLE USB DEBUGGING on your Android device.
