Version 1 of the app is completed.
I need you as a programmer to make changes for Version 2.
The current APP is a maths quiz for students that students can participate in during class with an android device.
The teacher controls the APP via bluetooth connection from the PC (Java Applet) to the android device. By clicking "trigger" on the Java Applet, the maths quiz would start on the student's android device. Version 1 of this APP is completed.
Version 2 of the APP requirements:
In the main page of the APP, there will be 3 options.
Option 1) The APP will remain the same as Version 1
Option 2) Voice activation. When the students are participating in the maths quiz, they will say the answer and the next question will appear. (The answer does not matter, however I would like to have a decibel threshold so that only talking loudly would work).
Option 3) Read Aloud. Same as option 2 but the questions will be read out loud to the students. (Screen should be black).
