PPT PageUp and PageDown based on voice command

Say "right" or "left" to your microphone, and PPT slides will PageUp and PageDown. right - next page left - previous page

In this project, Simulink is used. Audio Device block to get signal from microphone. MATLAB Function block to convert signal into freq-domain. Deep Learning Network is used to recognise command. Function-call subsystem blocks are generated from Python and will control keyboard to press "N" and "P", which means PageUp and PageDown for PPT.

Please note, the Deep Learning Network is from MATLAB shipping demo, and it supports 10 different voice commands. Only two of them are used in this project.

How to use

1.install python. I am using version 3.11. Other supported version should work

2.install pyautogui

3.in MATLAB (r2024a or later), double click .mlproj file to extract the Simulink project

4.open test_model.slx and run it

5.open PPT and play slides

6.say "left" for pre-page and "right" for next-page
