Plotting voice from BT input

Hello! I have a question. Currently I am doing a project that can use voice as a light switch. I am using MIT App inventor for the speech recognition and it is connected to arduino uno via HC 06 bluetooth module. It is already working but I need to make a waveform of the output. Please help :<

Hello may I ask, can I plot the speech from the app to the serial plotter?
