Question description
the method weve come up with so far is as follows: 1) Record voice command (Time domain)2) Transform into frequency domain using
Fourier Transform and get the magnitude spectrum3) Compare spectrum of voice commandsfor the effects the following codes can be used:for slow and slower we use: sound(y,Fs/4)for faster and faster we use: sound(y,Fs*4)for turn around we use flip: sound(flip(y),Fs)For play tone we use: sound(y(1:4000*0.5),4000 )
