MATLAB voice recognition coding

timer Asked: May 1st, 2016

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 spectrum

3) Compare spectrum of voice commands

for 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 )

please refer to the pdf for more details
