Abstract:
Voice command based applications use speech to
make people’s life more easy and flexible. It is one of the most
interesting topics in recent research spheres and still there are
lots of scope for improvement. The paper represents the method
of controlling electrical components by Matlab graphical user
interface (GUI) using voice command. The idea of developing
voice controlled application can be established through speech
identification and speech verification. Speech identification is
performed by feature extracting of speech signal utilizing Mel
Frequency Cepstrum Coefficient (MFCC) technique in Matlab.
Then vector quantization (VQ) method has been proposed
for verification. The recognized speech will be compared with
prerecorded database and according to those results the desired
commands are sent from application to microcontroller to control
the devices.
