Voice command based Matlab GUI for microcontroller

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.
