Real-Time Speech Recognition System

Mitchel Weintraub

Abstract:

The purpose of this project is to develop a real time speech recognition system. The
function of this speech recognition system is to the system unlock upon recognizing a
voice password spoken by administrator or password holder. This project highlights the
development of speech recognition using Matlab 7.0 to recognize the input speech. This
system can be used as a security system such as Verification for Assessing Entry
Application and Password Substitutions. The main objective of this project is to design
the voice recognition system. Analysis of the voice is made using correlation and the
regression method to compare the voiceprint of different words. These techniques
provide stronger ability to recognize the same word. Voice training session is very
important for the system to identify accurate frequency spectrum for one word. The
training procedure is also used to reduce the random changes due to one word is spoken
different times. The experimental results demonstrate high accuracy for this real time
voice recognition system.
