Paper Title
Speech Recognition System using MFCC and DTW
Abstract
This paper presents a speech recognition system. The main goal of this system is to classify the speech of the
speaker. In this system, there are three main parts – (1) pre-processing, (2) feature extractions and (3) classification. The
input speech is preprocessed by Voice Active Detection (VAD).Features are extracted by Mel-Frequency Cepstral
Coefficient (MFCC). The input speech is classified by Dynamic Time Wrapping (DTW). There are five types of speech
objects and 32 speech signals for each object. The system is processed for both user-dependent and user-independent. The
overall accuracy of training data testing is 100 % for both. However, the accuracy of the real-time data testing is 44 % and52
% for user-dependent and user-independent, respectively. Therefore, user-independent system is more accuracy and less
error rate than user-independent one.
