Abstract :
Voice is one of way to communicate and express yourself. Speaker
recognition is a process carried out by a device to recognize the speaker through
the voice. This study designed a speaker recognition system that was able to identify
speakers based on what was said by using dynamic time warping (DTW) method
based in matlab.
To design a speaker recognition system begins with the process of
reference data and test data. Both processes have the same process, which starts
with sound recording, preprocessing, and feature extraction. In this system, the
Fast Fourier Transform (FFT) method is used to extract the features. The results
of the feature extraction process from the two data will be compared using the DTW
method. Calculations using DTW that produce the smallest value will be
determined as the output.
The test results show that the system can identify the voice with the best
level of recognition accuracy of 90%, and the average recognition accuracy of
80%. The results were obtained from 50 tests, carried out by 5 people consisting of
3 men and 2 women, each speaker said a predetermined word
