Chapter 40 Analysis of Fundamental Frequency and Formant Frequency for Speaker 'Makhraj' Pronunciation with DTW Method

摘要

This article aims to look at the similarities and differences in the fundamental frequency and formant frequencies using the autocorrelation function and LPC function in GUI MATLAB 2012b on sound hijaiyah letters for adult male speaker beginner and expert based on makhraj pronunciation and both of speaker will be analyzed on the matching distance of the sound use DTW method on cepstrum. Subject of speech beginner for makhraj pronunciation are taken from college students of Universitas Gunadarma aged 22 years old. Data of the speech beginner for makhraj pronunciation is recorded using MATLAB algorithm on GUI. Subject of speech expert for makhraj pronunciation are taken from previous research. They are 20-30 years old from the time of taking data. The sound will be extracted to get the value of the fundamental frequency and formant frequency. After getting both frequencies, analysis will be obtained of the similarities and differences in the fundamental frequency and formant frequencies of speech beginner and expert and it will show the matching distance of both speech. The result is, all of speech beginner's and expert's based on makhraj pronunciation have different values of fundamental frequency and formant frequency. Then the results of the matching distance analysis using DTW method showed that there is no identical similarity between speech beginner's and expert's based on makhraj pronunciation.
