Abstract

This research is aimed to analyze the comparison of the voice level through the pitch and formant identification on the Praat software. In addition, this research focuses on a simple case study that involves ten speakers of men, native and non-native, in pronouncing ten words containing vocals with the help of a PRAAT application to calculate the Pitch and Formant of speech. Technically, the research method used in obtaining a comparison of the pitch and formant of the ten speakers is descriptive-analysis by presenting data in the form of tables of numbers and graphs. This research involved one native speaker and ten non-native teacher to get comparable results. The data retrieval method uses PRAAT with audio files as the main data source. The results of this study indicate that the accuracy and the validity of comparison speakers are very low, Based on the sampling of voice data from ten speakers, it can be concluded that the value of pitch and formant are not consistent and can be applied to prove the native and non-native speaker.

Abstract

Nowadays, the advances of technology have affected all the aspects in human life, especially the existence of smartphone and computer, it is very helpful in the process of communication, education, and even forensic stuff. In this case, Praat program which can change the sound waves that used to be heard only now become visible to the human eye. In addition, the Praat program is equipped with tools to see the tone motion, the magnitude of the pause, the length of speech all of which are needed to determine the inaccuracy of an utterance or the error of the utterance. Therefore, this study is aimed to describe and to find put the utilization of praat in identifying the value of pitch and formant appropriately. This study use direct measurement method uses a laptop equipped with praat software. This method is technically based on Forensic audio method. Furthermore, the data was obtained form the audio-recorded which have derived from one native speaker and ten non-native speakers as comparison sounds. This study took ten words of Indonesian language of the utterance that has been determined by women, the results of the analysis found that in the utterance of Indonesian speakers all words consisting of some vowels and sometimes pause, sometimes there is no pause. Nevertheless, It was also found that there were differences in the presence values of pitch and formant although in the same word, vowel, and even same speakers’ gender.

Abstract

This study is aimed to analyze the measurements of pitch and formant values in determining the highest vowels which derived from the voices of native and non-native. Linguistically, this research was related to the phonetics and phonology, by applying PRAAT application to calculate the frequency and formant of speech. The subject of the study in this research was vowels contained in several Indonesian words. The focuses were only the element of pitch and formant of the fourth respondents in uttering the vowel-contained words. The research method used in This study used the Forensic audio method. However, in this study, researchers only focus on identifying pitch and formants in the data to be analyzed. In addition, the data wa descriptive analysis with the presentation of data in the form of numerical tables and graphs.

Abstract

This study is aimed to analyze the characteristics of male voices recording by using PRAAT software. Technically, this study was conducted by using direct measurement method with the assistance a laptop equipped with PRAAT software. In addition, the data were collected from the sound of men which has recorded by using a recording application which is available on smartphone that has been connected to a laptop. The sample of men voices consist one native speaker and 3 non-native speakers from the range age 22 to 30 years old. The basic frequency values ​​obtained from the voice recordings were compared between the voices of native and non-native speakers, the formant values ​​were obtained and the duration of time required in pronunciation. As result, this study found that the average basic frequency value for men (native speaker) shows a value that is almost the same as the basic frequency value for non-native speakers, it is caused by the shape of the sound-producing organs and conditions when recording sound. The value of the first formant (F1) and the fourth formant (F4) in men (native speaker) very flexible can be lower, higher and even the same to the non-native speaker. Therefore, the value of pitch and formant and the spectrum which has shown on PRAAT do not show the consistency and validity of the data so that in-depth analysis is needed with the help of other supporting media.
