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.

Abstract

Forensic linguistics is the branch of the linguistics study which investigates legal text in crime. The aim research is to identify the suicide notes: forensic linguistic profiling analysis. The research method used cumulative sum calculation strategy for elements: SL, Pron, Prep, Ver, Adj, Adv, Conj, CSS-SL, CSS-Pron, CSS-Prep, CSS-Ver, CSS-Adj, CSS-Adv, & CSS-Conj. The program read the given texts and counted the percentage of words that reflect different emotions, thinking styles, and social concerns. The result shows that Based on the analysis of the first letter, a graph of parallel relationships is obtained between SL and CSS-SL, Pron and CSS-Pron, Ver and CSS-Ver, Adv and CSS-Adv, and Conj and CSS-Conj. Meanwhile, there are still lines that intersect in the graph of the relationship between Prep and CSS-Prep and Adj and CSS-Adj. This indicates that the first letter is genuine, considering that the number of graphs showing parallel relationships is more dominant than those with intersecting lines.
