Analyzing acoustic patterns of vowel sounds produced by native Rangri speakers

The foundational-cum-descriptive study aims to document Rangri vowel realizations acoustically. The Rangri is a member of the Indo-Aryan language family. Ranghar Muhajir of Pakistani Punjab and some parts of Sindh speak Rangri-a zero-resource dialect of Haryanvi. Analyzing native Rangri speakers’ vowels phonetically is the purpose of the current investigation. Native speakers of Rangri recorded their voice samples. Information about the acoustic realizations of Rangri vowels produced by native Rangri speakers is the primary goal of the study. A few words in IPA transcription—[sɪr, mi:, hʊɳ, ʤeɳ, bʰɜːɽ, ʧɔːl, kæy, kʌdʰ, ɡuːɳ, and roʤ]—have ten vowel sounds incorporated in them, reflecting their production and perception in Rangri speech. The vowel sounds: /ɪ/, /i: /, /e/, /o/, /u: /, /ʊ/, /ɜː/, /ɔː/, /æ/, /ʌ/ were recognized as monophthongs. The current investigation identifies 180 voice samples total-10 vowels × 6 speakers × 3 repetitions. A high-quality Android smartphone was used for each recording, thus there was almost no background noise. The four parameters that were included for the analysis were F0, F1, F2, and duration. Pitch is measured with F0, tongue height with F1, vowel back-ness with F2, and vowel length with duration. The recorded voice samples were analyzed using Praat Speech Recognition software. With the exception of six native speakers, this study adds to our knowledge of the phonetic characteristics of Rangri and exposes the intricacies of this distinctive dialect.
