Vowel-Tone Interaction in Two Dialects of Galo Language of Arunachal Pradesh, India

Abstract

The investigation begins with an in-depth and all-encompassing assessment of the interplay between vowels and tones within the various dialects of the Galo language, notably spoken in the culturally unique enclave of Arunachal Pradesh, India - Pugo Galo and Lare Galo. Our research aims to shed light on the numerous phonological nuances seen in these languages. We concentrate on a range of acoustic characteristics related to vowels. We investigate the fundamental frequency (F0) and formant frequencies (F1 and F2), which have a substantial impact on the various phonetic properties of spoken language. Our goal is to understand the fundamental variables that drive the interplay between vowels and tones while accounting for gender and dialect differences through meticulous data collection and rigorous statistical analysis. With its mosaic of dialects, the Galo language provides a stimulating linguistic field for investigation. Our research is motivated by a desire to uncover the subtle variations and trends that highlight the linguistic variety found in the Galo community. The focus of our analysis is on F1 and F2 values, fundamental frequency (F0), and vowel length. These acoustic factors are critical for understanding the phonetic differences between Pugo Galo and Lare Galo, as well as probable gender- related variants within these dialects. We provide an extensive analysis of the collected data using statistical approaches, allowing us to establish meaningful comparisons and highlight the different linguistic features that characterize these two Galo dialects. In essence, our findings not only contribute to the vast area of linguistics, but also provide essential insights into the protection and appreciation of linguistic variety within the Galo community.
