Summary: | The present study is an acoustic analysis of Indian English, specifically examining the speech patterns and characteristics of three different groups with different native languages. This study investigates fundamental frequency (fo), fo range, fo variance, formant frequencies, and vowel space size in 42 native male and female speakers of Odia, Bangla, and Hindi. Furthermore, it investigated the potential correlation between fundamental frequency and vowel space, examining whether variations in vowel space size could be influenced by gender-specific perceptual factors. The paper emphasizes that in a multilingual context, gender identification can be efficiently correlated with both fo and formant frequencies. To measure a range of acoustic characteristics, speech samples were collected from the recording task. Analysis was done on PRAAT. The study revealed significant differences between genders for the examined acoustic characteristics. Results indicate differences in the size of gender-specific variations among the language groups, with females exhibiting more significant differences in fo, formant frequencies, and vowel space than males. The findings show no significant correlation between fo and vowel space area, indicating that other features are responsible for large vowel space for females. These findings display significant potential toward creating a robust empirical framework for gender profiling that can be utilized in a wide range of forensic linguistics investigations. |
