MSA Speech Rhythm Pattern in a Multilingual Setting

Abstract

This study examines variation in rhythm metrics in a multilingual setting by focusing on between-speaker differences. The investigation analyzes speech rhythm patterns of segmental durations in the speech of 77 Algerian speakers belonging to three educational background classes and three age groups. The experiment focuses on speech rhythm variability according to the level of educational background of the speakers and the language used in daily life. The gender and age of speakers are also analyzed. Results show that five vocalic rhythm metrics reflect the contrast between long and short vowels that was observed from the acoustic measurements. The statistical analysis reveals that rhythm metrics are sensitive to differences between groups of speakers, such as age and educational background. The outcomes also show that the lack of practice of Modern Standard Arabic by some speaker groups considerably affects vowel quantity.
