Abstract

Scientific study of speech rhythm for more than eight decades proves that it is not only an important part of music and poetry, but has become a challenging subject in all branches of linguistics. Moreover, acoustic study of speech rhythm has provided practical results in various topics, including speaker identification. On the other hand, some studies indicate that speech rhythm varies greatly between languages, dialects and speakers. They concluded that the between-speaker variations in speech rhythm depends on the linguistic discriminations in the sentences. In this study, in addition to examining Qashqai speech rhythm, the effect of each sentence on the rhythmic features of this linguistic dialect was investigated. To this end, the acoustic durational rhythmic correlations of Qashqai in a reading text were examined by calculating different measures of phonetic intervals including segmental intervals, vowel and consonant intervals, vocalic and intervocalic intervals, voiced and unvoiced intervals, syllable intervals, and syllable peaks intervals. Furthermore, in order to study the effect of each sentence on Qashqai rhythmic features, between-sentence speech variability was considered. The results showed that Qashqai rhythm was placed in the middle the rhythm continuum of languages close to the syllable-time languages; however, in comparison to Persian language it was closer to the stress-time languages. The results of durational rhythmic measures at different phonetic intervals demonstrated that the Syllabic normalize Pairwise Variability Index (nPVI-Syl), the standard deviation of Variation Coefficient in consonant intervals (VarcoC) and the Syllable rate (rateSyl) were respectively the robust measures in identifying between-sentence variabilities in Qashqai speech rhythm.
