Intonation Pattern of Information Structure (IS) in Kashani Dialect

This study aimed to investigate the intonation pattern of Kashani utterances with broad, narrow, and contrastive focuses on different syntactic structures, which were obtained by changing the order of verbs, subjects, and objects. Our data included 4 sentences produced in 3 syntactic structures with a broad focus, 1 syntactic structure with a narrow focus, and 1 syntactic structure with a contrastive focus produced by 16 speakers (8 males and 8 females) from Kashan City. The data were recorded in an anechoic chamber with the sampling frequency of 22050 Hz. A total of 320 utterances (4 sentences × 5 cases × 16 speakers) were annotated in the 2 tiers of tone and phone by using Praat software. The fundamental frequency (F0) of each word was measured at 5 intervals. After the average value of F0 was calculated for each word, their pitch contours were drawn. The results showed that the pitch contours of unmarked Kashani utterances followed a falling pattern. Moreover, the pitch contours were sensitive to the position of each verb as the sentence nucleus. "Verb" was the last constituent that received the pitch accent in a sentence, while it de-accented the constituents coming after it. Finally, the focal constituents appeared at the end of the sentences with narrow or contrastive focuses. These constituents had high prominence and amplitude compared to the other constituents in the sentences. In addition, alignment of the accent peaks in all the accented syllables corresponded to the vowels of the next syllables. The results of this research could be helpful in understanding the typologies of languages and dialects and identifying speakers of varied dialects.
