This study aims to analyze the correlation between ictus and acoustic features of duration, intensity and pitch in Persian folk poems. For this purpose, 51 lines of Persian folk poems were recorded, which consisted of 139 syllables in ictus positions and 139 syllables in off-ictus positions. Each line was segmented into syllables, feet and colons. The vowels in ictus and off-ictus positions were analyzed acoustically and the amounts of pitch, intensity and duration of vowels were measured manually. In order to compare the acoustic features of these vowels, Some Paired two-sample t-test were conducted. The results suggested that: a) duration of vowels in ictus positions is more than that of vowels in off-ictus positions. In addition, analytic statistics showed that the effect of ictus on the duration of vowels is significant; b) the mean intensity of vowels in ictus positions is less than that of vowels in off-ictus positions. Furthermore, analytic statistics indicated that the effect of ictus on the intensity of vowels is significant and c) the vowels in off-ictus positions have lower pitch values than those in ictus positions. Moreover, it was declared that the effect of ictus on the pitch value of vowels is not significant.

Research showed that in some languages, speakers accent new referents and deaccent given referents. The research also indicated that the pitch accent type used to mark accessible referents is like that used to accent given referents. The goal of the present study was to investigate the different pitch accent patterns used to mark different information status (new, given, accessible and identifiable) in the narrative discourse of the monolingual Persian- speaking adults. Moreover, since no research has been done on the intonational patterns of accessible and identifiable referents in Persian, pitch accent and intonational pattern of these referents were also investigated. To these aims, 10 monolingual Persian-speaking adults were encouraged to narrate stories based on 8 picture stories in which information status of referents were carefully controlled. The stories were labeled to determine whether they included target words, full NP, pronouns. The subjects’ pitch accent patterns were identified using Praat software. Findings of the study revealed that the most frequent accent types used to mark new, given and accessible referents were  L+(H*) H+(L*) and H*+L respectively. It was also found out that there was no specific accent type to mark identifiable referents in Persian. Based on the results, it could be suggested that there was a specific relationship between information status and pitch accent types in the subjects’ narrative discourse.
