Abstract


The current research compares the acoustic correlates of pitch accent of two urban dialects of spoken Serbian, urban Niš and Novi Sad. We analyzed spontaneous speech of nineteen native speakers of Serbian with regard to vowel duration and fundamental frequency ratios. It was shown that the tone between the stressed and post-stressed vowel is generally falling in the speech of Niš, while in the speech of Novi Sad it reflects the tone of the expected pitch accent in that particular word. The same is true of the interval between the end of the stressed and the beginning of the post-stressed vowel, which is always rising in the speech of Niš. In Niš, speakers tend to produce vowels in words with falling accents as longer than in words with rising accents. On average, vowels are longer in the speech of Novi Sad. Bearing in mind that regional variations provide important forensic markers (Kašić and Đorđević 2009), this research aims to contribute to the discipline of forensic phonetics, in particular to speaker profiling. Its significance also lies in the fact that it examines spontaneous speech, and is thus relevant for forensic casework (Rose 2002; Nolan, de Jong, and McDougall 2006).
