- Abstract:
- This study is a research on Persian Intonational System, which was carried out within the Autosegmental-Metrical framework.The intonational elements of Persian are represented by two distinctive levels (High and Low). Persian intonation system enjoys three main elements: pitch accents, Phrase accents and boundary tones. Every intonational element has its own meaning. The data of study is about 200 utterances produced by two Persian native speaker one male and one female. These utterances have been annotated in four levels in PToBI: phoneme level, word level, tone level and break index level. In this study we aimed to formulate the acoustic representation of the intonational elements by three main acoustic elements: fundamental frequency, duration and intensity. We tried to find out the categorical meaning of them in different places of the speech. We used PRAAT and the annotated data to measure the value of three main acoustic features. Finally we made a perceptual test based on these findings and asked 5 Persian native speakers to listen to them and confirm or reject our results. The results showed that Persian intonation elements have categorical status and 3 main intonational elements were formulated
