This study investigates the intonational properties of vocative structure in standard Persian in the framework of Auto-segmental-metrical phonology. Pitch accent is one of the elements whithin this framework, that refers to the prominence in the utterance. In Persian all lexical units are stressed in their final syllable and there is a language-specific feature in Persian according to which pitch accents are aligned with lexically stressed syllables. Contrary to the said feature, previous studies claim that in vocative structure, it is the first syllable that is accented, due to the difference existed between intonation pattern of vocative structure compared to its citation form. The data... 

Theoretically, it has been proved that pitch changes has an specific phonological system in Persian and the main intonational elements (i.e. pitch accent, phrase tone and boundary tones) have a known independent identity and can change independently. These changes give different intonational forms to utterances. In addition, it has been demonstrated that sound pattern of Persian syntax units follow HAP (Head Avoidance Principle) and Always, the farthest argument from the head takes the pitch accent. In the present thesis, phonetic values of intonational elements in 5 emotions of PESD database utterances (i.e. Anger, Disgust, Sadness, Happiness and Fear) are quantified and then, they are...
