Abstract
The aim of this study was to explore the acoustic properties of two emphatic vowels of Algerian dialect produced in oral and nasal context. Recordings were made of four Algerian subjects producing the long vowels /æ:, u:/ in emphatic and non-emphatic /CVC/ syllables both in oral and nasal context. The acoustic analysis was based on an investigation of vowel duration and the first two formant frequencies. Using Praat, vowel duration was automatically measured from the onset of the vowel to the offset. F1 and F2 were extracted at the target vowel midpoint using LPC analysis with the Burg algorithm. The results have shown that emphasis increase vowel duration both in oral and nasal context. However, increase of vowel duration is significant for vowels in nasal context. F1 is raised and F2 is lowered for emphatic vowels both in oral and nasal context. The lowering of F2 was significant for vowels in nasal context. Keywords- Algerian dialect, Emphatic, Oral, Nasal, Vowel duration, Formant frequencies F1, F2.
