Spectral analysis of vowels /a/ and / ε/ in Tunisian context
Tunisian dialect is a mixture of several languages; Arabic, Berber, French, Italian, English and Spanish. In this paper, we introduce a study of two common vowels /a/ and/ε/in tunisian dialect and french. Vowels are pronounced in tunisian context. Our study is realized in time-frequency domain. Firstly, we present our corpus and our system Visual Assistance of Speech Processing VASP, which are used to realize our analysis. Then, we describe two visual representations in time-frequency domain: classical and multiresolution spectrogram. Finally, we apply VASP on tunisian dialect and french language. The analysis of the obtained results shows that due to the influence of french language on the tunisian dialect, the vowels /a/ and/ε/ are, in some contexts, similarly pronounced.
