This study is an extension of our last researches about the detection of transition zones
based on multiresolution spectral analysis (MRS). In this paper we present the fourth step
for the realization of an automatic system for Tunisian Dialect segmentation and analysis.
The MRS is calculated over several Fast Fourier Transforms (FFT) of different length. It
can provide a higher temporal accuracy in the upper spectral region and a better frequency
resolution in the lower spectral range. We showcase the importance of this tool by attempt-
ing to an automatic transition zones detection by calculating the Interquartile Range (IQR)
of all frames of the MRS FFT. We applied our Visual Assistance of Speech Processing
(VASP) System to a corpus. This corpus was in Tunisian Dialect pronounced by tunisian
speakers. The analysis of the obtained results shows that the automatic detection of tran-
sition zones based on MRS provides better results compared to classical spectral analysis of
the corpora used.
