“…1 give F1 and F2 give indication about the constrictions of the vocal tract in generating vowels [23]. Based on the study [24], a formant-based analysis for the six vowels of MSA language was carried out and the values of the first three-formant frequencies were captured. Their results were compared to some previously published ones conducted on MSA and other Arabic dialects.…”

In this paper, a new method for segmenting speech at the phoneme level is presented. For this purpose, author uses the short-time Fourier transform of the speech signal. The goal is to identify the locations of main energy changes in frequency over time, which can be described as phoneme boundaries. A frequency range analysis and search for energy changes in individual area is applied to obtain further precision to identify speech segments that carry out vowel and consonant segment confined in small number of narrow spectral areas. This method merely utilizes the power spectrum of the signal for segmentation. There is no need for any adaptation of the parameters or training for different speakers in advance. In addition, no transcript information, neither any prior linguistic knowledge about the phonemes is needed, or voiced/unvoiced decision making is required. Segmentation results with proposed method have been compared with a manual segmentation, and compared with three same kinds of segmentation methods. These results show that 81% of the boundaries are successfully identified. This research aims to improve the acoustic parameters for all the processing systems of the Arab speech.

“…Therefore, when these vowels are plotted F1 to F2, they form two triangles. The results of the analysis of the first three formants are summarized in Table 2 where speakers uttered perfectly Arabic phonemes without any influence by their local dialects [24].…”
