Opis:
A woman who drinks alcohol while being pregnant puts her child at risk of numerous birth defects that can negatively affect a child’s cognition, physical growth and behaviour. It is called Fetal Alcohol Syndrome – FAS. Among all these dysfunctions, hearing problems might occur, including the disorders of phonematic hearing and phonematic analysis which result in improper executive functioning. The deficits in executive functioning can lead to real-life implications. According to studies, the children’s ability to operate phonemes should develop with age. Approximately sixty per cent of six-year-old children and almost all ten-year-old children successfully perform phoneme analysis. Undoubtedly, this ability is strongly connected with reading and writing, that is, the basic skills for school children. However, studies on FAS children show that only twenty per cent of sixyear- olds and fifty per cent of ten-year-olds can manage the task of phoneme operations. It is a natural consequence of the problems with memorising sounds and the linear order of words. This failure in developing the skill of phoneme analysis in children leads to dysfunctions in reading and writing.

Opis:
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.
