Perceptual Confusion Among Some Arabic Consonants (in Arabic)
Auther : Mohamed S. El- Dalee
Speech perception can not be accounted for solely in terms of acoustic analysis . Auditory memory of native speakers stores acoustic cues for a segment . These cues are used in the phonetic stage as a basis for naming or classification of phonemic segments. This research attempts to explore the effect of background noise upon the average magnitude of the problem to manageable size. The research dealt with the following twelve Arabic consonants.
/ b t d k d f o j x y m n z /
A list of 264 nonsense triconsonantal words was prepared, randomized, uttered, recorded and presented to an audience of ten Egyptian university students. The recorded data were run twice: first, without noise, second, with background noise. The listening responses were processed statistically through confusion matrices. The results indicated the degree of intelligibility for the different classes of consonants, and the total percentages were:
Point of Articulation 80%
Voicing 70%
Manner of Articulation 63%
