The Gemination Effect on Consonant and Vowel Duration in Standard Arabic Speech

In this paper, we expose the results of an experimental study of acoustic properties of geminated consonants in Arabic language. We aim to determinate the temporal relationship between doubled consonant and the length of the vowel preceding them in a VCCV sequence. We compare these values with those measured for a VCV sequence. The results proved that the duration of simple consonant was sensibly different from the geminated one and same for the duration of the vowel preceding it. This work was undertaken to determinate the consonant duration characteristics to distinguish between a simple consonant and the geminated one in standard Arabic speech recognition.
