Abstract : In this paper the effect of using the coefficients of the low frequency filters at different levels of the wavelet transform of an Arabic speech samples is presented. Specifically, the discrete wavelet transform is computed to approximate a speech signal at different wavelet levels in preparation for speech processing, or transmission. The low frequency wavelet coefficients at each level of the decomposition are used as a representation for the Arabic speech signal in the wavelet domain. Then, the auto-correlation of the resulted low-frequency coefficients is computed to find out the effect of the wavelet level on the peak of the correlation of the processed Arabic speech signal. Using this method, cross-correlating the entire unknown speech sequence with a known speech sample, in order to recognize the spoken speech, is avoided. Also, the time taken for recognizing or transmitting a speech sample can be decreased due to the reduction in the sequence length that represents the speech sample. The results showed that Arabic speech samples are identified satisfactorily to 1/6.25 resolution. The quality of the Arabic speech samples is affected by the level of the wavelet transformation. The experiments showed that the wavelet transform can be carried out to the third level of the wavelet decomposition with an acceptable audition quality.
