Abstract :
The concept and algorithm of the speech wave abnormal index (SWAI) is presented to describe the damaged degree of speech signals, which are disturbed by noise or/and crosstalk speech. By using the method of parallel processing to estimate the pitch periods of speech in the time domain, an algorithm for calculating the SWAI is put forward. Theoretical analysis and experimental results show that the SWAI not only can be applied to detect crosstalk speech, but also is an important feature parameter of speech signals in objective speech quality assessment.
