The problem of detecting pauses is considered, as one of the urgent problems of radio monitoring and detecting speech activity is still to increase the probability for correct detection of relatively short pauses lasting less than 40 ms, which will increase the probability of correct detection of pauses thus increasing the efficiency of using channel resource. The aim of the work is to increase the probability of correct detection and allocation of pauses based on segmentation using auxiliary signals. The information is provided on the developed methods for detecting pauses and their modifications, as well as the results of studying their operation under various parameters, as well as the comparison of their operation with some existing methods for detecting pauses. Pauses are detected in speech signals when vehicle noise with different levels of SNR is superimposed on them.
Key words: : pause detection, voice activity detector.
