Abstract

This article considers the algorithm “Voice activity detection” and the using VAD algorithm in the system of Kazakh speech recognition. The paper presents a mathematical model VAD and methods for detecting voice data: pauses between sentences, words, individual sounds. VAD algorithm is adapted to the recognition of Kazakh speech counting the basic properties of Kazakh language. Voice activity detection researches in Kazakh speech are being conducted for the first time. The results of the spectral analysis are displayed on the picture.
