Originální abstrakt

This paper deals with the method of voice activity detection. The paper aims especially to two detector types; these are the detector based on short-time signal energy and statistical model-based voice activity detector. Decision-making rules of the statistical model-based detector are derived from the LRT %(Likelihood Ratio Test) by estimating unknown parameters using the ML %(Maximum Likelihood) criterion. In addition there is an effective hang-over scheme based on HMM %(Hidden Markov Model) principles in the detector. The results were evaluated and compared for various types of noises and SNR values.
