| Abstract(in English) | Introduction of hands-free interface into speech recognition (SR) systems is expected for natural iteraction between humans and spoken dialogue robots. In hands-free SR system, Signal-to-Noise Ratio (SNR) of input signal becomes worse because of background noise in real-environment and other reasons. This will cause degradation in recognition performance when using conventional Voice Activity Detection (VAD). In this paper, we evaluate hands-free SR algorithm using decoding VAD based on acoustic and language models for robust VAD in noisy environment. We performed experiment for comparing proposed and conventional VAD method, for example, based on amplitude power, statistical model and GMM. And, we evaluate effectiveness of the proposed method. |
