1 Introduction. Voice activity detection (VAD) refers to the problem of identifying the speech and non-speech segments in an audio signal. It is a front-end component of many speech processing systems, including robust speech recognition [1, 2, 3] and compression systems for low-bandwidth trans- Cited by: Voice Activity Detection (VAD) is a very important front end processing in all Speech and Audio processing applications. The performance of most if not all speech/audio processing methods is crucially dependent on the performance of Voice Activity Detection. Voice Activity Detection. 1. An important drawback affecting most of the speech processing systems is the environmental noise and its harmful effect on the system performance. Examples of such systems are the new wireless communications voice services or digital hearing aid devices. Thus, We discuss some techniques for Voice Activity Detection identifying and rejecting transmission of silence periods helps (VAD) for Voice over Internet Protocol (VoIP). VAD aids in reduce Internet traffic. multiplexing of sessions so that Internet bandwidth may be used efficiently. Abstract:Voice Activity Detection (VAD), locating speech segments within an au-dio recording, is a main part of most speech technology applications. Non-speech segments, e.g., silence, noise, and music, usually do not carry any interesting infor-mation in speech recognition applications and they even degrade the performance. ABSTRACT We present a novel recurrent neural network (RNN) model for voice activity detection. Our multi-layer RNN model, in which nodes compute quadratic polynomials, outperforms a much larger baseline system composed of Gaussian mixture models (GMMs) and a hand-tuned state machine (SM) for temporal smoothing. Voice activity detection. Voice activity detection (VAD), also known as speech activity detection or speech detection, is a technique used in speech processing in which the presence or absence of human speech is detected. The main uses of VAD are in speech coding and speech recognition.
