Voice Activity Detection in Noisy Environments Based on Double-Combined Fourier Transform and Line Fitting
A new voice activity detector for noisy environments is proposed. In conventional algorithms, the endpoint of speech is found by applying an edge detection filter that finds the abrupt changing point in a feature domain. However, since the frame energy feature is unstable in noisy environments, it is difficult to accurately find the endpoint of speech. Therefore, a novel feature extraction algo...
متن کاملVoice activity detection in noisy environments
The subject of this paper is robust voice activity detection (VAD) in noisy environments, especially in car environments. We present a comparison between several frame based VAD feature extraction algorithms in combination with different classifiers. Experiments are carried out under equal test conditions using clean speech, clean speech with added car noise and speech recorded in car environme...
متن کاملA model based voice activity detector for noisy environments
This paper presents a model-based voice activity detector (VAD) aimed at operating in low signal to noise ratio conditions and non-stationary noise environments. The proposed system makes use of Gaussian mixture models trained on Mel Frequency Cepstral Coefficients extracted from noisy speech data. In addition, information from smoothed frame based log energy is used to augment the system to de...
متن کاملRobust Voice Activity Detection Based on Discrete Wavelet Transform
This paper mainly addresses the problem of determining voice activity in presence of noise, especially in a dynamically varying background noise. The proposed voice activity detection algorithm is based on structure of three-layer wavelet decomposition. Appling auto-correlation function into each subband exploits the fact that intensity of periodicity is more significant in sub-band domain than...
متن کاملEntropy based voice activity detection in very noisy conditions
This paper addresses the problem of robust voice activity detection (VAD) capable for working at very low signal-to-noise ratios (SNR<10dB). A new algorithm that we propose is based on entropy estimation measures of the time-frequency magnitude spectrum. The problem of the estimation of the distribution of noise in detected non-speech segments of analysed signal is also presented. It is shown t...
