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 i...
