Wavelets and JPEG2000: A brief review Beyond wavelets and JPEG2000 My exploration Directional wavelet construction Adaptive wavelet selection Inter-subband transform Outlook

In this paper we propose a method for voice activity detection (VAD) in a speech signal recorded in the presence of noise. The so-called endpoint detection (EPD), i.e., detection of voice activity (speech) boundaries is very difficult if the
