Description: 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 signal is acquired in noisy environments. The
proposed VAD method uses an additional stage of wavelet
subband denoising. We compared this approach with other
standard methods i.e.: zero-crossing rate and spectral
entropy analysis. Additionally we present in this paper our
basic results illustrating the main aim of this contribution,
consisting in application of intelligent denoising strategies
to various VAD algorithms.

Description: Huffman coding is an entropy encoding algorithm used for lossless data compression. The term refers to the use of a variable-length code table for encoding a source symbol (such as a character in a file) where the variable-length code table has been derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol. It was developed by David A. Huffman while he was a Ph.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".
