Sixth European Conference on Speech Communication and Technology

This paper represents a way for the detection of startend boundaries of a speech segment in the presence of noise using wavelet transform. The technique is based on generating a certain mathematical function derived from the wavelet parameters that can keep track with the energy changes along the speech duration. The problem in end points detection always appears in words that begin or end in lowenergy phonemes. This problem can be entirely eliminated by this technique. Examples are given to show how the algorithm performs under different signaltonoise ratios.
