End Points Detection Widget

The problem of speech modeling is handled here using a new technique. The features are extracted from wavelet packets decomposition of speech signal. Wavelet packet bands are chosen to match the natural hearing response. Widgets are fixed probabilistic patterns that may be utilized to monitor specific physical phenomena. Many widgets may be designed to express some phenomena like speech end points, voiced/unvoiced and phone boundaries. In this paper the point chosen is end points widget. Signal with almost S/N = 0 (db) are still discriminate using EPD widget.
