摘要：
We use an algorithm based on the adapted-window Malvar transform to decompose digitized speech signals into a local time-frequency representation. We present some applications and experimental results for a signal compression and automatic voiced-unvoiced segmentation. This decomposition provides a method of parameter simplification which appears to be useful for detecting fundamental frequencies, and characterizing formants.
