In this paper, we attempt to use pitch contour in Mandarin isolated words recognition by matching candidate pitch contour with a set of templates. To apply it in speaker-independent speech recognition, we propose a remedy algorithm to weaken speaker information in pitch contour. Speaker-dependent and - independent speech recognition experiments are carried(More)
