Abstract: A mandarin speech input method for directly translating arbitrary sentences of mandarin speech into corresponding Chinese Characters. The present invention is capable of processing a sequence of "mono-syllables," "(but each of the characters in the poly-character word is continuous)," "prosodic segments," or even a "whole sentence of continuous mandarin speech." A prosodic segment comprising one or more words is a segment that is automatically isolated by a speaker by pausing where characters in the prosodic segment are continuous.
