Application ID: 05877394

Base Claim:
1. A voiced instruction identification system comprising a means for detecting sound which is generated in a form divided into moras, through a microphone with provisions for mounting on a human body; a means for sampling a fundamental wave from the detected sound; a means for determining a value of at least one feature of the fundamental wave for each mora; a means for forming a pattern in respect to relative changes of the value of said feature between contiguous moras; and a means for identifying an instruction from the formed pattern.

Claim 3:
3. A voiced instruction identification system as defined by claim 1, wherein said value determining means includes a means for determining a representative value of frequencies from the fundamental wave of each mora and a means for determining a representative value in respect to at least one of the amplitudes of the fundamental wave of each mora and the duration of each mora.
