Key Word Recognition.
Abstract
This report describes the design, development and feasibility evaluation of a key word recognition system designed to detect key words/phrases embedded in narrow bandwidth conversational speech. It has been a goal that the techniques developed during this program be independent of the speaker. A real-time, dual processing level, key word recognition technique has been developed during this program. The technique utilizes the occurrence of a sequence of phonemic events to identify a candidate key word. A fine grained analysis is then performed on the speech segment containing the candidate word to determine if it is the key word of interest. A series of narrow band data recordings have been generated during the course of this investigation. An improved sequential logic element has been developed and the features and programmable sequential logic system of the RADC Voice Information Processor (VIP) has been interfaced to a minicomputer.
