Immediate Recognition of Embedded Command Words

Abstract

In this paper we describe a. method for recognizing command words in a real-time speaker dependent isolated word speech recognition system such as the one developed at IBM. In such a system a few words are designated as commands and these may occur interspersed with other words in dictation. Given a set of command word; and a. few training tokens of each of the command words we construct special models for each of the command words and use a key-word spotting algorithm to identify occurrences of any of the command words very accurately. We are able to achieve near 98% detection rate with negligible false alarm rates.
