摘要：
The task of keyword spotting is to detect a set of keywords in the input continuous speech. The main goal of this work is to develop an improved mandarin keyword spotting (KWS) system for conversational telephone speech (CTS). In this paper, we propose an efficient online-garbage model based KWS system, which integrated with a word-level minimum classification error (MCE) training method and a novel context-enhanced verification method. Experiment showed that the proposed methods can reduce the Equal-Error-Rate (EER) of the system by 13.8% in relative.
