ABSTRACT

This paper describes a keyword spotting based audio searching engine that can through a lpng recordings of radio broadcast with a low missing rate. Bothth sub-sylllable (Initial- Final) and base-syllable based keyword spotting strategies are investigated. The system can achieves a 20% misssing rate with around 1.5 false alarm per hour (FA/KW/H) and the performance cam be further improved to zero missing rate with as low as 0.5 FA/KW/H by incorporating better keyword specifications.
