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