摘要: In this paper, we present a novel hybrid keyword spotting system that combines supervised and semi-supervised competitive learning algorithms. The rst stage is S-SOM (Semi-supervised SelfOrganizing Map) module which speci cally designed for discrimination between keywords (KWs) non-keywords (NKWs). second an FDVQ (Fuzzy Dynamic Vector Quantization) consists of discriminating KWs detected by the processing. experiment on Switchboard database has show improvement about 6% accuracy comparing to our best keyword-spotter one.
