This paper focuses on audio event detection in tennis match. A new audio event detection method is proposed my making use of contextual information. This method detects the sounds of ball hit and line judge’s shout by the grunts of players when they hit the ball. To model for audio events, the proposed method adopts unsupervised learning to use the information of grunts. Compared with current methods, the proposed method possesses two advantages. First, it does not need any labeled data which is appeal in real applications. Second, this method can reduce the mismatch between training and testing to further improve the performance. Experimental results show that the proposed method can improve the performance of audio event detection substantially.
