Opis

As speech recognition of broadcast news is becomingmore mature, research is moving into types of speechthat are more challenging. One such area isconversational speech. Initially telephoneconversations were studied but more recentlyattention moved to meeting recordings. Meetings aresocial events, were people exchange information. This book has presented a study on an automaticminute tacking (AMT) system. By the use of particularcharacteristic provided by SVM classification, thisbook successfully proposes the SVM trainingmisclassification rate (STMR) algorithm for theapplication of speaker change detection (SCD).Experimental results demonstrate that the STMRperformance of outperforms that of conventionalmethods. Also, this book proposes two partialmatching algorithms and a keyword matching algorithmthat can be used to retrieve spoken sentences both ontraining free and language independent.
