摘要
PURPOSE: To provide an accented phrase boundary detecting device which can detect accented phrase boundaries for continuous speech recognition at a smaller error rate and to remarkably shorten the processing time for the detection. ;CONSTITUTION: Based on the pose and pitch pattern detected on the basis of voice uttered for learning, the voice is modelled to a model represented by the parameters of accent components and phrase components to detect the accent model patterns 20. After the detected accent model patterns 20 are converted into pitch patterns, they are subjected to clustering to calculate the average of the accent model patterns 20 belonging to each cluster and thereby plural templates for reference to each cluster. The distance between the pitch pattern and the reference template is adjusted to be small based on the pose and pitch pattern detected based on the utterance for detection to detect the accented phrase boundary based on the connecting boundary of each template.;COPYRIGHT: (C)1996,JPO
