Title:
DISCOURSE FUNCTION ESTIMATION DEVICE AND COMPUTER PROGRAM FOR THE SAME
Document Type and Number:
Japanese Patent JP2018031851
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a discourse function detection device for determining a discourse function with high accuracy.SOLUTION: A discourse function estimation device 44 includes: a morpheme analysis part 72 and a time series part-of-speech information storage part 74 for receiving text data of speech production 42, performing morpheme analysis and generating a first feature vector; an F0 extraction part 76, an F0 average storage part 78 and a speaker normalization part 80 for extracting F0 from the inside of a voice signal of 150 milliseconds just before a phase end of a voice signal corresponding to the speech production, and generating a second vector representing a change of F0 by normalizing F0; and a classifier 82 composed of learned SVM or DNN by previous machine learning to receive a feature vector composed of a first vector and the second vector as an input such that a discourse function of the speech production at a phase end is classified into any of a plurality of predetermined discourse functions.SELECTED DRAWING: Figure 2
