Title:
EVALUATION DEVICE, TRAINING DEVICE, METHODS THEREFOR, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/235089
Kind Code:
A1
Abstract:
An evaluation device: employs a low-pass filter with a cutoff frequency of a first predetermined value or a second predetermined value greater than the first predetermined value while causing a change or not causing a change to a feedback formant frequency that is a formant frequency of a collected speech signal; converts the collected speech signal and feeds back the converted speech signal to a subject; and calculates a compensation response vector using a collected formant frequency that is the formant frequency of a speech signal obtained by collecting the utterance made by the subject while feeding back to the subject the speech signal converted by changing the feedback formant frequency, and a collected formant frequency that is the formant frequency of a speech signal obtained by collecting the utterance made by the subject while feeding back to the subject the speech signal converted by not changing the feedback formant frequency. The evaluation device includes an evaluation unit that obtains an evaluation on the basis of a compensation response vector for each cutoff frequency.
