Pronunciation behavior visualization device and pronunciation learning device

摘要

The purpose of the present invention is to provide a device capable of visualizing pronunciation movements from the speech of a learner in order to facilitate correction of pronunciation errors by the learner, and to provide a learning device that uses the visualization device. The present invention includes a speech acquisition means (21) for acquiring input speech, a vocal tract parameter conversion means (26) for converting speech data acquired by the speech acquisition means into a vocal tract parameter series, a coordinate vector series conversion means (29) for converting the vocal tract parameter series into a coordinate vector series indicating the outline of an articulatory organ, an image generating means for generating an image of the movement of the articulatory organ from the coordinate vector series, and an image display means for displaying the image generated by the image generating means.
