DEVICE FOR TRAINING CONVERSATION BASED ON SYNTHESIS

摘要

PURPOSE: To make feedback information available without receiving guidance by a teacher even for any utterance by displaying and observing the correct operation and the articulatory model operation of various kinds of the vocal organs accompanying the vocalization with a type-inputted pronounciation. ;CONSTITUTION: The same two sets in a sound parameter are formed, and when a period of a sign showing the end of the utterance is received, a first set is stored in an array. Then, the sound parameter of a second set is sent to a formant synthesizer to be converted into an output signal forming an analog audio signal 4. The converted output signal is reproduced by a speaker with a loud sound volume 5. Further, the contact between a tongue and the parate of a learner, breathed out air quantity and a sound, etc., are measured, and they are inputted to a conversation traning device 8. Then, the measurement result according to the vocalization of the learner is compared with the stored sound parameter, and the similarity between them is detected and evaluated 9. Thereafter, the feedback is performed to the learner based on a difference between the operation of the vocal organs performed really by the learner and the articulatory model operation 10.;COPYRIGHT: (C)1995,JPO
