System and method for health care information processing based on acoustic features
First Claim
1. An information processing method comprising the steps of:
- outputting, from an output unit, a first piece of question information and a second piece of question information previously stored in a storing unit and correlated with each other;
accepting answers to the outputted first and second pieces of question information by voice;
extracting character string information from a voice associated with the accepted answer to the first piece of question information;
extracting at least one piece of feature information associated with the acoustic features from a voice associated with the accepted answer to the second piece of question information;
storing the extracted character string information and feature information so as to be associated with each other;
setting a correlation between the stored character string information and feature information; and
identifying, when a voice associated with an answer to the second piece of question information is newly accepted by said accepting unit, character string information correlated with at least one piece of feature information associated with the acoustic features extracted from the accepted voice, based on the piece of feature information and the set correlation.

Abstract
A question as to the physical condition and a question as to the feeling are asked, answers are accepted by voice, acoustic features are extracted from the answer to the question as to the physical condition, and character string information is extracted from the answer to the question as to the feeling. A correlation between the acoustic features and the character string information is set, and character string information is identified from a newly accepted acoustic feature, thereby performing feeling presumption. Feeling is presumed from the voice in response to the subject'"'"'s severalty and changes in the subject'"'"'s age and physical condition. A medical examination by interview on the mental condition is performed on the subject by voice output and voice input, and the subject'"'"'s mental condition is diagnosed based on the contents of the subject'"'"'s answer and analysis of the answer by voice.
