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.
