Claim One:
1. An information processing method in which by an information processing system comprising a storing unit storing question information, an output unit outputting the question information and an accepting unit accepting a voice, the question information stored in the storing unit is outputted, an answer to the outputted question information is accepted by voice, acoustic features associated with the accepted voice are extracted, and information accompanying the voice is presumed based on the extracted acoustic features, said information processing method comprising the steps of outputting, from said output unit, a first piece of question information and a second piece of question information previously stored in said 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.
