1. A speech recognition system comprising: an identifier for adding an identifying code to utterance data corresponding to signals generated by utterances of each of a plurality of users, the identifying code being available for identifying each of the users, a calculator for rating the utterance data by a value for each of the identifying code, the value being determined on the basis of comparison of characteristics of the utterance data with characteristics of word information selected from a plurality of sets of word information stored; storage for storing N pieces of vocabulary information corresponding to N sets of the utterance data, the utterance data having a same identifying code, the N sets of utterance data having the value within top N, N being an integer equal to one or more; a selector for selecting posterior N pieces of word information posterior in time to prior N pieces of word information, the identifying codes of the utterance data relative to the posterior and prior N pieces of word information being spoken by the users that are different from each other; a relational calculator for calculating a degree of relationship between the prior and posterior N pieces of word information, the degree of relationship being capable of rating a fact of the utterance relative to the posterior N pieces of word information being performed later than the utterance relative to the prior N pieces of word information; a first determiner for determining the posterior N pieces of word information corresponding to an utterance performed later than the utterance relative to the prior N pieces of word information; and a second determiner for determining the posterior N pieces of word relative to an utterance as a response to the utterance relating to the prior N pieces of word information on the basis of a predetermined condition.
