1. A speech recognition system comprising:

  • a hypothesis search unit which searches for an optimal solution of inputted speech data by generating a hypothesis which is a bundle of words which are searched for as recognition result candidates;

    a self-repair decision unit which calculates a self-repair likelihood of a word or a word sequence included in the hypothesis which is being searched for by the hypothesis search unit, and decides whether or not self-repair of the word or the word sequence is performed; and

    a transparent word hypothesis generation unit which, when the self-repair decision unit decides that the self-repair is performed, generates a transparent word hypothesis which is a hypothesis which regards as a transparent word a word or a word sequence included in a disfluency interval or a repair interval of a self-repair interval including the word or the word sequence,wherein the hypothesis search unit searches for an optimal solution by including as search target hypotheses the transparent word hypothesis generated by the transparent word hypothesis generation unit.
