A speech recognition device has: hypothesis search means 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; self-repair decision means 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 means, and decides whether or not self-repair of the word or the word sequence is performed; and transparent word hypothesis generation means which, when the self-repair decision means 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 an un-repaired interval related to the word or the word sequence, and the hypothesis search means searches hypotheses for an optimal solution, the hypotheses including as search target hypotheses the transparent word hypothesis generated by the transparent word hypothesis generation means.
