PROBLEM TO BE SOLVED: To provide a speech recognition method capable of performing speech recognition by speaker adaptation without needing a storage medium with large capacity for storing the acoustic model, etc., of a particular speaker and without having to identifying the particular speaker in advance, and to provide a device and a program therefor. SOLUTION: This speech recognition device 1 using an acoustic model in which each phoneme of a speech signal to be an object of speech recognition is composed of a plurality of statistical distributions, a language model in which each inter-word relation is composed of a statistical distribution, and a word pronunciation dictionary for showing the relation between a word and a phoneme, is provided with a statistical distribution specification means 3a for specifying a statistical distribution with high output probability among a plurality of statistical distributions of the acoustic model on the basis of a result obtained by vocally recognizing speech uttered by a speaker desired to be adapted, and a speech recognition means 3b for recognizing the speech to be recognized on the basis of the statistical distribution specified by the statistical distribution specification means.
