PROBLEM TO BE SOLVED: To provide a sound model generating device, a speech recognizing device, and a sound model generating program that can effectively use accumulated speeches without excessive learning. SOLUTION: The sound model generating device 1 generates a sound model having a phoneme environment sharing structure common to a reference sound model as to a learning speech different from a reference speech as a speech to be referred to by using a reference sound model using a probability density distribution of feature quantities observed with respective phonemes included in the reference speech, and includes a reference sound model acquiring means 3, a learning speech acquiring means 5, a learning speech statistics parameter calculating means 7, a learning speech statistics parameter substituting means 9, and a model generating means 11.
