PROBLEM TO BE SOLVED: To provide an adaptive acoustic model generating device and program, generating an acoustic model being adapted to a voice in a second task different from a first task by using an acoustic model generated after learning by a voice in the first task. SOLUTION: This adaptive acoustic model generating device (1) is equipped with: a voice recognizing means (21) for performing voice recognizing processing with respect to the voice in the second task and generating a hypothetical word lattice as a result of recognition by using the acoustic model in the first task and a language model for recognizing voice with respect to the voice in the second task, phoneme generating means exclusively for vocalization deforming word (22, 23) for specifying a part of vocalization deformation in the voice in the second task and generating phoneme exclusively for the word for vocalization deformation by using start of writing for the voices in the hypothetical word lattice and the second task; and task adaptive acoustic model generating means (24, 25, 26) for adding the phoneme exclusively for the word for vocalization deformation to the acoustic model in the first task, learning them, and generating the task adaptive acoustic model.
