A method of voice recognition with a boundary binding type in consideration of a kind of a voice boundary estimates a probability where a boundary corresponds to every kind basis of the voice boundary. For a group of parameters within a window of a predetermined time width, the method is to calculate a group of common probability densities independent from the kind of the voice boundary, to multiply the result by first polynomial coefficient and to calculate a first probability where the voice boundary exists in a center of a window, to further multiply the result by a second polynomial coefficient and to calculate a second probability where the voice boundary does not exist in center of a window. A boundary likelihood dependent on a kind of voice boundary is obtained from the first and second probability densities. The voice recognition device compares with a threshold value depending on the kind of phonemic boundary when the time for producing the boundary of the phonemic model series is limited within a region of the phonemic boundary or the neighborhood of the phonemic boundary which is estimated in accordance with a boundary estimating method for the voice corresponding to the kind of phonemic boundary.
