PURPOSE: To provide a speech recognizing method for efficiently executing modeling expressing the attendance of articulation between words. CONSTITUTION: This speech recognizing method for modeling the context of adjacent words, includes a step for dividing one word or a silent period into two parts, a step for dividing a second word adjacent to the first word or the silent period into two parts, and a step for making an acoustic model by connecting a tail part 58 of the first word or the silent period with a head part 60 of the second word or the silent period. Also, the method includes a step for preparing a grammar for limiting the acoustic model to a middle-to- middle context.
