A method for alleviating a coarticulation problem at word boundaries in connected-word recognition is proposed. This method utilizes the following: (a) Phone-dependent boundary segmentation for word template creation (b) Combination of word templates and VCV (Vowel Consonant Vowel) templates The reference pattern (A) in the drawing shows the phone-dependent boundary segmentation of word templates, in this case "TANI" and "O". If the first phoneme of a word is a plosive such as /p,t,k/, a pause is added at the beginning; if the first phoneme is a vowel such as /a,e,i, o,u/, the beginning of a word is cut deeply. The reference pattern (B) in the drawing shows how a VCV template ("IO" in this case) is applied at the boundary of two words, "TAMI" and "O".
