摘要

A speech recognition system comprises a recogniser (2) for receiving speech signals from users. The recogniser (2) compares each received word with templates of words stored in a reference template store (3) and flags each template that corresponds most closely to a received word. The flagged templates are stored in a template store (11). The recogniser (2) compares the speech pattern from a given user of a second utterance of a word for which a flagged template is already stored in the template store (11) with the templates stored in the reference template store (3) and with the flagged templates in the template store (11), so as to produce a second flagged template of that word. The second flagged templates are also stored in the template store (11). Sifting means (21) analyse a group of flagged templates of the same word, and produce therefrom a second, smaller group of templates of that word. These templates are stored in another template store (22)
