ABSTRACT:
Described herein, is an arrangement and method for processing speech information in a speech recognition system (300). In such a system where the speech information is depicted as words, each word representing a sequence of frames (510) and where the recognition system has means (120) for comparing present input speech to a word template, the word template stored in template memory and derived from one or more previous input word, the present invention is best employed. The invention describes combining contiguous acoustically similar frames (512) derived from the previous input word or words into representative frames to form a corresponding reduced word template, storing the reduced word template in template memory in an efficient manner, and comparing frames of the present input speech to the representative frames of the reduced word template according to the number of frames combined in the representative frames of the reduced word template. In doing so, a measure of similarity between the present input speech and the word template is generated.
