Abstract
Disclosed is a method for generating word templates for a speech recognition system. It is used where speech is represented by data in frames of equal time intervals. The method includes generating an interim template, generating a time alignment path between the interim template and a token, mapping frames from the interim template and the token along the time alignment path onto an averaged time axis, and combining data associated with the mapped frames to produce composite frames representative of the final word template. The method realizes advantages of reduced memory usage and a realistic data average from each contributing averaged word.
