2. A method for producing subunit speech patterns according to claim 1 wherein said subunit time of occurrence signal storing step comprises storing a first signal representative of the time frame of the reference speech pattern template at which said subunit begins and storing a second signal representative of the time frame at which said subunit terminates; and said determining step comprises detecting a first time frame of the utterance corresponding to said first signal and a second time frame of the utterance corresponding to said second signal, and storing the utterance feature signals from said first time frame and to said second time frame.

A method for producing subunit speech patterns according to claim 2 wherein said time aligning step comprises modifying said utterance feature signals to match the number of time frames in said utterance to the number of time frames in said stored reference speech pattern jointly responsive to the utterance feature signals and the stored reference speech pattern feature signals.
