12. Apparatus for producing subunit speech patterns according to claim 11 wherein said subunit time of occurrence signal storing means comprises means for storing a first signal representative of the time frame of the reference speech pattern template at which said subunit begins and for storing a second signal representative of the time frame at which said subunit terminates; and said selecting means comprises means responsive to said time alignment signals for 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 means for storing the utterance feature signals of the interval from said first time frame to said second time frame.
