17. Apparatus for producing subunit speech patterns according to claim 16 wherein the means for producing an utterance time frame signal corresponding to the reference word subunit endframe comprises means responsive to said second signal for determining the time of occurrence of the reference word subunit endframe, and means responsive to the best matching time frame path signals for selecting the utterance time frame corresponding to the best time alignment at said time of occurrence.
16. Apparatus for producing subunit speech patterns according to claim 15 wherein said utterance time frame detecting means comprises means for comparing said first signal to the sequence of reference speech pattern time frames to generate a subunit begin frame signal, means for comparing said second signal to the sequence of reference speech pattern time frames to generate a subunit endframe signal, means responsive to said reference subunit begin frame signal and said best matching time frame path signals for producing a signal representative of the utterance time frame corresponding to the reference subunit begin frame, and means responsive to said reference word subunit endframe signal and said best matching time frame path signals for producing a signal representative of the utterance frame corresponding to the reference subunit endframe.
