Application ID: 06322748

Base Claim:
1. A method for producing subunit speech patterns comprising the steps of: storing a plurality of reference speech pattern templates each comprising a time frame sequence of acoustic feature signals representative of a prescribed spoken reference speech pattern; storing a set of signals each representative of the time of occurrence of at least one predetermined subunit in the reference acoustic feature signal sequence for each reference speech pattern; analyzing an utterance of one of said stored reference speech patterns to generate a time frame sequence of acoustic feature signals representative of the utterance; generating signals representative of the time alignment of said utterance feature signal sequence and said stored reference speech pattern feature signal sequence; and determining the sequence of utterance feature signals corresponding to the predetermined subunit in said stored reference speech pattern template responsive to the time alignment signals and said reference subunit time of occurrence representative signals.

Claim 2:
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.
