Abstract
Abstract A method and apparatus are provided for identifying one or more boundaries of a speech pattern within an input utterance. One or more anchor patterns are defined, and an input utterance is received. An anchor section of the input utterance is identified as corresponding to at least one of the anchor patterns. A boundary of the speech pattern is defined based upon the anchor section. Also provided are a method and apparatus for identifying a speech pattern within an input utterance. One or more segment patterns are defined, and an input utterance is received. Portions of the input utterance which correspond to the segment patterns are identified. One or more of the segments of the input utterance are defined responsive to the identified portions.
