| Abstract: |
An apparatus for automatically identifying command boundaries in a conversational natural language system, in accordance with the present invention, includes a speech recognizer for converting an input signal to recognized text and a boundary identifier coupled to the speech recognizer for receiving the recognized text and determining if a command is present in the recognized text, the boundary identifier outputting the command if present in the recognized text. A method for identifying command boundaries in a conversational natural language system is also included.

What is claimed is:
1. An apparatus for automatically identifying command boundaries in a conversational natural language system, comprising:
- a speech recognizer for converting an input signal to recognized text; and
- a command boundary identifier coupled to the speech recognizer for receiving the recognized text and determining if a command is present in the recognized text, the boundary identifier outputting the command if present in the recognized text, wherein the boundary identifier includes an input processor to process the recognized text by augmenting each word in the recognized text by the word's relative position with respect to a hypothesized command boundary.
