Abstract

A system and method for processing human language input uses collocation information for the language that is not limited to N-gram information for N no greater than a predetermined value. The input is preferably speech input. The system and method preferably recognize at least a portion of the input based on the collocation information.

Claims

1. In an information processing system, a method for speech recognition, the method comprising the steps of:

accepting a speech utterance;

accessing maintained collocation information regarding language units, wherein the collocation information is indicative of collocation and is not merely N-gram information for N no more than a predetermined value; and

recognizing at least a portion of the speech utterance based on the collocation information.

2. A system for automated speech recognition, the system comprising:

means for accepting a speech utterance;

means for accessing maintained collocation information regarding language units, wherein the collocation information is indicative of collocation and is not merely N-gram information for N no more than a predetermined value; and

means for recognizing at least a portion of the speech utterance based on the collocation information.
