27. A device for determining voice recognition accuracy of a voice recognition system that recognizes a voice command in a user utterance, comprising: an analysis module that analyzes voice recognition information produced by the voice recognition system and compares a manually transcribed version of the user utterance to the recognized voice command; an error detection module that detects at least one recognition error based on the analysis, comprising detecting at least one of: an in-grammar false accept (IGFA) type error, an in-grammar false reject (IGFR) type error, an out-of-grammar false accept (OGFA) type error, or an out-of-grammar correct reject (OGCR) type error; an error source identification module that identifies at least one source of error for the detected recognition error; and a solution generation module that generates at least one solution to eliminate the source of error.
