PROBLEM TO BE SOLVED: To provide a system and a method for substantially speaker-independent recognition that decrease or eliminate problems relating to conventional systems. SOLUTION: The system and method of determining an out-of-vocabulary score for speaker-independent recognition of user-defined phrases comprises enrolling a user-defined phrase with a set of speaker-independent (SI) recognition models (34) using an enrollment grammar (36). An enrollment grammar score of the spoken phrase may be determined by comparing features of the spoken phrase to the SI recognition models (34) using the enrollment grammar (36). The enrollment grammar score may be penalized to generate an out-of-vocabulary score (94). COPYRIGHT: (C)2007,JPO&INPIT
