Abstract
A technique for improving speech recognition in low-cost, speech interactive devices. This technique calls for selectively implementing a speaker-specific word enrollment and detection unit in parallel with a word detection unit to permit comprehension of spoken commands or messages when no recognizable words are found. Preferably, specific speaker detection will be based on the speaker's own personal list of words or expression. Other facets include complementing non-specific pre-registered word characteristic information with individual, speaker-specific verbal characteristics to improve recognition in cases where the speaker has unusual speech mannerisms or accent and response alteration in which speaker-specification registration functions are leveraged to provide access and permit changes to a predefined responses table according to user needs and tastes. Also disclosed is the externalization and modularization of non-specific speaker recognition, action and response information to enhance adaptability of the speech recognizer without sacrificing product cost competitiveness or overall device responsiveness.
