ABSTRACT:
A technique for improving voice recognition in low-cost, speech interactive devices. This technique calls for implementing a affirmative
egative discrimination unit in parallel with a word detection unit to permit comprehension of spoken commands or messages issued by binary questions when no recognizable words are found. Preferably, affirmative
egative discrimination will include either spoken vowel analysis or negative language descriptor detection of the perceived message or command. Other facets include keyword identification within the perceived message or command, confidence match level comparison or correlation table compilation in order to increase recognition accuracy of word-based recognition, volume analysis, and inclusion of ambient environment information in generating responses to perceived messages or queries.
