Abstract: Un método para uso en un programa informático para reconocimiento de voz que funciona en diversos estados y ejecuta un programa para poner en práctica diversos sucesos, para reconocer una instrucción oral, que comprende los pasos de: monitorizar (54) al menos uno de dichos sucesos y estados; recibir una instrucción procesada correspondiente a dicha instrucción oral; analizar (44) dicha instrucción procesada de acuerdo con al menos un modelo acústico a fin de identificar una probable coincidencia acústica; analizar (48) dicha instrucción procesada a fin de identificar una probable coincidencia de contexto usando un modelo estadístico para analizar al menos uno de dichos sucesos y estados de acuerdo con un conjunto finito de instrucciones ponderadas de acuerdo con la probabilidad estadística de sus sucesos correspondientes que ocurren en el estado dado; y proporcionar una instrucción reconocida basada en dichas probables coincidencias acústicas y de contexto.

Abstract: A method and system for improving the speech command recognition accuracy of a computer speech recognition system uses event-based constraints to recognize a spoken command. The constraints are system states and events, which include system activities, active applications, prior commands and an event queue. The method and system is performed by monitoring events and states of the computer system and receiving a processed command corresponding to the spoken command. The processed command is statistically analyzed in light of the system events and states as well as according to an acoustic model. The system then identifies a recognized command corresponding to the spoken command.
