  • Speech dialog method and device
    Publication number: 20070055524
    Abstract: An electronic device (200) for speech dialog includes functions that receive (205, 105) an utterance that includes an instantiated variable (215), perform voice recognition (210, 115, 120) of the instantiated variable to determine a most likely set of acoustic states (220) and a corresponding sequence of phonemes with stress information (215), determine prosodic characteristics (272, 274, 276, 130) for a synthesized value of the instantiated variable (236) from the sequence of phonemes with stress information and a set of stored prosody models. The electronic device generates (335, 140) a synthesized value of the instantiated variable using the most likely set of acoustic states and the prosodic characteristics of the instantiated variable.
