Abstract
An oven that is controllable by a conversational style voice interaction with a user. It includes voice recognition system for listening to the user and a speech synthesizer for talking to the user. Operation occurs initially in a first voice recognition mode for recognizing one of a group of possible first voice commands from the user. After recognizing a particular first voice command, operation continues in a voice synthesizing mode wherein the user is asked to make some choices which confirms or "narrows" the first voice command. After synthesizing, operation continues in a second voice recognition mode for recognizing a particular one of a second group (less in number than the first group) of possible second voice commands from the user. After recognizing a particular second voice command, the oven operates according to the preprogrammed instructions corresponding to the first and second voice commands.
