ABSTRACT:
A method for automatically confirming verbal commands issued by a user and received by an automatic speech recognition system. Each verbal command is associated with a command operator set in which one or more command operators are stored. After the user vocalizes a recognized verbal command, the automatic speech recognition system awaits vocalization of a valid command operator from an associated stored command operator set for a pre-determined period of time. During this waiting period a non-intrusive indicator such as a light or a low volume tone notifies the user that the automatic speech recognition system is awaiting or ready to receive an appropriate command operator. If the user vocalizes a valid and recognized command operator during the waiting period, then the automatic speech recognition system executes the verbal command using the command operator and issues a confirmation to the user that the verbal command has been executed. Otherwise, the automatic speech recognition system returns to its idle state awaiting a further verbal command.
