A method of executing operations in a voice-activated command system includes automatically initiating execution of a default operation. A user is then prompted, after the default operation has been initiated, to determine whether the user wishes to execute a second operation instead of the default operation. If the user wishes to execute the second operation instead of the default operation, execution of the default operation is terminated and execution of the second operation is initiated. In voice-activated and other command systems, such as voice dialing systems, this method allows the command system to execute the most probable operation without delay, while still making the system easily navigable by naive users. Systems, computer readable medium and apparatus which implement the methods of the present invention are also disclosed.
