A voice-operated control circuit and method for using the voice-operated control circuit in connection with a toy vehicle. The voice-operated control circuit contains an audio detector, such as a microphone, to detect audible sound signals, and an integrated circuit that determines the duration of the audible sound signals received by the audio detector. At a user-defined time and based on the audible sound signals received, the integrated circuit determines and controls the duration of operation of various components of the toy vehicle, such as a motor, lights and/or sounds. |
