The present invention relates to a wireless, voice-activated remote control device for controlling an electronic device having voice control circuitry. A short-range range wireless data and voice communication link, for example using Bluetooth technology, is established between the remote control device and the electronic device. To activate voice control circuitry in the electronic device, a user supplies an input to the remote control device. In response to the user input, wireless link circuitry within the remote control device sends a control signal, for example an AT command, to the electronic device. The electronic device receives the control signal and transmits a control signal indicating the status of the electronic device. Once the voice control circuitry is activated, the user provides a voice command to the remote control device. The remote control device transmits the voice signal to the electronic device over the wireless communication link. The electronic device processes the voice signal in the voice control circuitry and generates instructions in response to the voice signal if recognized. The voice control circuitry is advantageously located within the electronic device and not within the remote control device to simplify the remote control device and to minimize the amount of power dissipated in the remote control device.
