Abstract
An electronic device, a system, a method, and a program for externally adding voice control functionality to another device are disclosed. The electronic device includes memory, a processor, an audio input interface, a first communication interface, a second communication interface, and an audio encoder. First return audio data is received by the first communication interface from a sink device. An audio signal corresponding to a voice command is received by the audio input interface from a transducer. The audio signal is encoded by the audio encoder to obtain second return audio data. The second return audio data is output by the second communication interface to a source device. The second return audio data is encoded by an audio encoder of the source device to obtain control data. A function of the source device is controlled based on the control data.
