Abstract
An appliance can include a microphone transducer configured to receive sound from an environment and to convert the received sound into an audio signal. The appliance can be configured to receive an input audio signal via the microphone transducer, responsive to an activation input. The appliance can be configured to initiate a bi-directional, wireless communication connection with an external device in parallel with receiving the input audio signal, and responsive to the activation input. The appliance can be configured to transmit an output audio signal corresponding to the input audio signal over the communication connection when the wireless communication connection is established. Related aspects also are described.
