Abstract
An electronic device (200) includes a user interface (205), a communication circuit (206), and an audio capture device (212) to receive ambient audio signals from an environment about the electronic device. A voice control interface engine (214) is operable with the audio capture device to process signals received from the audio capture device to identify at least some speech from the ambient audio signals. One or more processors (203) are operable with the voice control interface engine to compute a noise index as a function of the ambient audio signals and the at least some speech. The one or more processors can optionally identify a source of the at least some speech. Where the noise index exceeds a predefined criterion, the one or more processors can execute a communication operation on one or more of the user interface or the communication circuit.
