Abstract
An apparatus is configured to rest on a wearer's neck or shoulders, and has a first microphone positioned at a first position located on the right side of the wearer, when the apparatus is worn, and a second microphone positioned at a second position located on the left side of the wearer. A processor receives audio signals output by the first and second microphones, and compares the audio signals from the first microphone to the audio signals from the second microphone. Based on the comparison, the processor determines whether the wearer's head is rotated to the right, left, or center, during an instance of the user speaking. Based on the determination, the processor selects a first one of at least two audio signal destinations, and provides the audio signal from at least one of the microphones to the first selected audio signal destination.
