1. An apparatus to be worn on a user's wrist, comprising:
a wrist wearable device, the wrist wearable device is configured to be worn on the user's wrist, the wrist wearable device having a plurality of receive orientations;
a first microphone, the first microphone has a first response pattern, the first microphone is coupled to the wrist wearable device, the first microphone is positioned on the wrist wearable device to receive a voice signal from a user when the wrist wearable device is on the user's wrist;
a second microphone, the second microphone is coupled to the wrist wearable device, the second microphone and the first microphone are separated by a distance on the wrist wearable device such that a first distance between the first microphone and the user's mouth is less than a second distance between the second microphone and the user's mouth when the wrist wearable device is in a first receive orientation; and
logic, the logic is configured to:
a. determine a receive orientation of the wrist wearable device by comparing a first signal-to-noise ratio of the first microphone and a second signal-to-noise ratio of the second microphone; and
b. select a main microphone and a reference microphone for the receive orientation.
