The wireless telephone includes a first microphone, a second microphone, and a signal processor, wherein at least one of the first microphone and the second microphone is a uni-directional microphone. The first microphone outputs (201) a first audio signal that includes a voice component and a background noise component. The second microphone outputs a second audio signal (202). The signal processor increases a ratio of the voice component to the noise component of the first audio signal based on the content of at least one of the first audio signal and the second audio signal to produce a third audio signal.
