Abstract
An apparatus for detecting user speech comprises a first microphone and at least a second microphone, each operable to generate sound signals with respective signal characteristics. The first microphone is operable to capture a greater proportion of speech sounds of a user than the second microphone. Processing circuitry processes the signal characteristics of the sound signals generated by the first microphone and the second microphone to determine variations in those signal characteristics for determining if the user is speaking.
