Abstract:
A headphone, headphone system, and method is provided to enhance speech pick-up from a user of a headphone, by removing noise and echo components. A primary signal is derived from at least one microphone associated with the headphone. The primary signal is configured to include a component of speech from the user. A noise reference signal is representative of acoustic noise in the environment of the headphone. A playback signal is provided by an audio source to be rendered by an acoustic driver associated with the headphone, and an echo reference signal is representative of the playback signal. The systems and methods filter the primary signal to reduce noise and echo components, based on the noise reference signal and the echo reference signal, respectively, to provide a voice estimate signal.

Claim (Index 4):
The method of  claim 1  wherein filtering the primary signal to reduce components correlated to the echo reference signal includes generating an estimated echo signal by filtering the echo reference signal using both a set of initial filter coefficients and a set of adapted filter coefficients, and subtracting the estimated echo signal from the primary signal.
