Abstract

A microphone assembly includes: at least three microphones for capturing audio signals from the user's voice, the microphones defining a microphone plane; an acceleration sensor for sensing gravitational acceleration in at least two orthogonal dimensions so as to determine a direction of gravity; a beamformer unit for processing the captured audio signals in a manner so as to create a plurality of N acoustic beams, a unit for selecting a subgroup of M acoustic beams from the N the acoustic beams; an audio signal processing unit having M independent channels for producing an output audio signal for each of the M acoustic beams; a unit for estimating the speech quality of the audio signal in each of the channels; and an output unit for selecting the signal of the channel with the highest estimated speech quality as the output signal of the microphone assembly.
