Abstract
A portable voice capture device having an orientable arm comprising a first leg and a second leg, the first leg and the second leg having different orientations, the first leg of the first arm comprising a first differential linear array of microphones, a directivity of the first differential linear array being arranged for improved sensing of voice from a user, the second leg of the arm comprising a second differential linear array of microphones, a directivity of the second differential linear array being arranged for improved sensing of noise from a different than the direction of said sensed voice, and a noise reduction circuit for providing a voice signal with reduced noise, based on the output of the first array and on the output of the second array.
