Diagonal microphone placement for the landscape/portrait interchangeable mode of a personal computer

Abstract

This paper proposes diagonal microphone placement for the landscape/portrait interchangeable mode of a personal computer. Two microphones are diagonally located at a screen corner to provide useful directivity for target-signal enhancement in both landscape and portrait modes. The diagonal microphone placement guarantees a nonzero microphone spacing in either the landscape and the portrait mode along the ground surface leading to successful interference attenuation. Evaluations in a speech recognition scenario demonstrate that the diagonal microphone placement is effective in both the landscape and the portrait position with comparable command recognition rates of 80 to 99%.
