A microphone array is used in a speech recognition system for a high S/N sound capture.
The high S/N sound capture can be achieved by forming a directivity pattern of the microphone array.
In this study, the directivity pattern is designed by using the linear semi-infinite programming method.
Under a real situation, it is assumed that the sound source is moving. Therefore, an accelerated redesign of the directivity pattern is required.
In this paper, the accelerated redesign method based on the directivity pattern before the moving is proposed.
Several redesign examples are shown to present the effectiveness of the proposed method. |
