For automotive hands-free and speech recognition applications, distributed microphones are often mounted in the car where each of the speakers has a dedicated microphone close to his position. To provide additional control information for further speech enhancement, it is often advantageous to distinguish between the activity of the different passengers. In this contribution speaker activity is identified by the evaluation of the ratios between the powers of multiple speaker-dedicated… CONTINUE READING
