Abstract

In this paper, we propose a method for synchronizing asynchronous channels in an ad-hoc microphone array based on single source activity for speech enhancement. An ad-hoc microphone array can include multiple recording devices, which do not communicate with each other. Therefore, their synchronization is a significant issue when using the conventional microphone array technique. We here assume that we know two or more segments (typically the beginning and the end of the recording) where only the sound source is active. Based on this situation, we compensate for the difference between the start and end of the recording and the sampling frequency mismatch. We also describe experimental results for speech enhancement with a maximum SNR beamformer.
