In this study, we investigate how the behavior of the spatial cepstrum changes by the sound source and the movement of the microphone.In recent years, asynchronous distributed microphone arrays have been extensively studied because of the spread of devices such as smartphones and tablets that can easily record speech.Also, the spatial cepstrum which extracts the spatial pattern of each sound source is proposed.The spatial cepstrum can estimate the spatial pattern only from the sound source signal obtained by the asynchronous dispersion microphone array.However, the detailed experiments on the spatial pattern have not been carried out, and what kind of behavior the spatial cepstrum does is not shown.In this study, we confirm the robustness of the space cepstrum when the sound source or the microphone position changes. |
