Abstract
This paper presents a sound source localization system that composes a wireless microphone array named Jellyfish-02 and robot audition software HARK. Jellyfish-02 surpasses existing microphone array in design and usability, because it has a cover with rechargeable battery, which can be connected to wireless network. We evaluated sound source localization performance of Jellyfish-02, and investigated the percentage of speech overlapped periods in natural conversation. Prom the results, Jellyfish-02 is potentially applicable for assisting group conversation by measuring duration of speech for each participant.
