This work brings a new perception to intelligent environments for human activity recognition. To understand human activities, we need to differentiate users concerned and their interpersonal links. We propose a new group interaction detection tool based on an assumption that conversational turn taking is synchronized inside groups. We assess HMM-based and algorithmic approaches to build a detector which is able to segment interaction groups from speech detection. Both approaches show good results thus confirm the conversational hypothesis.
