In this paper we introduce a voice capture application using a wireless sensor network; our main contribution is the integration of a novel capture technique specifically designed for hierarchical wireless sensor networks. Furthermore, we show the challenges involved in the implementation of our experimental prototype which is oriented towards a secure ubiquitous home environment but could be extended to other similar scenarios. We performed a series of experiments on our prototype implementation, the results of those experiments showed that our approach consumes less energy than the traditional capture and send approach. Additionally, our technique provides basic security services such as authentication and confidentiality for control messages without incurring in additional energy consumption.
