RTDS: Real-Time Discussion Statistics

RTDS: Real-Time Discussion Statistics

Abstract

We present RTDS, an Android application to analyze discussions while they are taking place. Using two microphones of a smart phone and Time Difference of Arrival measurements, conversations of participants are evaluated regarding, e.g., speaking time, contributions, or complex interaction patterns. The application can also assume the role of an active referee to ensure that all speakers get a fair share of the ongoing conversation. By using an off the shelf smart phone with two microphones, our system can immediately be applied to track spoken interactions between people. Experimental results show that our implementation causes only 2% user classification errors whilst being able to run in real-time on a standard smart phone without hardware modifications
