Reverberant environments pose a challenge to speech acquisition from distant microphones. Approaches using microphone arrays have met with limited success. Recent research using audio-visual sensors for tasks such as speaker localization has shown improvement over traditional audio-only approaches. Using computer vision techniques we can estimate the orientation of the speaker's head in addition to...
This paper provides an overview of the area of automated dominance estimation in group meetings. We describe research in social psychology and use this to explain the motivations behind suggested automated systems. With the growth in availability of conversational data captured in meeting rooms, it is possible to investigate how multi-sensor data allows us to characterize non-verbal behaviors that...
