Title: Automatic Conflict Detection in Police Body-Worn Audio,
Abstract: Automatic conflict detection has grown in relevance with the advent of
body-worn technology, but existing metrics such as turn-taking and overlap are
poor indicators of conflict in police-public interactions. Moreover, standard
techniques to compute them fall short when applied to such diversified and
noisy contexts. We develop a pipeline catered to this task combining adaptive
noise removal, non-speech filtering and new measures of conflict based on the
repetition and intensity of phrases in speech. We demonstrate the effectiveness
of our approach on body-worn audio data collected by the Los Angeles Police
Department.
