Technical Report: a tool for measuring Prosodic Accommodation

Social interaction is a dynamic and joint activity where all participants are engaged and coordinate their behaviour in the co-construction of meaning. It is observed that conversational partners adapt their pitch, intensity and timing behaviour to their interlocutors. The majority of research has focused on its linear manifestation over the course of an interaction. De Looze et al hypothesised that it evolves dynamically with functional social aspects. In the work of De Looze et al, they proposed through their praat based feature extraction and matlab based visualisation that one can visualise prosodic accommodation at the positive correlation threshold values. and the capture of its dynamic manifestation. Here we seek to build a complete system for measuring prosodic accommodation with matlab. This work uses data collected in a pilot training scenario where senior pilot and co-pilot are engaged in conversation during the flight. Additionally, we use the data from a ship wreck task by two pilots. We also attempt to evaluate this measures of accommodation with ground truth labels given by a trainer of Crew (or sometimes Crisis) Resource Management (CRM).
