Title: VOCE corpus: Ecologically collected speech annotated with physiological and psychological stress assessments
Issue Date: 2014
Abstract: Public speaking is a widely requested professional skill, and at the same time an activity that causes one of the most common adultphobias (Miller and Stone, 2009). It is also known that the study of stress under laboratory conditions, as it is most commonly done, mayprovide only limited ecological validity (Wilhelm and Grossman, 2010). Previously, we introduced an inter-disciplinary methodologyto enable collecting a large amount of recordings under consistent conditions (Aguiar et al., 2013). This paper introduces the VOCEcorpus of speech annotated with stress indicators under naturalistic public speaking (PS) settings. The novelty of this corpus is that therecordings are carried out in objectively stressful PS situations, as recommended in (Zanstra and Johnston, 2011). The current databasecontains a total of 38 recordings, 13 of which contain full psychologic and physiologic annotation. We show that the collected recordingsvalidate the assumptions of the methodology, namely that participants experience stress during the PS events. We describe the variousmetrics that can be used for physiologic and psychologic annotation, and we characterise the sample collected so far, providing evidencethat demographics do not affect the relevant psychologic or physiologic annotation. The collection activities are on-going, and we expectto increase the number of complete recordings in the corpus to 30 by June 2014.
