This research explores the various indicators for non-verbal cues of speech and provides a method of building a paralinguistic profile of these speech characteristics which determines the emotional state of the speaker. Since a major part of human communication consists of vocalization, a robust approach that is capable of classifying and segmenting an audio stream into silent and voiced regions and developing a paralinguistic profile for the same is presented. The data consisting of disruptions is first segmented into frames and this data is analyzed by exploiting short term acoustic features, temporal characteristics of speech and measures of verbal productivity. A matrix is finally developed relating the paralinguistic properties of average pitch, energy, rate of speech, silence duration and loudness to their respective context. Happy and confident states possessed high values of energy and rate of speech and less silence duration whereas tense and sad states showed low values of energy and speech rate and high periods of silence. Paralanguage was found to be an important cue to decipher the implicit meaning in a speech sample. © 2014 Springer Science+Business Media New York. Source

Bias in Human Behavior | Year: 2012

One of the major goals of side bias is to understand the relationship between the functioning of the brain and a person's behavior. Often at times it becomes difficult or unethical to directly study the nervous system during a behavior and therefore indirect methods are used instead. This book has many facets, many explanations, many techniques and many unanswered questions and scope for future research. This book intends to address each of these issues so that a comprehensive reading of the subject matter is made available to academicians, researchers, and other interested in this issue. © 2012 by Nova Science Publishers, Inc.

The article discusses a study that focused on interpersonal needs and investigated whether interpersonal behavior of Antarctic personnel deteriorated after the halfway point of prolonged isolation and confinement. Twenty-three personnel who resided in Antarctica for 14 months served as participants. The mean age of participants was 39 years (SD = 8.7 years). This study uses the FIRO-B questionnaire that assessed the dimensions of interpersonal behavior. The findings indicate a greater need to associate with other personnel but with less intimacy. Inversely, personnel want others to establish close relationships with them but with a low level of interaction. Besides, the overall interpersonal behavior (the mean score of six scales of FIRO-B) reveals a significant improvement in the first versus the second half of a prolonged isolated and confined environment. © 2010 SAGE Publications.
