Detection of Stress by Voice: Analysis of the Glottal Pulse.

reportActive / Technical Report | Accession Number: ADA309684 | Open PDF

Abstract:

An Independent Exploratory Development IED study was performed to determine whether or not significant measures are present in the human voice for detecting the emotional reaction, stress. A technique was implemented for automatically measuring parameters of the glottal pulse, to see which might be indicators of stress. The results of this IED study confirmed that several of the measures are significant indicators of stress for example, the glottal pulse generally narrows or shifts in mass under stress. And although pitch and beta-function parameters were significant across speakers, the measures were largely speaker dependent.
