Spectrum-related variabilities in stressed speech under laboratory and real conditions

Robert Ruiz, Emmanuelle Absil, Bruno Gramatica, Bernard Harmegnies, Claude Legros, Dolors Poch

Emotional stress induced by various types of situations leads to vocal signal modifications. Previous studies have indicated that stressed speech has a higher fundamental frequency Fo and presents noticeable changes in the spectrum of vowels.

In this paper, spectrum-related variations are studied. All the corresponding spectrum-related indicators are applied to stress detection in a laboratory situation (Stroop's psychometric stress test) and a real situation (Cockpit Voice Recording) inducing emotional disturbances.
