The paper reports acoustic analyses of 1. the pitch, 2. long term average spectra, 3. formants measures performed on speech samples obtainea in the absence and in the presence of cognitive stressors. The results suggest that although pitch is altered only while stressors are apllied, other parameters may exhibit more durable changes, even after disappearence of the stressing agents.
