Table 1 UT-SCOPE-physical speech corpus: details of corpus including speakers, audio, sessions, and transcription effort. The corpus is used for speaker ID and stress classification for two stress conditions: cognitive stress and physical stress. The cognitive load is simulated by having subjects play a driving game on an interactive game console. The physical stress is induced by requiring subjects to maintain a 10-mph pace based on visual speed display on an elliptical stair-stepping machine
