Abstract: In this paper, we propose an approach to detect simultaneous fear emotion and deception behavior from speech analysis. The proposed methodology is the following. First, two separate classifiers to recognize fear and deception are conceived based on adequate voice features using K-Nearest Neighbors’ algorithm. Then, a decision-level fusion based on the belief theory is applied to infer whether the studied emotion and behavior are detected simultaneously or not as well as their degree of presence. The proposed approach is validated on fear/non-fear emotional and deception/non-deception databases separately. Results for separate classifiers reach an accuracy rate in the range of 95% with 24 features for fear recognition and 75% using 8 features for deception detection.
