Driver Emotion Profiling from Speech - Digital Signal Processing for In-Vehicle Systems and Safety - page 27

2.4 Summary, Conclusion, and Future Work
Speech emotion profiling can be an effective tool for investigating intra- and
inter-cultural variations from various perspectives. It enables one to visualize the
interaction of the emotion that may give important information which is not
observable using normal signal analysis tools, namely, the speech recognition and
speaker identification. More work in understanding the profile especially in
extracting the relevant features as well as the appropriate data processing are
needed to benefit from such visualization tool. The speech emotion profile coupled
with a three-dimensional affective-space model may be able to provide a better
understanding of the dynamics of driver behavior. This work also illustrated that
there are strong correletions between driver behavior and emotion which can be
emperically measured using speech signals.
