Exploring the Benefits of Discretization of Acoustic Features for Speech Emotion Recognition

Thurid Vogt, Elisabeth André

Universität Augsburg, Germany

We present a contribution to the Open Performance subchallenge of the INTERSPEECH 2009 Emotion Challenge. We evaluate the feature extraction and classifier of EmoVoice, our framework for real-time emotion recognition from voice on the challenge database and achieve competitive results. Furthermore, we explore the benefits of discretizing numeric acoustic features and find it beneficial in a multi-class task.
