Language: Python 2.7

• pyAudioAnalysis for short time features extraction
• scikit-learn for preprocessing, classification and validation

• Berlin Database of Emotional Speech [1]
• DaFeX Dataset [2-3]

Download Berlin DB from the link. Request DaFeX dataset following the link instructions. The code will generate automatically .wav files

Example:

python emorecognition.py -d 'berlin' -p [berlin db path] -e -l

The first time you run the application, -l and -e options are mandatory because you need to extract data and features. Every time you change the feature extraction method and/or the dataset data you need to specify -e and/or -l to update your .p files.
