speech emotion recognition using a convolutional recurrent networks based on IEMOCAP

speech-emotion-recognition

TensorFlow implementation of Convolutional Recurrent Neural Networks for speech emotion recognition (SER) on the IEMOCAP database.In order to address the problem of the uncertainty of frame emotional labels, we perform three pooling strategies(max-pooling, mean-pooling and attention-based weighted-pooling) to produce utterance-level features for SER. These codes have only been tested on ubuntu 16.04(x64), python2.7, cuda-8.0, cudnn-6.0 with a GTX-1080 GPU.To run these codes on your computer, you need install the following dependency:

• tensorflow 1.3.0
• python_speech_features
• wave
• cPickle
• numpy
• sklearn
• os

Demo

For running a demo, after forking the repository, run the following scrit:

      python zscore.py

      python ExtractMel.py

      python model.py

Note

There are some little differences betweem the implementation and the paper, eg.when run python model.py, you will find that the recognition rate of happy is very poor, which is caused by the imbalance of the training samples. An effective method is to use the happy sample twice.
