Speaker independent emotion recognition

Speech Emotion Recognition

This repository contains our work on Speech emotion recognition using emodb dataset. This dataset is available here Emo-db

Prerequisites

Linux (preferable Ubuntu LTS). Python2.x

Installing dependencies

Note: You can skip this step, if you are installing the packages. Dependencies are listed below and in the requirements.txt file.

• h5py
• Keras
• scipy
• sklearn
• speechpy
• tensorflow

Install one of python package managers in your distro. If you install pip, then you can install the dependencies by running pip3 install -r requirements.txt

If you prefer to accelerate keras training on GPU's you can install tensorflow-gpu by pip3 install tensorflow-gpu

Directory Structure

• speechemotionrecognition/ - Package folder which contains all the code files corresponding to package
• dataset/ - Contains the speech files in wav formatted seperated into 7 folders which are the corresponding labels of those files
• models/ - Contains the saved models which obtained best accuracy on test data.
• examples/ - Contains examples on how to use the package

Details of the package

• utilities.py - Contains code to read the files, extract the features and create test and train data
• mlmodel.py - Code to train non DL models. We have three models
  • 1 - SVM
  • 2 - Random Forest
  • 3 - Neural Network
• dnn.py - Code to train Deep learning Models. Supports two models given below
  • 1 - CNN
  • 2 - LSTM

Examples

Have a look at examples/ directory. ml_example.py has examples using ML models. cnn_example.py and lstm_example.py has examples using cnn and lstm models.
