EmoVoice is a set of tools, which allow you to build your own real-time emotion recognizer based on acoustic properties of speech (not using word information).




Make sure Visual Studio 2015 Redistributable is installed on your machine. Then run install.cmd to download core binaries and install an embedded version of Python.

If you plan to extract SoundNet features, you will also have to execute install_tensorflow.cmd and download the file sound8.npy into the chains folder.
