Emotion Recognition ToolKit (ERTK): Standardising Tools For Emotion Recognition Research

摘要

Many software packages and toolkits have been developed for machine learning, in particular for natural language processing and automatic speech recognition. However, there are few software packages designed for emotion recognition. Emotion datasets have diverse structures and annotations, and feature extractors often have different interfaces, which requires writing code specific to each interface. To improve the standardisation and reproducibility of emotion recognition research, we present the Emotion Recognition ToolKit (ERTK), a Python library for emotion recognition. ERTK comprises processing scripts for emotion datasets, standard interfaces to feature extractors, and a framework for defining experiments with declarative configuration files. ERTK is modular and extensible, which allows for easily incorporating additional models and processors. The current version of ERTK focuses on emotional speech, however, the library is modular and can be easily extended to other modalities, which we plan for future releases. ERTK is open-source and available from GitHub: https://github.com/Strong-AI-Lab/emotion.
