Pykaldi: A Python Wrapper For Kaldi

We present PyKaldi, a free and open-source Python wrapper for the widely-used Kaldi speech recognition toolkit. PyKaldi is more than a collection of Python bindings into Kaldi libraries. It is an extensible scripting layer that allows users to work with Kaldi and OpenFst types interactively in Python. It tightly integrates Kaldi vector and matrix types with NumPy arrays. We believe PyKaldi will significantly improve the user experience and simplify the integration of Kaldi into Python workflows. PyKaldi comes with extensive documentation and tests. It is released under the Apache License v2.0 with support for both Python 2.7 and 3.5+.
