Development has moved to the SpeakEasy-2 organization in order to split the project into multiple repositories.
The MATLAB toolbox and python packages are now available. The toolbox is on the MATLAB file exchange and can be downloaded directly from MATLAB's add-on manager. The python package is on PyPI and can be installed using pip:
pip install --user speakeasy2
The R package can be installed within R from CRAN with:
install.packages("speakeasyR")
