By the way, I have retitled this topic to, "Unspoken Add-On, Ported to python 3, compatible with NVDA 2019.3 & later" so that the subject matter is entirely clear and it's easier to find in archive searches. Please post any ongoing responses using this message, or another with the new title, as the base for the response.
