Are there any hacks to force Edge to remember my preferred reading voice and reading speed?

Every few days on each of my devices where I use Microsoft Edge browser, Edge forgets my preferred (i.e., previously selected) reading voice and reading speed settings. Unlike other settings, Edge seems incapable of remembering my reading preferences on any one device yet alone on all of my devices. Consequently, I am wondering if there is a registry hack to specify my preferred reading voice and reading speed? I am quite interested in a solution because Edge reverts/defaults to a voice that I especially dislike.
