Hi @jdspates, in fact Tobii Dynavox, our Assistive Eye Tracking business department has already this kind of setup ready for use since some time now.
You can check out their own page @ https://www.tobiidynavox.com/en-gb/support-training/videos/eyemobile-plus/use-voice-recognition-with-eyemobile-plus-and-pceye-plus/
Where some of the technologies in use are discussed. Hopefully this is of some use to you.
