I think one of the most exciting things about this project is that once it's all said and done, all Braille Reader devices will be able to read books via speech using OpenEVV and any other synthesizer we want. The Brailliant BI40X, Brailliant BI20X, NLS eReader, Mantis Q40 and Chameleon 20 all contain a SAMA5D3 microchip, running an ARM Cortex-A5 CPU with 256 MB of RAM (~110 available after Baker starts) running at 536MHz, which is more than enough for speech to keep up rather nicely. Especially exciting for eReader users, where your previously inert headphone jack will make this possible there, too.
