Design/Make self voicing TTS LCD display for UM2?

[ErikFerret 1]

Hi there,

I am an assistive technology practitioner/Maker/DIY-er/Multimedia artist (not an engineer). I have worked with Printrbot/Repetier/Marlin as an on again off again hobby and now currently, I am working with a relatively new UM2 at work. Because I work in disability services, we are most focused on the creation of Tactile learning objects. However one of the things we are noticing is that while there is a disability presence in the Maker movement in terms of people with disabilities hacking their own adaptive equipment, or people designing things on behalf of people with disabilities but the machines being produced now don't contain accessibility features/universal deign features such as self voicing menus/tactile controls (for starters) . So um, Lets make one!? (ie tts enabled LCD control for UM2) I'm thinking (in my non engineering fantasy brain) Could we not load Festival open source TTS engine (or other open tts engine) into Arduino and attach it to the LCD control? (I'm putting this query out to a few different forums but wanted to start here)

Thanks for your thoughts,

Erik
