The Psyche

For Gruphone 2.0 and later, I’ve forked (and heavily customized) the jasper voice response system.  It’s a python framework that glues together a few different text-to-speech engines, and a couple of speech-to-text engines.  I’ve only used the PocketSphinx STT engine on dial-a-grue.  Jasper is very modular and flexible, but I’ve put considerable effort into making it more integrated into the phone hardware.

For Gruephone 1.0, I hacked up the unix ZIP interpreter….. I

• stripped out all code that needed curses(3).
• stripped out the part that did any line formatting and paging.
• compiled it on the chip, so that it is an ARMv7 executable.

I also did something similar with the Colossal Cave Adventure v4 (660 point version).
