Speech I/O for Embedded Applications
We've barely scratched the surface of speech user interfaces, even for a checklist application. Depending on your embedded system, you'd have to give the user a way to start and end the checklist app, and ideally you'd have a way of signaling to the user when the app is listening. PocketSphinx prompts with “Listening...” and is supposed to terminate on saying “goodbye” (that doesn't work for me—maybe it's my Texas accent?). The source code for PocketSphinx (labeled continuous.c) comes with the package, so you can experiment with it. There are many, many optimizations you could make to both speech recognition and synthesis, using restricted vocabularies, different voice databases and just tuning the parameters.
And, what about a more general, practical speech user interface for embedded devices? The tools are available—how creative can you be?
