Does anyone know of any software for natural language processing that
could be ported to OM/Neo? I really like some of the software that is
available for the PocketPC (MS Voice Commander and Fonix). They both
run and work well on a resource limited platform as well, so it *can* be
done, but both are closed.
Here are a couple of OS engines:
http://www.speech.cs.cmu.edu/pocketsphinx/
http://julius.sourceforge.jp/en_index.php?q=en/index.html
http://xvoice.sourceforge.net/
So I guess, is there already any voice control software planned/worked
on for use in OpenMoko? If not, I'll help out, but can we get a project
up and running?
I have tried sphinx a few times over the last few years (the project has been
around for quite awhile). It never was great for continuous processing like
dictating an email, but it worked fine if you gave it a set of commands and a
limited dictionary.
pocketsphinx is already in openembedded and it compiles fine. OE is currently
using pocketsphinx 0.2.1 and sphinxbase 0.1. The current upstream releases are
pocketsphinx 0.3 and sphinxbase 0.2.1. I bumped the version numbers in the
*.bb files and they still compile fine. Now to actually test them on a neo
someday... ;)
As for xvoice (which looks kind of abandoned), this pretty much sums it up: "In
order to run xvoice, you will need a licensed version of ViaVoice for Linux."
Julius looks very nice, but they only have Japanese models at the moment.
I have also seen, in the long past, one that used the method suggested another
place in this thread: you record a sample and when that sample is later
detected it triggers a script. This is a different approach--no language
models, not speaker independent, etc. But it is also quite flexible and
typically pretty accurate. When I gave it a run years ago, the project I used
sort of looked like a "one off" (e.g. a guy's weekend project later forgotten).
Now if only I could remember it's name... ;)
So, in sum, sphinx is ready today though there are other options. It would be
interesting to hear from other openembedded folks how well sphinx has worked on
200MHz-ish ARM-like processors.
