Re: CMU Sphinx Speech Recognition

Thanks for all the info. I don't know how ViaVoice for linux slipped
under my radar.

But I think the various GPL'd linux speech recognitions, Sphinx, and
ViaVoice are like apples and oranges.  Correct me when I'm wrong here,
but for a wearable application a comparison might look like the
following:

             linux   status    system req.   open/GPL   corpus variable
  freespeech   y    pre-alpha      ?            y             ?
CSLU toolkit   n      beta         ?            y             y
MSstate ISIP   y     alpha         ?            y             y
      Sphinx   y     alpha      variable        y             y
    ViaVoice   y     stable      high           n             n?

It seems to me the two critical criterion for incorporating speech
recognition into a wearble, are low system requirements and variable
corpa so you can fine tune the system to only respond to a small
vocablulary. This would make the system more compact, responsive, and
reduce processing time and memory.  Okay, there's only one requirement.
:) I don't think ViaVoice will let you configure it with a smaller
vocablulary, since it's focus appears to be dictation. Although, I'm
probably wrong since there is info about configuring ViaVoice for
applications and there's probably a way to specify the vocabulary.

Hm, so maybe these are really pretty close to one another.  But ViaVoice
definitely has larger system requirements. Most of the GPL'd software is
less then 5MB including the dictionaries, and ViaVoice wants 100MB.
