I'm working on an accessibility app for the visually impaired and was hoping
to use NSSpeechRecognizer.
I've found it extremely difficult to get NSSpeechRecognizer to behave
predictably on my system. Does anyone on the list have experience with this
class & success with the Speech Recognition system preference panel? Any
tips or tricks?
I find that that calibration dialog for the Speech Recognition settings
doesn't work at all for me. I'm using a pretty standard external microphone
(built-in to a Logitech Webcam) with an intel Mac Mini. I can see my signal
just fine and I'm speaking clearly in as accent-neutral a way as I can, and
still none of the test sentences ever highlights. Is a headset mic
typically required, or is there some other gotcha here?
When I give NSSpeechRecognizer a very small and unambiguous command set, I
find it badly misses the mark. For example I might have "Play", "Next", and
"Stop" in my command set, and it will interpret "Next" as "Play", but it
will never interpret "Play" as a command - pretty unusable, I'm hoping it's
just a calibration issue.
One last note - is there any way to do proper dictation with this class or
will it only recognize the preset command list you give it? I'm thinking
for example of prompting for a file name to save to, or a term to search on
- it would be nice to have true dictation, otherwise I'll resort to
providing an alphabet as a command set so the user can spell it out
(assuming I can get that to work).
TIA,
Chris
