Anyone using voice recognition for accuracy feedback?

[Catherine Smith]

Hi Michiel,

We're doing this online, as we need vocal response feedback that is
comparable to motor response feedback. Our last hurdle is connecting
individual "dictation profiles" for each subject to the recognition
routine.

Subjects will train the system on their unique pronunciation of "yes"
and "no", which is easy to do. This creates a "voice profile" for the
subject. Hopefully with just a little code tweak we can use the unique
profile in the experiment.This will make the response detection much
more reliable. We're also still trying to perfect timing issues, but
we're optimistic that it will work well.

We're happy to hear that this will be useful for others. We'll share
it when we get it running!

Best,
Cathy
