have asked if there is prior art in IVR space [was: Re: reCAPTCHA implementation problems]

FWIW I have asked on www-voice if there is an use of audio CAPTCHA in 
IVR applications.

This could help us design the prompting to explain the media choice
and the prompting to explain the CAPTCHA task in the
challenge-medium-selection step in the selectable-modality CAPTCHA
dialog.  Gregory has given us an example text for each of these in
his remarks on the Google dialog.
