[Accessibility_sig] placement of audio captcha in a form

[Bill.Woodland at tbpc.state.tx.us]

I found a nice captcha script written in asp on Bob McKay's freshmango.com 
that used the aspJpeg object (costs money), and I modified it to support a 
FREE image library (overpower library).  That prompted me to finally get 
my audio captcha script working. 

Now I'm ready to use it, but not sure if there's any standard way to 
inform AT users of its presence.  All I'm doing is showing a link to the 
script that generates the audio file.  Here's a test page:

The actual link to the audio is in the label for the verification code 
textbox on the form, but is this the best way to present it?  Would a 
button be easier for AT users to access?  Would it be better placed 
elsewhere?  When in forms mode, would it be confusing to hear that there's 
a link there?
