[asterisk-speech-rec] has anyone got a voice recognition active/processing sound?

[Steve Prior]

When I call some voice recognition systems they have a "bloopy" sound 
that is played either when the system is waiting for speech or when it 
is processing some speech.  Lumenvox didn't come with one and Asterisk 
itself doesn't provide anything, so I was wondering if anyone else had 
already come up with something?
