Hold up an "S" hand sort of as if you were holding a microphone.
This is an awkward little sign to be using in the Deaf Community eh?
But quite often our meetings are interpreted for the
"Deaf-Impaired." (That isn't a technical term folks and you
probably won't find it in your Speech Pathology textbook).
When doing this sign it helps to move your mouth around a bit as if
saying something. People generally just mouth or partially mouth the
word "microphone" when doing this sign.
