Does anyone know of philosophical work done on & #39;silence& #39; as a speech act?

I don& #39;t mean the act of silencING someone else: I& #39;m thinking about a conversational exchange where A speaks to B and B chooses to stay silent (though it would be natural to assume that B /should/ speak).

Something like a "performative silence," maybe?

Or (from a different perspective) the greatest possible flouting of Grice& #39;s maxim of quantity?

It seems like such actions are nonetheless communicative and, as such, could influence the conversational scoreboard.

My literature searches keep coming up with epistemic-injustice-type stuff which, though important, is just not what I& #39;m looking for right now! (I don& #39;t think?!)

Anyway, help would be greatly appreciated!
