Is there a way to make Mirc interact with windows built-in vocal synthesis (eg. Microsoft Sam or whatever else is installed)?

I don't mean to do it in the usual way (with the agent) but like this:

I send to "nick" a special CTCP (e.g. /ctcp nick SPEECH hey, how you doin?).

nick's Microsoft Sam (or whatever else installed in nick's PC) says "hey, how you doin?".

How can I get this stuff work? Thanks a lot
