Subject: Win32OLE and SAPI5 voice recognition problem

I stumbled across the ruby library for this while poking around for
something else in RAA, and it seemed interesting. I tried to port
something relatively simple to see if I could get it working...

---

require "win32/sapi5"
include Win32

listener = SpSharedRecognizer.new
context = listener.CreateRecoContext()
grammar = context.CreateGrammar(1)
grammar.DictationLoad

grammar.DictationSetState(1)

ev = WIN32OLE_EVENT.new(context, "ISpRecoContext")

---

... And that last line is as far as it gets, with this error message:

recotest.rb:15:in `initialize': failed to query IConnectionPoint
(RuntimeError)
    HRESULT error code:0x80040200
        from recotest.rb:15:in `new'
  from recotest.rb:15

I don't *think* more initialization is required before being able to
receive events from the object. (At least, it didn't appear to be in the
examples that I looked at.) And I don't think that's the wrong
interface, though with the way the documentation is set up it's hard to
be sure.

In any case, there's something wrong, but I'm not sure what. Anyone have
any ideas? (Alternately, anyone have some working ruby speech
recognition code. Once I have something that works, I can start tweaking
it until I figure out what I'm doing, but without having some kind of
starting point...)
