I see you have rather old version of gnome-speech. Currently OAFIID has proto0.3 not 0.2. Probably upgrade can help. Also there is test-speech.c in gnome-speech/test directory. Try it first, it contains similar activation code and should work.

Anyhow I don't think that problem is in the client code. It's likely you have some problems with bonobo or festival server, try some debugging on it. You can explicitely start server binary under debugger and with enabled BONOBO_ACTIVATION_DEBUG and BONOBO2_DEBUG=all and then safely run client.
