I tried with comtypes-0.6.1 and 0.5.3 on both Python 2.5.2 and 2.6.2.
I get no output about events from ShowEvents in either case while in
the PumpEvents loop.
To make sure SAPI is set to fire events (which MSDN says it is by
default, but you never know), I also tried setting property
tts.EventInterests to SVEAllEvents. Still, no luck.
As a side note, I do get events when accessing SAPI5 using the
win32com package. Wrapping the SAPI.SpVoice instance with WithEvents
works as expected.
