Please help! win32 com_error 'Exception occurred'

[Richard Gordon]

I've got a fatal bug using Parente's pyTTS with Python 2.3 on Windoze 32 using MS SAPI 5.1 and Hammond's win32 module. The test program is
  import pyTTS
  tts = pyTTS.Create()
  tts.Speak('Hello world.')

The resulting debug trace is:

  PythonWin 2.3.5 (#62, Feb  8 2005, 16:23:02) [MSC v.1200 32 bit (Intel)] on win32.

  com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2147201015), None)
  >>> 

The system does not have a sound card --- could that be an issue?

My head is about to explode trying to solve this problem, so your help and suggestions will be much appreciated.
