I'm trying to get Text-To-Speech included within the python-pyqt package.

It looks like the definition is simply missing a declaration for qtspeech (patch attached).  I updated the definition, the package builds, and I'm now able to import the QtTextToSpeech module.  However, I'm not able to find an engine, so I can't verify that it's working 100%.

To validate the new pyqt functionality, I'm trying to get TTS working using the python-pyside-2 package.  That definition already has qtspeech included and I assume it works.  Unfortunately, I can't get that to work either.

I've installed speech-dispatcher, espeak, espeak-ng, and festival.  I'm able to get TTS from the command-line (i.e. spd-say, speak, etc.).  However, no voices or engine are found by PyQt or PySide.  I've verified that the same program works on a separate Debian machine.  Is there some setup for speech-dispatcher that I'm missing?
