AccessViolationException at SpeechLib.ISpeechVoice.Speak

[Telorast]

I recently upgraded from 2.3.0.8 to 2.3.1.1b and now VC keeps crashing.
I'm trying to run a SpeakSync command and half the sentence will be read correctly, then the crash happens.

The last entry in the logfile is:

I don't get any crash logs in VC folder.

I have tried doing a fresh install in a different folder as well as testing with both 32b and 64b versions. Also tried 2.3.1.0 but same problem.

Reinstalling 2.3.0.8 fixes the problem so I'll just stay there for now.

Hmm.  That's a tough one.  I'm using 2.3.1.1. and do not have that issue.

Can you send me the command XML please.

Are you using the SP version?

Which TTS engine and voice are you using?  Have you tried with different voices?

Are you running VC in a dropbox?  I don't know if that is a problem or not, except that it will be uploading your log files all the time.

[Telorast]

I usually don't have logging active to avoid them being uploaded. I just like the automatic version control of the configuration files.

I was playing around with a fresh install to see if I could find the minimum required configuration to reproduce the problem but after a few crashes I'm having trouble reproducing the problem even with the original configuration files. Maybe some faulty Windows setting I accidentally fixed in the process?

Since it's currently working I'll just leave it alone for now and do some more testing if the problem returns.

[jitterjames]

I hope you fixed it for good.  That sort of thing can be difficult to diagnose.  Let me know if I can help.
