Tobi
I updated to 0.6.3.0 on a PC with speech installed: no problem. But on a PC without synthetic speech, the installation of Tobi fails. I've included the log file.

Thank you for reporting ! The actual error is: No voice installed on the system or none available with the current security setting. at System.Speech.Internal.Synthesis.VoiceSynthesis.GetEngineWithVoice(TTSVoice defaultVoice, VoiceInfo defaultVoiceId, String name, CultureInfo culture, VoiceGender gender, VoiceAge age, Int32 variant, Boolean switchContext) at System.Speech.Internal.Synthesis.VoiceSynthesis.GetVoice(Boolean switchContext) at System.Speech.Internal.Synthesis.VoiceSynthesis.CurrentVoice(Boolean switchContext) at System.Speech.Synthesis.SpeechSynthesizer.get_Voice() at Tobi.Plugin.AudioPane.AudioPaneViewModel.OnSettingsPropertyChanged(Object sender, PropertyChangedEventArgs e) I wonder how I could reproduce this error on my machine...it looks like I'd need to remove all the built-in SAPI voices. I'll get back to you on that. PS: I detached the log file from your post as this is a public forum and the Tobi log file contains the IP address of the machine it is running on. Regards, Daniel

Note to users who experience this problem: you can go to your Windows "Control Panel" -> "Uninstall Application" and from there when you select Tobi you should be able to rollback to the previous version 0.6.2.0 (if you previously installed it, obviously). I will commit a bug fix shortly. Regards, Daniel

Although I haven't been able to test it on my machine, there is now a fix for this crash (basically, we now ignore missing SAPI voices). It will be pushed into the next application update (this week). Regards, Daniel

Thanks for the info, the problem is hard to recreate i think: In the Control panel, the icon "speech" is there but unavailable, no response. I really don't know how this is possible. I tried to install a Sapi voice, but still the speech icon is not responding. I rolled back Tobi to 0.5.0, but now it isn't updating any more :-( Maybe I better remove Tobi first and wait for the update.

Tobi v0.6.4.0 is available via online updates. Please let me know if the new TTS / SAPI workaround works. Many thanks for your feedback, Daniel

The workaround for the missing Sapi voice works, thanks, I can now update. Is it possible that there is something wrong in the registry, like was mentioned in another post about TTS voices?

In reply to: " Is it possible that there is something wrong in the registry, like was mentioned in another post about TTS voices? " Well, because SAPI 4 TTS voices are deprecated, Tobi simply cannot "see" them, so they are probably not the cause of a crash. The crash that you discovered is when Tobi attempts to get the currently active Windows voice, an exception is generated at this point and it seems to be a deep system problem, maybe the registry or some kind of erroneous security setting in Windows. Anyway, what happens now that I have implemented a workaround, can you actually use the TTS feature or is it completely disabled because of the voice selection problem ? Many thanks !! Daniel

Te TTS feature is not disabled, and in "audio-settings" the Microsoft Sam" voice can be selected? But it doesn't work. I think it is a Windows problem, because the icon "speech" in Control Panel is not responding. But no problem, Tobi is working again.
