[BUG] After using SpeechToText my application has an unhandled exception on close

Current Behavior

If I use SpeechToText.Default or register a singleton and use it via DI, I get an unhandled exception in C:\Windows\SYSTEM32\ntdll.dll on closing the application.

This doesn't appear when running a release build but I can see it's still logged to the application event log.

Expected Behavior

No error should occur.

Steps To Reproduce

1. use the StartListeningAsync() method
2. close the project, with or without calling the StopListeningAsync() method
3. observe debugger error and error in application event log

I've attempted a number of methods of stopping/disposing the speech engine before closing, as well as adding via DI. Same error in all instances.
