Windows speech-to-text blocks indefinitely until application restart

[Spiess]

Windows speech-to-text often stops working after only a few minutes of runtime, blocking indefinitely on requests to stop.
Attempting to dispose the DictationRecognizer in this state causes the entire application to freeze.

Proposed solutions

• Investigate source of problem and fix
• Replace with alternative online speech-to-text (potentially request limited)
• Replace with on-device solution (e.g. DeepSpeech)

Sustainable open-source solutions should be preferred.
