We've just found the source of occasional crashes and freezes occurring when Microsoft Cognitive Speech-to-text was used. We tested and couldn't reproduce the crashes, so it looks like the problem is fixed. For those of you who are interested, the problem was that the websocket of STT was not synchronized properly with the Scaleform thread.
Remember that speech-to-text is activated by hitting Enter (you can also click the mic icon if you prefer), speak, and then hit Enter again to send the text to our servers. Hopefully you'll have verified that the text says what you meant before hitting Enter again :) If it doesn't, correct it using the keyboard and hit Enter.
