Great news, Stream Closed Captioner users can now use Microsoft Edge! Now that Edge has officially added support for Speech Recognition, it allows for Stream Closed Captioner to use it for Closed Captions instead of Google Chrome. This is a welcomed change for those that didn't want to use Chrome, now there is at least one other alternative to use.

I have yet to do a full test on how well the speech recognition accuracy is compared to using Google's Speech Recognition service. But it appears to get everything (mostly) right.
