Windows 10 Pro version 1803 with Microsoft Speech Recognizer 8.0 for Windows (English - US)
No advanced speech options selected but I did do the brief training exercise upon setup. 

Windows Speech Recognition text is not inserted into Omnibox, etc. by default. However, if you go to chrome://accessibility and check the boxes manually, speech can be inserted. This feature request is for Chrome to detect Windows Speech Recognition and turn on support automatically. 

There are also advanced features that could be implemented. For example saying "press tab" advances focus through the tab order in Edge 42.17134.0, but not Firefox 62.0 and not in Chrome with support manually enabled. However, these may be beyond the scope of our intended support.
