How do I enable the microphone on the Surface Pro 4 (touch) keyboard?

Question

Having used an iPad and Android for several years with their excellent speech recognition available from the microphone of the on-screen keyboard, I'm stumped that I can't find the same thing on my new Surface Pro 4!

Is it possible to have arbitrary voice input available via the virtual keyboard, as with iOS and Android?

Edit: Cortana is working, and the voice recognition is excellent with it.

Solution

Finally!? Discussed at https://www.engadget.com/2018/04/27/windows-10-s-next-major-update-arrives-on-april-30th/:

Other notable features include tweaks to Microsoft Edge, such as tab muting and autofill on web payment forms, and updates to Dictation. Instead of seeking out the voice input app, you'll now be able to capture spoken word in any text field simply by pressing Win+H

I just typed windows H and this text is now being recognized as I speak it.
