I today enable speech recognition in windows 10 and after that some of my keyboard keys stopped working. The, i turned off speech option but keys still did not work immediately. but now in the evening, all keys are working fine on my keyboard. What could be the issue? i still cant find the reason for this behaviour.
keys again worked but again stopped. keys which re no working are 3 backspace T 9 Z X B 7
 
Try removing the keyboard in Device Manager, reboot and Windows will reinstall it with drivers. This might work.
 
I have a crazy thought. Your speech recognition resulted in slobbering on the keyboard which temporarily shorted it out, or all that talking made you thirsty, so had a beverage at the workstation and spilled some liquid on it.

Conductive liquid dries, keyboard works again. When several keys suddenly stop working, it is usually all the same keys on one branch of the array connected electrically, and since a different keyboard works as well, that further seems to isolate it to this one keyboard having electrical fouling.

Open it, clean it out, examine for damage, reassemble... or just keep using the new keyboard, and try the malfunctioning keyboard on another system.
