Firewall Sys32\Speech_OneCore\Common\SpeechModelDownload.exe?

I went downstairs for 5 mins and when I come back C:\Windows\System32\Speech_OneCore\Common\SpeechModelDownload.exe is requesting access. Google search did not return any useful info.  Does anybody know what this is and why it is running randomly. Also, if I should allow or deny it? 

Note: My computer goes to the lock screen after 3 minutes of inactivity. This showed up after I logged back in.


Thank you.

The file C:\Windows\System32\Speech_OneCore\Common\SpeechModelDownload.exe seems to be a legit file in Windows from Microsoft.

The file sounds like a part of Cortana (the AI assistant in Windows 10) and might be speech recognition rule downloader in order to improve Windows speech accuracy.

If you have any suspicion, I would recommend you to upload it to VirusTotal and check. (Click 'Browse' and enter "C:\Windows\System32\Speech_OneCore\Common\SpeechModelDownload.exe" without quotes and click 'Open' and click 'Scan it' button.)

Alright, based on what you've suggested, I will assume it was started as some type of automatic update and will forget about it.

I set the rule to deny, but since the Virustotal scan showed up as clean, I guess I will go ahead and delete the rule I made.
I have a question though. How come some files have no signature, even though they are obviously made by Microsoft(Sticky Notes or System for example),
 

What I learned :

--Virustotal > wasting other peoples time asking

--A google search of Speech_OneCore returned an article(I skimmed over it) written a couple years back discussing OneCore and how it would allow you to use your Xbox/Windows Phone on your PC and how the next windows might be called Windows One (obviously it wasn't). They were right about the Xbox and Phone things, because insiders can get their phone notifications inside of windows if you download the Cortana app on your apple/robot/window. That seems pretty cool being able to see your texts while your phone is in the other room or you are wearing headphones. 

Sorry, I lost the reply note.

Are you sure that the System date is correct?

Please make sure you have manually synced it with the time server of your choice.

Also, try resetting internet explorer advanced settings. (Type inetcpl.cpl in 'run' window > 'Advanced' tab)

Tick the 3  Check for  under the Security section of same 'Advanced' tab.

Make sure to restart and check.
