Siri is not working on my iPhone!!

[iMore Question]

Siri is not working on my iPhone since upgrading to ios9. Siri does not appear to hear my voice input. Help please fix.

Disable Siri and enable it again. I don't know if this is the fix but it's worth giving a try.

If above doesn't work try a reboot by holding power button and home button until you see the Apple logo. Let go and phone will reboot.
