cannot unlock my phone !!

I have a samsung Galaxy S3 mini
I installed swiftkey keyboard..
I locked my phone with a password
and everything was working perfectly,
Now that someone has accidentally tried to unlock my phone and again accidentally tried to type the password.. and finally accidentally pressed on the microphone button,
since then I cannot unlock my phone,
the Wi-Fi was turned off so I cannot connect to the internet , even though when mobile data is turned on, I cannot connect to the internet as long as the screen is locked!
I cannot even pull down the notification bar
and all I have when I swipe the screen is "speak now" typed under the microphone sign with a "waiting for results" above them and a loading sign !
I tried rebooting the phone tens of times and also I tried pulling the battery and the external SD-CARD... any help?
Thank you,
oh and No, my phone is not rooted.
Thank you,
