Stop the voice synthesis with this instruction.

This function stops immediately the actual spoken speechUtterance object and cancels all the pending objects to speak. Under the hood, artyom uses speechSynthesis.cancel.

artyom.say("Hello, this is a very very long string.\n\
           I'm getting tired. Better someone silence me otherwise\n\
           i will never stop talking . No one? please someone stops me. You will never hear this.");

  * Stop talking after 2 seconds.
