Clever attack! Then the phone AI voice command system must start to recognize that the speakers voice is the original speaker via user finger printing. Then the attacker will counter attack with another new system that emulates the original speakers voice and speech rate via deep learning. You will then as a counter measure have to press a hardware button to use voice commands. Seems like microphone proximity sensing and frequency filtering are easy first starts as counter measure as already mentioned in this thread.
