Motorola Droid Turbo :: Why Does Android Phone Make Calls Independently And Interrupts When It Hears Music

My phone called someone in the middle of the night while I was sleeping. It has made a few other calls during the day without a requests from me. In addition if it hears music it starts sending a 3 bell ring and on screen asks if I will not speak more clearly. At times it talks and says "Speak more clearly." The screen sometimes shows a cloud when interrupting and other times a mic. I think this may be due to a malfunctioning google assist. I think it thinks music is my voice. Sometimes I am taking pictures with it and it hears music causing it to change from the camera mode to ring 3 tones and say speak more clearly. The calling and interruptions are nuisances.
