For how many topics and spoken words does this not happen for? You probably can't count them. I don't think this happens because I don't think it's technically feasible. The hotword detection stuff that is always on ("hey siri", "ok google") is incredibly limited in vocabulary. Maybe one day that will change, maybe it's even possible now, but people have been telling stories like yours since well before I know for sure it was technically infeasible to do it.
