is happening in speech recognition has there been much success in in being able to create adversarial examples that fool the system yeah actually I guess the first work that I'm aware of is a paper called hidden voice commands that came out in 2016 I believe and they were able to show that they could make sounds that are not understandable by a human but are recognized as the target phrase that the attacker wants the phone to recognize it as since then things have gotten a little bit better on the attacker side when worse on the defender
