Apple has been chastised for letting humans transcribe human voice records when people know they are talking to Siri (an AI servant).
Amazon has been chastised for letting humans transcribe human voice records when people know they are talking to Alexa (an AI servant).
Google has been chastised for letting humans transcribe human voice records when people know they are talking to OK Google (an AI servant).
