Alexa and Siri are making children rude.
Alexa makes kids rude
Scientists fear that the voice assistants are having a negative impact on children as they are not taught good manners or how to read body language.
Dr. Anmol Arora, from Cambridge University, said: "Interacting with the devices at a crucial stage in social and emotional development might have long-term consequences on empathy, compassion and critical thinking."
Writing in the journal Archives of Disease in Childhood, he said: "With digital devices there is no expectation that polite terms, such as please or thank you should be used.
"There is no need to consider the tone of voice and whether the command being issued may be interpreted as rude or obnoxious."
Dr. Arora's claims have been disputed by Professor Pete Etchells, a psychologist at Bath Spa University.
He said: "There is no evidence I am aware of to support the idea such devices have a negative impact on development."
