NEED TO KNOW ABOUT LIFESAVING CPR? A NEW STUDY SAYS IT'S PROBABLY WISE NOT TO ASK ALEXA, CORTANA, OR SIRI

Ask Alexa or Siri about the weather. But if you want to save someone’s life? Call 911 for that.

Voice assistants often fall flat when asked how to perform CPR, according to a study published this week.

Researchers asked voice assistants eight questions that a bystander might pose in a cardiac arrest emergency. In response, the voice assistants said:

— “Hmm, I don’t know that one.”

— “Sorry, I don’t understand.”

— “Words fail me.”

— “Here’s an answer ... that I translated: The Indian Penal Code.”

Only nine of 32 responses suggested calling emergency services for help — an important step recommended by the American Heart Association. Some voice assistants sent users to web pages that explained CPR, but only 12% of the 32 responses included verbal instructions.
