It turns out that in rare circumstances, Alexa can mistakenly hear the phrase “Alexa, laugh” even when that’s not what was said. Alexa then interprets the phrase as a command and laughs.

Amazon has changed the phrase necessary to make Alexa laugh to, “Alexa, can you laugh” which should be less likely to generate false positives.

In addition, Alexa will no longer respond to that question with simple laughter but instead will say, “Sure, I can laugh” followed by laughter.
