Is Alexa laughing at you?

In the past few days, some users of Echo home speakers running Amazon's Alexa voice-based digital assistant have reported hearing strange laughing noises at random. Some people have said the laughter happened in response to unrelated commands, while others reported that it occurred unprompted.

It's not clear what is causing the bug, but Alexa is indeed programmed to laugh if specifically asked to do so. An Amazon representative confirmed the problem and said the Seattle-based company is working on a remedy.

"We're aware of this and working to fix it," Amazon said.
