"We're aware of this and working to fix it", Amazon told The Verge when asked about the unprompted laughter.
Another person heard the giggle at night: "Lying in bed about to fall asleep when Alexa on my Amazon Echo Dot lets out a very loud and creepy laugh", he said. Others then tweeted about similar occurrences with their own Alexa devices.
The short laugh that users have recorded and posted on Twitter consists of three closely-spaced "ha-ha ha's".

Alexa's laugh isn't the only thing that's freaking out users.
"I thought a kid was laughing behind me", he said. Amazon's smart speakers can be programmed to respond to a few words: "Alexa" is the most common, but other options like "Echo" and "Amazon" are available as well.
"I live alone and have lights controlled by Amazon Echo", he began. Moreover, people are saying that the laugh they're hearing isn't in Alexa's usual voice, which makes the experience even creepier. But it hasn't stopped from trying to bring new features that will attract new users to its music streaming fold.
Amazon had no comment on what, exactly, the problem is, or when it might be fixed.
