Amazon said Wednesday is investigating reports of Echo home speakers emitting sounds of laughter without being prompted.
Alexa is programmed to laugh, but only if specifically asked to do so.
Amazon issued a statement to The Verge, saying it is working on a solution for the unexplained bug.
"We're aware of this and working to fix it," the company said.
Amazon didn't provide a window for when the fix will be implemented, but can push updates to Alexa automatically.
