Amazon Alexa Plus bug makes some Echo speakers repeat “lalala”

A bug is causing some Amazon Echo smart speakers running Alexa Plus to repeat the sound “lalala” for minutes at a time. The speakers sometimes sing it, and the behavior has reportedly occurred during conversations with users.

When asked about the behavior, Alexa is apparently unaware of what it has been doing, according to The Verge, citing reports and videos shared by users. Reports have appeared repeatedly on Reddit over the last few weeks, including one posted three days before the source article. The issue has affected multiple types of Echo speaker.

Amazon told Android Authority that the bug affects “a small number of Alexa Plus” users and that a fix is in the works. Android Authority also uploaded a video of the behavior to YouTube.
