Amazon promises fix for creepy Alexa laugh

Amazon's Alexa has been letting out an unprompted, creepy cackle - startling users of the best-selling voice assistant. The laugh, described by some as "witch like" was reported to sometimes happen without the device being "woken" up. Others reported the laugh occurring when they asked Alexa to perform a different task, such as playing music. "We're aware of this and working to fix it," Amazon said. Voice assistants like Alexa are designed to respond or act only when prompted with a wake word, which in this case is "Alexa" or "Amazon".
