A woman in Portland said that her family's Amazon Echo recorded her conversations, then sent them to a random contact without any human direction.
The couple tells KIRO-TV that they had a private conversation.
The company also said that "As unlikely as this string of events is, we are evaluating options to make this case even less likely".
Amazon suggested that it is adding a fix for Alexa-powered devices following a report that the device started laughing for no reason, due to the software misunderstanding what it had heard. But from what the woman told KIRO, it seems she and her husband didn't hear those questions.

"My husband and I would joke and say I'd bet these devices are listening to what we're saying", Danielle said.
"I felt invaded", Danielle said.
Its retail giant's critics argue that by selling its "Rekognition" technology, which can identify, track and analyze people in real time, to USA law enforcement and local authorities, Amazon threatens civil freedoms.

Hollywood women applaud impending Harvey Weinstein charges
Weinstein was charged with rape and a criminal sex act as well as lower-level sex abuse and sexual misconduct charges. Police in California and London have also been building a case against Weinstein over the numerous allegations.
The affected couple has four Amazon Alexa devices in their home which they use for controlling electrical devices and appliances.
"Amazon takes privacy very seriously". She quickly set out to unplug every Amazon Alexa unit in the house. "We are taking steps to avoid this from happening in the future", said the statement to the news station.
"Unplug your Alexa devices right now - you're being hacked", she was told. The pair continued talking in the background and the Echo system interpreted part of the chat to identify a name in the couple's contact list.
She said she'd asked for a refund for all their Alexa devices - something the company has so far demurred from agreeing to. At which point, the background conversation was interpreted as a name in the customers contact list.
The group found that commands could be hidden in white noise, with the device switching on and going to websites without being asked by a human.
