Owners complained that their voice-activated devices set off on an inadvertent shopping spree after a California news program triggered the systems to make erroneous purchases, according a local report. A morning show on San Diego’s CW6 News station had been covering a segment about a six-year-old girl in Texas who ordered to her home a dollhouse and four pounds of cookies through her parents’ gadget.

Echo devices, powered by Amazon (AMZN) Alexa, the tech giant’s artificially intelligent voice assistant, reportedly woke when they heard the name “Alexa” spoken on household television sets. Jim Patton, an anchor on the show, had remarked, “I love that little girl saying ‘Alexa ordered me a dollhouse.'”

The comment proved mischievous. A number of Amazon Echos registered the statement as a voice command, and placed orders for dollhouses of their own, the station said.

“A handful” of people said that their devices accidentally tried to buy the toys, reported the Verge, which spoke to the station, although the total figure is not known. Patton told the tech blog that he didn’t think any devices actually completed their purchases.

The misfires are attributable to Amazon’s decision to enable voice purchasing by default on Echo devices, even though they do not distinguish between different people. The setting is an obvious choice for Amazon, which makes money on e-commerce sales, but the added convenience comes at a cost of being more prone to error.

The incident highlights privacy and security concerns surrounding a new class of technologies that also includes Google (GOOG) Home, another device featuring a voice-activated assistant. Meanwhile, cops investigating an unrelated, possible murder in Arkansas recently subpoenaed Amazon, asking the company to hand over voice records potentially captured on an Echo device.
