Smart speakers are a popular tech accessory, with many of them likely gifted over Christmas - but experts have warned they may be recording what we say.
One brand that is credited with pioneering the technology is Amazon Alexa. The nifty device can assist with daily tasks, issue news and weather updates and play music with a simple voice command.
While Alexa is a great time saver, tech specialists have given their opinions on the technology and warned users to keep it out of private areas, the Liverpool Echo reports.
When the digital assistant gained popularity, Dr Hannah Fry, mathematician and expert on tech company algorithms advised that they should be left downstairs rather than bedrooms or bathrooms as she said the technology can record conversations.
The associate professor at University College London explained: "I think there are some spaces in your home, like the bedroom and bathroom, which should remain completely private.
"This technology is activated by a trigger word but it keeps recording for a short period afterwards. People accept that, but we should all spend more time thinking about what it means for us."
After Dr Fry asked tech firms to provide the data they had collected on her, she said she found recordings of conversations taken from within her home.
She added that 'very senior' people in the tech industry won't even take a smartphone into their bedroom and buyers should be very wary of low price technology with microphones linked to the internet.
Amazon previously admitted staff listen to customers' conversations through Alexa, stating the recordings were used to help improve the Echo device’s understanding of human speech.
A report by news site Bloomberg suggested many users are unaware humans are listening in, with staff each able to review up to 1,000 audio clips a day.
Teams had also shared recordings they found funny in internal chat rooms. Experts on Forbes tech panel also shared tips about voice-activated tech that users should be aware of.
Carolyn Jenkins, from EPSoft Technologies said: "Voice-activated tech is a tool, and like any tool, it can be used well or badly. Start by understanding the privacy and security settings available in the voice tech you are using, as well as the data retention policies of the company supplying the tech.
"Presume everything you say is being listened to and recorded, and adjust the settings you can from there until you are comfortable."
Brad Thomas, from Prophecy International said: "These technologies are great time-savers and make life easier, but they also make it easy to inadvertently share private information without thinking. These devices are always on, collecting data about you and your habits to better provide services—but there is no filter, and they simply collect it all.
"This makes it too easy to share private data with big tech that you did not intend to share."
