Technical investor John Borthwick said that smart speakers have multiple "problematic" layers, claiming the devices were being used for surveillance.
"I would say that there are two or three layers of problematic layers in these new smart speakers that are currently on the market," said Borthwick in an interview with Yahoo Finance published Sunday.
"From a consumer's point of view, the first thing is that these devices are used for what – it's hard to call it other than surveillance".
Borthwick told Yahoo There must be more regulatory levels that give consumers control over the data.
"I personally believe that as a user and as someone who likes technology that wants to use technology, you should have far more rights. Your data usage is higher than it is today," he said.
Bloomberg reported in April that Amazon employees hear what consumers demand from their Alexa devices.
Similar products are offered by Google and Apple ̵
Bloomberg issued another report in which Facebook listened to the voice commands of users created through the Messenger app.
Companies claimed to use the information to improve e-products.
Google has stopped the process and Apple has announced that it will automatically stop the detection of language patterns according to Yahoo.
According to Yahoo, Amazon has since allowed users to opt-out of sharing their voice commands with employees.
