Elderly people are to be looked after by voice-activated virtual assistants in a new cost-cutting move to avoid them having to move into care homes.

The Amazon Echo devices will be installed in properties across Norfolk to help with everyday tasks as well as in emergencies, such as accidents or falls.

The 'smart-flat' scheme is to try and keep people independent and is hoped to save Norfolk County Council up to £1.5m over the next three years.

Bill Borrett, chairman of the council's adult social care committee, said: "This is a very exciting development.

"Most people want to live in their own homes for as long as possible - and, increasingly, technology can make the difference.

"We are setting up a demonstration flat, so people can see for themselves.

"Whether it's smart speakers that can remind people about appointments, or sensors which provide peace of mind for people's relatives, it's something that the county council is keen to expand."

The council claims that 7,000 people already use smart devices and social workers are assessing a further 2,000 people a year to see if they could benefit from the scheme.

However council bosses insist it will not become a substitute for human contact but will provide additional support for vulnerable and elderly people.

A Norfolk County Council spokesman said: "Assistive technology must never be a substitute for human contact but it can provide additional reassurance and support, for older and vulnerable people and their relatives."

The Amazon Echo is a voice controlled speaker which has the ability to carry out tasks such as answering simple questions, order shopping and and turn on lights and thermostats.

It can also set reminders for medicine and send out alerts in event of an emergency
