Tesco is aiming to cut the cost of selling houses with a new telephone property service.
The system allows potential buyers to input a reference number from the board outside the property, before hearing an automated one-minute description of the house.
They will hear details such as the asking price and number of rooms. Tesco said property details held on the database will be blended with "keyword phrasing of a voice artist to provide a natural sounding, one minute description".
The telephone system was built using the ContactWorld telephony platform from NewVoiceMedia.
The company said the platform will give "individual caller treatment", meaning each caller is processed in a special way according to spending patterns or previous call history.
Tesco has used IT in several ambitious projects. It is in the process of standardising its IT process to enable further global expansion, and has installed heat sensors in its supermarkets to identify bottlenecks of consumers. It is also one of the UK's biggest online retailers.
NewVoiceMedia CEO Jonathan Grant said, "We are confident that ContactWorld will help Tesco to revolutionise the property market."
