The upcoming Spice Girls Reunion Tour will not feature live singing. The internationally renowned singing group will be using state-of-the-art sound technology instead of singing live.

The girls are planning on using pre-recorded songs as part of a hi-tech system used to “repair” the singer’s online voice. A computer digitally compares it to the perfect vocal sounds already recorded and instantly corrects any mistakes.

“As they sing, the computer program corrects the mistakes so that the sound comes out as the desired sound – so they appear to be able to sing really well live,” says a British insider.
