Justice Secretary Chris Grayling said plans to pre-record testimony in criminal trials were designed to allow vulnerable victims to give evidence in "as easy and unchallenging a way as possible".
"The aim is to really take the victim out of the cauldron of the courtroom," he told the BBC Radio 4 Today programme.
"I hope that it will give victims greater confidence to talk about what's happened to them."
