Kirsty Young's castaway is the renowned voice coach Patsy Rodenburg.

Her work at the National Theatre and the RSC has spanned decades and her students include Dame Judi Dench, Sir Ian McKellen, Dame Maggie Smith and Daniel Day Lewis. But her work takes her away from the stage too - she has coached politicians and helped offenders in prison. She says: "I did some work on Hamlet in a top security prison and the guy playing Claudius was a murderer and he spoke, 'Oh my offence is rank, it smells to heaven', and he just broke."
