Will Cheryl Cole's Newcastle accent work in America

Marina Tyndall, a voice coach specialising in accent and dialect, rejects the notion that some vocal styles are intrinsically clearer to American listeners than others.

Cole, she says, could quite easily accommodate her accent to unfamiliar Stateside ears without abandoning it. Techniques she suggests include "chunking" words into shorter phrases with brief pauses, allowing listeners time to catch up - and using facial expressions and pitch changes to signpost key words.
