“I have worked with Carter on a number of occasions to help me with an American dialect. He is a fantastic teacher who I would happily recommend.”

— Jodie Whitaker (Doctor Who, Broadchurch)

“Carter - What a brilliant dialect coach! Precision, detail, encouragement, and great humour. He’s just superb at what he does. Highly recommended.”

— Matthew Macfadyen (Frost/Nixon, HBO's Succession)

“I worked on my General American accent with Carter for a film in which I was to be surrounded by real Americans. I was a little nervous and found him to be exactly what I want from a dialect coach and extremely useful. He is enormously specific, knowledgeable and encouraging. He broke down the sounds and placement in a fantastically digestible way and gave me detailed documents to help me keep developing whilst away. I would highly recommend him and intend to work with him from now on.”

— Alex Hassell (RSC Henry V, Suburbicon, Anonymus)

“Carter is my go-to for all accents American. His precision and humour make learning new accents a pleasure.”

— Olivia Grant (Indian Summers, Genesis)
