“This was my first foray into audio books. I had no idea how to make it work, but Kelvin took care of everything. That really made it easy for me. He’s also very good at handling feedback and took my direction extremely well. All in all, he worked very hard to make my vision a reality, and I’ll be forever grateful.”

— Dan Smith, author of Saving Ebenezer

“There were over 20 professional narrators that auditioned for my audiobook, AI Hacked 2: Reimagine the Future. Upon hearing the first few sentences of Kelvin Witherspoon-Sudron’s audition piece, which was an excerpt from my book, we knew that we found our perfect narrator. During the production phase, my family and I looked forward to every chapter that Kelvin submitted. Kelvin is a master narrator par excellence. He is very pleasant to work with and delivers top quality audiobook production.”

— Elzar Simon, author of AI Hacked 2: Re-imagining the future

“Kelvin is amazing, efficient and very talented. He narrated my story of the Butler & Heiress (Book 1 - To Serve) with perfect delivery, cadence and tone. He brought the characters to life and you could feel the humour, frustrations and emotions of each and every character throughout the story.”

— Lexy Timms, USA Today Bestselling Author.

“I had the immense pleasure of working with Kelvin Witherspoon-Sudron on the audio book production of my bestselling modern vampire novel, Kiss of Life. I found Kelvin easy to work with, responsive to any corrections I required but most of all his presentation of the book and his adaptation of the characters was exactly what I was looking for from a narrator. He was able to convey not just the English characters, but also a number of Romanian characters, realistically and his voice definitely added a lustre to my written words. I would definitely recommend him as a narrator to anyone seeking a professional and fastidious person to present their work.”

— Brian L Porter. Amazon bestselling author.

“I found working with Kelvin extremely stress-free. He gave me several choices for each character's voice and surprisingly, together we went on to flush deeper back stories. If I wanted him to re-record a scene so we could try a different approach it was never a problem and he turned around the additional cuts very quickly. Kelvin treated and respected my novel as if he had written it himself, you can't ask for more than that.”

— David Leigh, Author Vanguard, War Of The Worlds

"Kelvin is absolutely wonderful to work with. He gets the timing perfectly with my characters. Whether it's a funny moment or a serious one, he never misses the tone. I always catch myself genuinely enjoying every moment of listening to how he brings my characters to life. He is one of my absolute favorite narrators to work with, and he's always made the entire process so easy on me!"

The narrator did an amazing job himself. I enjoyed how he was able to depict each character rather well. however, he sounded very much like Jude Law. I look forward to hearing more from this narrator.
