I have just produced an audiobook of Alice in Wonderland, read by myself and 165 different professional voices.
The interesting thing has been to listen to the myriad of different styles that the readers employed. From wonderfully heightened characterisations to more laid back, measured, relaxed reads. The ones that I loved, were the ones that allowed me to lose myself in the story.
Let me know what style you had in mind for your next production and I will be happy to produce a custom demo or provide a quote.
