The cornerstone of any successful audition is a good description of the assignment and your expectations. The talent needs to understand the purpose of the recording, the target group and the type of expression and voice you expect. This ensures highly relevant offers.
When selecting your candidates, you should pay attention to a professional implementation, recognizable by precise articulation, lively, authentic expression (according to your specifications) and a technically flawless recording (no hiss, no background noises, no room ambiance, etc.)
Tip: The price should not – within reason, of course – play a major role in your considerations. Shopping the bottom shelf because of a 20 percent saving certainly does not justify the risk of your project being totally rejected by your target group because of a voice talent that did fit the job.
