You must spend some time to find the perfect voiceover artist for your commercial. The search for the best voiceover artist includes listening to voiceover demo tapes sent by each applicant. You can initially gauge the style and suitability of an applicant to your project by listening to demo tapes.

Asking applicants to send in demo tapes can be a better alternative to asking artists to schedule a voice over test in your office. Interviews can put some pressure on artists while a demo tape will give them a chance to do a natural and unstrained performance. Then again, you need to have a set of criteria in listening to voiceover demos. Below are five important criteria you need to evaluate:

1. Pace. Pay attention to the speed of the actor's delivery. A good voiceover artist is someone who can adjust his pace easily to emphasize different ideas. Rodney Saulsberry, author of "You Can Bank On Your Voice", states that the speed of delivery has an important effect on any voice over piece. Good artists understand that a very slow delivery and an extremely fast delivery are a pain to listen to and they should know how to pace their voice throughout a piece.

2. Arouses interest. You want voiceover talents that can easily grab your attention right at the beginning of a set. Along with a talent's tone, good voiceover talents can stress specific words and emphasize important phrases to stir interest in a piece. Prioritize tapes that start out strong and are able to sustain that initial interest through the end.

3. Dialect and accents. Many talented voiceover artists have the ability to imitate certain accents and dialects. Listen for examples of different accents and styles; these indicate that the artist is flexible and skilled in changing tones and can play different characters with ease.

4. Rhythm and beat. Voice over monologues and conversations must be delivered using the appropriate rhythm in order to be successful. A voiceover with the right rhythm will have greater recall and higher brand identification among listeners. Listen for the rhythm or flow as an artist delivers each line.

5. Wit. Comedy is an integral part of many successful voiceover scripts. Listen if an applicant displays wit through a cheerful tone and jokes. Assess if the artist delivered his jokes in such a way as it made you smile or made you feel uncomfortable.

Use voice over demo tapes to help you judge every candidate to pick out the best talent that would fit your voice over project. Listen to each demo tape with the above qualities in mind so that you will have an objective standard to base your decision on. Good voiceover artists possess these qualities and are able to easily exhibit them in a demo tape.
