If you're reading this article, it's likely that you have already made the decision to hire a professional voice actor or actress for your marketing project - congratulations!  A voice over professional can add a lot to just about any project. After this decision, however, comes perhaps the most difficult yet essential part of the process: interviewing. Those who have not done extensive work involving voice over may be wondering what exactly it is that sets truly great voice actors and actresses apart from the rest of the pack.

1.He or she has  a believable voice.  Though there is certainly a place for exaggerated narration in the style of an announcer or newscaster, you're generally going to want an actor or actress who can perform naturally in a wide range of vocal styles.

2.A good sense of pitch.  Beautiful voices don't happen by accident - they are cultivated with much practice. Many of the best voice actors are also accomplished singers, and this is because both disciplines require a studied grasp of pitch and tone.

3.He or she is willing to provide you with high quality examples of his or her work. When interviewing voice over talent, it's essential that you obtain a demo tape from each of your prospects.  In addition to granting you insight into the quality of a candidate's work, this will help you keep your prospects straight after you're done interviewing.

4.Versatility.  This is fairly self-explanatory; a truly skilled voice over professional will have the skill and talent necessary to perform well in a wide variety of dissimilar projects.  Whether authoritatively reading off facts and figures, or attempting to make listeners laugh, a true professional will shine.

5.A good sense of tempo.  Another 'musical' element of voice over work is that of tempo, or pacing; you should look for a voice actor or actress whose speech flows naturally, and who has an intuitive grasp of the the rhythm with which he or she must speak in order to get your message across.

6.The voice over artist has solid references.  Take the time to review references or testimonials to determine if you're working with an amateur or professional. Voice over artists who have a history of quality projects, working with a diverse set of clients, and providing consistency with their work are strong candidates for your project.

7.He or she exhibits enthusiasm and vocal stamina.  At times, recording a voice is no picnic; lines will likely need to be repeated over and over to get the exact right take.  Be sure to pick a candidate that will maintain a good attitude and a strong voice under these conditions.

Interviewing potential voice talent may, at times, feel tedious, but in reality it is a key factor in the success of your project.  If you can find a voice actor or actress with all of the aforementioned traits during the interview process, you will save yourself a lot of time and trouble down the road.
