One of the basic principles of voice over training is proper pronunciation. Because pronuciation can vary by area it is vital to verify the copy before you begin recording. Some producers will furnish a guide with the intended way to pronounce certain common or unusual words, and first and last names that may be suspect. If you are not supplied these guidelines along with your script, then it is your duty as voice over talent to go over and affirm the script. A quick read through will clear up any possible issues so that the job can be completed in as few takes as possible and so that you can develop a reputation of professionalism and dependability.
