We have all visited the doctor's office at one point in our lives. Doctor voices are usually reassuring because a person who is ill needs positive energy as they fight to get better. Doctors are the professionals we turn to when we don't know what is happening to our bodies.
A doctor's voice has the potential to bring your script back to life; that is if you've been working on a series of audio projects. It can also be used independently to pass a specific message. Your voice actor should be conversant with acting a doctor's role. Make sure you establish the kind of doctor you want to cast. It could be one who does everything by the book or a reckless one who gets things wrong sometimes.
A doctor's voice can be used to target anyone because everyone needs a doctor in their life. However, you must tailor the message to target specific segments. After all, doctor's appointments are not the one-fits-all kind. Each person is unique and requires special care from doctors. Case in point, you cannot target cancer patients with audio that's talking about asthma or pregnancy.
A doctor's voice should be laid back, inquisitive, introspective, and analytical. It should also be characterized by intellect and authority. The medical field is a technical one, so you can feel free to use terminologies as well.
