As a voice actor, your voice is your tool, your instrument, and your asset. It is the key to unlocking success in the voice over industry. However, do you really understand how your voice works?
In this blog post, we’ll delve deeper into the mechanics of the voice, exploring the anatomy and physiology of the vocal mechanism, and how voice actors can make the most of their voice by understanding how it works.
The Anatomy of the Voice
The vocal mechanism is a complex system that includes the lungs, larynx, vocal cords, and articulators (tongue, lips, jaw, and palate). To produce sound, air is expelled from the lungs and forced through the larynx, where it causes the vocal cords to vibrate. This vibration creates sound, which is then shaped into speech by the articulators. (you probably already knew that. heehee!)
Here are the four main parts of the vocal mechanism:
Lungs: The lungs are responsible for producing the air needed for speech. The diaphragm, a dome-shaped muscle located at the bottom of the lungs, contracts and relaxes to control the flow of air.
Larynx: The larynx, also known as the voice box, is a structure in the throat that contains the vocal cords. The vocal cords are two elastic bands that can be stretched or relaxed to change the pitch of the voice.
Vocal cords: The vocal cords are two muscles that are covered by a mucous membrane. When air from the lungs passes through the vocal cords, they vibrate, creating sound.
Articulators: The articulators are the parts of the mouth and throat that shape the sound produced by the vocal cords into speech. These include the tongue, lips, jaw, and palate.
Physiology of the Voice
The voice is produced by the vibration of the vocal cords. The vibration rate, or frequency, of the vocal cords determines the pitch of the voice. The faster the vibration, the higher the pitch.
When you speak, your brain sends signals to the muscles of the vocal mechanism, causing them to contract and relax in a coordinated way. This creates the air pressure needed to vibrate the vocal cords and produce sound.
The sound produced by the vocal cords is then shaped into speech by the articulators. By changing the position of the tongue, lips, and jaw, different sounds can be produced.
Taking Care of Your Voice (the most important part!)
As a voice actor, it’s important to take care of your voice to ensure it is in top condition. Here are some tips to help you maintain a healthy voice:
Stay hydrated: Drink plenty of water to keep your vocal cords hydrated.
Avoid vocal strain: Avoid shouting or speaking loudly for extended periods of time unless you understand proper technique.
Warm up your voice: Before a recording session or performance, warm up your voice with vocal exercises.
Rest your voice: Take breaks between recording sessions and avoid speaking unnecessarily.
Avoid irritants: Stay away from irritants such as smoke and dry air, which can damage your vocal cords.
Maintain good overall health: A healthy lifestyle, including a balanced diet and regular exercise, can help maintain a healthy voice.
Making the Most of Your Voice
Understanding how your voice works can help you make the most of it as a voice actor. Here are some tips to help you maximize your voice potential:
Practice vocal exercises: Vocal exercises can help you develop your vocal range and control.
Experiment with your voice: Try different pitches, tones, and inflections to discover your voice’s full potential.

Work with a coach: A voice coach can help you improve your vocal technique and develop your skills as a voice actor.
