VOICE Home About Everyone's voice is unique so it is difficult to define a normal voice. A normal voice is pleasant sounding and has age and sex apropriate pitch and loudness. Voice is produced when the vocal folds (vocal cords) come close together and air from the lungs sets them vibrating in a regular fashion. The vibration causes a series of pulses, which in turn cause the air column in the vocal tract to resonate and produce a voiced sound. When we are breathing, our vocal folds are open , and air passes by without vibrating them. Some sounds (i.e. s, sh, f) are produced without voice. When the vocal folds are brought together, air pushes against the small opening and makes them vibrate, producing voicing. All vowels and some consonants (i.e. z, v, g) are voiced. Say "aaaaahhhhh" and feel the vibration in your voice box. Say a long "ssssss": there should be no vibrations. Voice disorders are divided into 2 categories: organic and functional. Organic voice disorders stem from disease or pathology. They require medical intervention. Functional voice disorders result from abuse or misuse of the voice. They often can be managed by voice therapy.
