The human voice is produced by the vibration of the vocal cords in the larynx. The vibration of the vocal cords produces the basic note, while the lips, tongue, and other articulators form harmonics to produce distinct sounds. Male voices are categorized as bass, baritone, or tenor, while female voices are contralto, mezzo-soprano, or soprano. The shape of the mouth, size of the throat, and nasal cavity also determine voice quality. The human voice involves the lungs, vocal folds, and articulators working together to generate a wide variety of sounds that can express different emotions.

The human voice is specifically a part of
human sound production in which the vocal
folds (vocal cords) are the primary sound
source.
The vibration of the vocal chords in the laryx
produces its note.

4. • The accompanying vibration of the lips and
the tongue form the harmonics.
• Changing the muscular tension in the vocal
chords changes the pitch of the singing or
speaking voice.

6. Factors determining the
quality of voice
The shape of the mouth
the size of the throat
the nasal cavity

7. Generally speaking, the mechanism for
generating the human voice can be
subdivided into three parts;
• the lungs
• the vocal folds within the larynx,
• and the articulators.

8. • The vocal folds, in combination with the
articulators, are capable of producing
highly intricate arrays of sound.
• The tone of voice may be modulated to
suggest emotions such as anger, surprise,
or happiness. Singers use the human voice
as an instrument for creating music.
