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.

the tongue form the harmonics.
• Changing the muscular tension in the vocal
chords changes the pitch of the singing or
speaking voice.

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.
