Voice problems may result from the presence of vocal fold nodules. [13] They are diagnosed based on the presence of perceptual features not explicable by other causes. [13] Such symptoms include: vocal fatigue, breathiness, loss of high pitch notes, lack of vocal control, or increased phonatory effort (i.e. increased effort to produce speech). [13]
The vocal folds, in combination with the articulators, are capable of producing highly intricate arrays of sound. [2] [3] [4] The tone of voice may be modulated to suggest emotions such as anger, surprise, fear, happiness or sadness. The human voice is used to express emotion, [5] and can also reveal the age and sex of the speaker.

The vocal cords are composed of twin infoldings of 3 distinct tissues: an outer layer of flat cells that do not produce keratin (squamous epithelium). Below this is the superficial layer of the lamina propria , a gel-like layer, which allows the vocal fold to vibrate and produce sound.
The Laryngeal node is an organizing node that dominates the features of the larynx, usually taken to be [voice], [constricted glottis], and [spread glottis]. It is common for these three features to pattern together in the phonology of the world's languages to the exclusion of every other feature, and in feature geometry, this follows from the ...

The histological structure of the vocal fold can be separated into 5 [2] or 6 [3] tissues, depending on the source, which can then be grouped into three sections as the cover, the transition, and the body. The cover is composed of the epithelium (mucosa), basal lamina (or basement membrane zone), and the superficial layer of the lamina propria.
