The human voice frequency is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. (Other sound production mechanisms produced from the same general area of the body involve the production of unvoiced consonants , clicks , whistling and whispering .)
Acoustic energy is variation in the air pressure that can be represented as sound waves, which are then perceived by the human auditory system as sound. [a] Respiratory sounds can be produced by expelling air from the lungs. However, to vary the sound quality in a way useful for speaking, two speech organs normally move towards each other to ...
Speech production is the process by which thoughts are translated into speech. This includes the selection of words , the organization of relevant grammatical forms, and then the articulation of the resulting sounds by the motor system using the vocal apparatus .
Human vocal cords are paired structures located in the larynx, just above the trachea, which vibrate and are brought in contact during phonation.

In contrast, a pop artist could include notes that could be heard with the aid of a microphone. Another factor to consider is the use of different forms of vocal production. The human voice is capable of producing sounds using different physiological processes within the larynx. These different forms of voice production are known as vocal ...

The communicative modality of a language describes the method by which a language produces and perceives languages. Languages with oral-aural modalities such as English produce speech orally and perceive ...
