African people refers to natives or inhabitants of Africa and to people of African descent.
Many etymological hypotheses that have been postulated for the ancient name "Africa":
The African continent is home to many different ethnic and racial groups, with wide-ranging phenotypical traits, both indigenous and foreign to the continent. Many of these populations have diverse origins, with differing cultural, linguistic and social traits and mores. Distinctions within Africa's geography, such as the varying climates across the continent, have also served to nurture diverse lifestyles among its various populations. The continent's inhabitants live amid deserts and jungles, as well as in modern cities across the continent.
Perhaps it is a function of the number of excavations actually performed in given areas, but it is at least suggestive that the five very earliest out of the twelve of earliest archaeological discoveries of Homo sapiens sapiens have been in Africa and the adjacent Arabian peninsula.
The human voice consists of sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming, etc. Its frequency ranges from about 60 to 7000 Hz. The human voice is specifically that part of human sound production in which the vocal folds (vocal cords) are the primary sound source. 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. The lung (the pump) must produce adequate airflow and air pressure to vibrate vocal folds (this air pressure is the fuel of the voice). The vocal folds (vocal cords) are a vibrating valve that chops up the airflow from the lungs into audible pulses that form the laryngeal sound source. The muscles of the larynx adjust the length and tension of the vocal folds to ‘fine tune’ pitch and tone. The articulators (the parts of the vocal tract above the larynx consisting of tongue, palate, cheek, lips, etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to strengthen it or weaken it as a sound source.
