Jean Maurice Eugène Clément Cocteau (] ; 5 July 1889 – 11 October 1963) was a French writer, designer, playwright, artist and filmmaker.
 Cocteau is best known for his novel "Les Enfants Terribles" (1929), and the films "The Blood of a Poet" (1930), "Les Parents Terribles" (1948), "Beauty and the Beast" (1946) and "Orpheus" (1949).
 His circle of associates, friends and lovers included Kenneth Anger, Pablo Picasso, Gertrude Stein, Jean Hugo, Jean Marais, Henri Bernstein, Yul Brynner, Marlene Dietrich, Coco Chanel, Erik Satie, Albert Gleizes, Igor Stravinsky, Marie Laurencin, María Félix, Édith Piaf, Panama Al Brown, Colette, Jean Genet, and Raymond Radiguet.
The human voice consists of sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming, etc.
 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.)
 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.
The Vox humana (Latin for "human voice;" also "voz humana" in Spanish and Portuguese, "voix humaine" in French and "voce umana" in Italian, although "voce umana" is also a term for a "celeste" stop, q.v.) is a short-resonator reed stop on the pipe organ, so named because of its supposed resemblance to the human voice.
 As a rule, the stop is used with a tremulant, which undulates the wind supply, causing a vibrato effect.
 The vox humana is intended to evoke the impression of a singing choir or soloist, though the success of this intent depends as much upon the acoustics of the room in which the organ speaks as it does the voicing of the pipes.
 It is almost invariably at 8′ pitch, though on theater organs it is not uncommon to encounter a chorus of vox humana stops at 8′ and 4′ pitch, with the addition of a 16′ acting as a pedal stop.
The Human Voice (French: "La Voix humaine" ) is a monodrama first staged at the Comédie-Française in 1930, written two years earlier by Jean Cocteau.
 It is set in Paris, where a still-quite-young woman is on the phone with her lover of the last five years.
 He is to marry another woman the next day, which causes her to despair.
 The monologue triggers the woman's crippling depression.
A vocoder ( , a portmanteau of "voice encoder") is a category of voice codec that analyzes and synthesizes the human voice signal for audio data compression, multiplexing, voice encryption, voice transformation, etc.
Voice therapy, also known as speech therapy or voice training, encompasses a myriad of techniques employed in the management of voice disorders or the improvement of the human voice for the purpose of singing or acting, or for achieving a specific gender intonation, as in the case of transgender people.
 It is provided by speech-language pathologists or voice coaches.
The Bell Telephone Laboratory's Voder (from "Voice Operating Demonstrator") was the first attempt to electronically synthesize human speech by breaking it down into its acoustic components.
 It was invented by Homer Dudley in 1937–1938 and developed on his earlier work on the vocoder.
 The quality of the speech was limited; however, it demonstrated the synthesis of the human voice, which became one component of the vocoder used in voice communications for security and to save bandwidth.
Voice therapy or voice training refers to any non-surgical technique used to improve or modify the human voice.
 Because voice is a "gender cue", trans people may frequently undertake voice therapy as a part of gender transition in order to make their voices sound more like what is typical of their gender, and therefore increase their readability as that gender in society.
A voice type is a particular human singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points ("passaggio"), such as breaks and lifts within the voice.
 Other considerations are physical characteristics, speech level, scientific testing, and vocal register.
 A singer's voice type is identified by a process known as voice classification, by which the human voice is evaluated and thereby designated into a particular voice type.
 The discipline of voice classification developed within European classical music and is not generally applicable to other forms of singing.
 Voice classification is often used within opera to associate possible roles with potential voices.
 Several different voice classification systems are available to identify voice types, including the German "Fach" system and the choral music system among many others; no system is universally applied or accepted.
Voice stress analysis (VSA) and Computer Voice Stress Analysis (CVSA) are collectively a pseudoscientific technology that aims to infer deception from stress measured in the voice.
 The CVSA records the human voice using a microphone, and the technology is based on the tenet that the non-verbal, low-frequency content of the voice conveys information about the physiological and psychological state of the speaker.
 Typically utilized in investigative settings, the technology aims to differentiate between stressed and non-stressed outputs in response to stimuli (e.g., questions posed), with high stress seen as an indication of deception.
