The pharynx (plural: pharynges) is the part of the throat that is behind the mouth and nasal cavity and above the oesophagus and the larynx, or the tubes going down to the stomach and the lungs.
Vocal tract
The vocal tract is the cavity in human beings and in animals where sound that is produced at the sound source (larynx in mammals; syrinx in birds) is filtered.
Vocal folds
The vocal folds, also known commonly as vocal cords or voice reeds, are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx.
Larynx
The larynx /ˈlærɪŋks/ (plural larynges; from the Greek λάρυγξ lárynx), commonly called the voice box, is an organ in the neck of tetrapods involved in breathing, sound production, and protecting the trachea against food aspiration.
Laryngitis
Laryngitis is an inflammation of the larynx.
Glottis
The glottis is defined as the opening between the vocal folds (the rima glottidis).
Arytenoid cartilage
The arytenoid (/ærᵻˈtiːnɔɪd/) cartilages are a pair of small three-sided pyramids which form part of the larynx, to which the vocal folds (vocal cords) are attached.
Bogart–Bacall syndrome
Bogart–Bacall syndrome (BBS) is a voice disorder that is caused by abuse or overuse of the vocal cords.
Reverse speech
Reverse speech is a pseudoscience first advocated by David John Oates which gained publicity when it was mentioned on Art Bell's nightly Coast to Coast AM radio talk show.
Cluttering
Cluttering (also called tachyphemia or tachyphrasia) is a speech and communication disorder characterized by a rapid rate of speech, erratic rhythm, and poor syntax or grammar, making speech difficult to understand.
Alaryngeal speech
Alaryngeal speech is speech made using sources other than the glottis in the larynx to create voiced sound.
Speech transmission index
Speech Transmission Index (STI) is a measure of speech transmission quality.
Vocal pedagogy
Vocal pedagogy is the study of the art and science of voice instruction.
Vocal process
In the human larynx, the vocal process is the anterior angle of the base of the arytenoid cartilage, as it projects horizontally forward and gives attachment to the vocal ligament.
Hypernasal speech
Hypernasal speech (also hyperrhinolalia or open nasality; medically known as Rhinolalia aperta from Latin rhinolalia: "nasal speech" and aperta: "open") is a disorder that causes abnormal resonance in a human's voice due to increased airflow through the nose during speech.
