Talking improperly for long periods of time causes vocal loading, which is stress inflicted on the speech organs. When vocal injury is done, often an ENT specialist may be able to help, but the best treatment is the prevention of injuries through good vocal production. [23] Voice therapy is generally delivered by a speech-language pathologist.
The production of speech is a highly complex motor task that involves approximately 100 orofacial, laryngeal, pharyngeal, and respiratory muscles. [2] [3] Precise and expeditious timing of these muscles is essential for the production of temporally complex speech sounds, which are characterized by transitions as short as 10 ms between frequency bands [4] and an average speaking rate of ...
Its potential form is air pressure; its kinetic form is the actual dynamic airflow. 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 ...
See buccal speech. [1] after a laryngectomy, the esophagus may be used (notated {Œ} for simple esophageal speech, {Ю} for tracheo-esophageal speech in VoQS, and notated {И} for electrolaryngeal speech). See esophageal speech. [2] the pharynx, and replacing the glottis using the tongue and the upper alveolus, the palate, or the pharyngeal wall.
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 .
Trills involve the vibration of one of the speech organs. Since trilling is a separate parameter from stricture, the two may be combined. Increasing the stricture of a typical trill results in a trilled fricative. Trilled affricates are also known. Nasal airflow may be added as an independent parameter to any speech sound.

Speech is the subject of study for linguistics, cognitive science, communication studies, psychology, computer science, speech pathology, otolaryngology, and acoustics. Speech compares with written language, [1] which may differ in its vocabulary, syntax, and phonetics from the spoken language, a situation called diglossia.
