In phonetics, what is a sound that is characterized by an open configuration of the vocal tract so that there is no build-up of air pressure above the glottis?
Glottis occasionally of and ); in some languages, this sound is a phoneme of its own. Skilled players of the Australian didgeridoo restrict their glottal opening in order to produce the full range of timbres available on the instrument. The vibration produced is an essential component of "voiced" consonants as well as vowels. If the vocal folds are drawn apart, air flows between them causing no vibration, as in the production of voiceless consonants. The glottis is also important in the valsalva maneuver. Glottis The glottis is the opening between the vocal folds (the rima glottidis). As the vocal folds vibrate,
Articulatory phonetics of the contact is. Articulatory phonetics The field of articulatory phonetics is a subfield of phonetics. In studying articulation, phoneticians explain how humans produce speech sounds via the interaction of different physiological structures. Generally, articulatory phonetics is concerned with the transformation of aerodynamic energy into acoustic energy. Aerodynamic energy refers to the airflow through the vocal tract. 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. The vocal tract
