The horizontal dimension of the vowel diagram includes tongue advancement and identifies how far forward the tongue is located in the oral cavity during production. Vowels are also categorized by the tenseness or laxness of the tongue. The schwa [ə] is in the center of the chart and is frequently referred to as the neutral vowel. Here, the ...
Midsagittal view of the human mouth. Transducer (sensor) coils are typically placed on the tongue and lips. Electromagnetic articulography (EMA) is a method of measuring the position of parts of the mouth. EMA uses sensor coils placed on the tongue and other parts of the mouth to measure their position and movement over time during speech and ...
The tongue body creates a velaric airstream by changing the pressure within the oral cavity: the tongue body changes the mouth subcavity. Click consonants use the velaric airstream mechanism. Pistons are controlled by various muscles. Valves regulate airflow between cavities. Airflow occurs when an air valve is open and there is a pressure ...
The difference between the Romance languages and English is not so much where the tongue contacts the roof of the mouth but the part of the tongue that makes contact. In English, it is the tip of the tongue (such sounds are termed apical), but in the Romance languages, it is the flat of the tongue just above the tip (such sounds are called ...
Visible Speech is a system of phonetic symbols developed by British linguist Alexander Melville Bell in 1867 to represent the position of the speech organs in articulating sounds. Bell was known internationally as a teacher of speech and proper elocution and an author of books on the subject.
Alveolar consonants may be articulated with the tip of the tongue (the apical consonants), as in English, or with the flat of the tongue just above the tip (the "blade" of the tongue; called laminal consonants), as in French and Spanish. The International Phonetic Alphabet (IPA) does not
In linguistics, specifically articulatory phonetics, tongue shape describes the shape that the tongue assumes when it makes a sound. Because the sibilant sounds have such a high perceptual prominence, tongue shape is particularly important; small changes in tongue shape are easily audible and can be used to produce different speech sounds, even within a given language.
Consonants are pronounced in the vocal tract, usually in the mouth, and the location of this constriction affects the resulting sound. Because of the close connection between the position of the tongue and the resulting sound, the place of articulation is an important concept in many subdisciplines of phonetics.
