Central Consonant
A central consonant, also known as a median consonant, is a consonant sound that is produced when air flows across the center of the mouth over the tongue. The class contrasts with lateral consonants, in which air flows over the sides of the tongue rather than down its center. Examples of central consonants are the voiced alveolar fricative (the "z" in the English word "zoo") and the palatal approximant (the "y" in the English word "yes"). Others are the central fricatives , the central approximants , the trills , and the central flaps . The term is most relevant for approximants and fricatives (for which there are contrasting lateral and central consonants - e.g. versus and versus ). Stops that have "lateral release" can be written in the International Phonetic Alphabet using a superscript symbol, e.g. , or can be implied by a following lateral consonant, e.g. . The labial fricatives often—perhaps usually—have lateral airflow, as occlusion between the teeth and lips blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Palatogram
Palatography is a technique used to identify which parts of the mouth are used when making different sounds. This technique is often used by linguists doing field work on little-known natural languages. A record made through palatography is called a ''palatogram''. It involves painting a coloring agent, such as a dye or a mixture of charcoal and olive oil on the tongue or the palate, roof of a person's mouth and having that person pronounce a specific sound. A photograph is then made of the mouth roof and tongue in order to determine how the sound was articulated. The technique can also be performed electronically (electropalatography) using a tool called a pseudo-palate, which consists of a retainer (orthodontics), retainer-like plate lined with electrodes that is placed on the roof of the mouth while the speaker pronounces a sound.
