Normal velar consonants are dorso-velar: The dorsum (body) of the tongue rises to contact the velum (soft palate) of the roof of the mouth. In disordered speech there are also velo-dorsal stops, with the opposite articulation: The velum lowers to contact the tongue, which remains static.
[2] [30] There are two types of prosthesis: the speech bulb and the palatal lift prosthesis. [2] The speech bulb is an acrylic body that can be placed in the velopharyngeal port and can achieve obstruction. The palatal lift prosthesis is comparable with the speech bulb, but with a metal skeleton attached to the acrylic body. [30]
The term 'velopharyngeal' indicates "articulation between the upper surface of the velum and the back wall of the naso-pharynx." [ 4 ] The base symbol for a velopharyngeal fricative in the extensions to the International Phonetic Alphabet for disordered speech is ʩ , and secondary articulation is indicated with a double tilde, ͌ .
A speech sound made with the middle part of the tongue (dorsum) touching the soft palate is known as a velar consonant. It is possible for the soft palate to retract and elevate during speech to separate the oral cavity (mouth) from the nasal cavity in order to produce the oral speech sounds.
The three types of ingressive sounds are lingual ingressive or velaric ingressive (from the tongue and the velum), glottalic ingressive (from the glottis), and pulmonic ingressive (from the lungs). The opposite of an ingressive sound is an egressive sound, by which the air stream is created by pushing air out through the mouth or nose. The ...
An example of a doubly articulated consonant is the voiceless labial–velar plosive [k͡p], which is a [k] and a [p] pronounced simultaneously. On the other hand, the voiceless labialized velar plosive [kʷ] has only a single stop articulation, velar ([k]), with a simultaneous approximant-like rounding of the lips.
A common example of a velarized consonant is the velarized alveolar lateral approximant (or "dark L"). In some accents of English, such as Received Pronunciation and arguably General American English, the phoneme /l/ has "dark" and "light" allophones: the "dark", velarized allophone [ɫ] appears in syllable coda position (e.g. in full), while the "light", non-velarized allophone [l] appears in ...
They are frequently contrasted with velar or uvular consonants, though it is rare for a language to contrast all three simultaneously, with Jaqaru as a possible example of a three-way contrast. [26] Velar consonants are made using the tongue body against the velum. They are incredibly common cross-linguistically; almost all languages have a ...
