Human vocal tract Articulation visualized by real-time MRI. In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators (speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is stricture, that is
Consonants are speech sounds that are articulated with a complete or partial closure of the vocal tract. They are generally produced by the modification of an airstream exhaled from the lungs. The respiratory organs used to create and modify airflow are divided into three regions: the vocal tract (supralaryngeal), the larynx , and the ...
Consonants that have the same place of articulation, such as the alveolar sounds /n, t, d, s, z, l/ in English, are said to be homorganic. Similarly, labial /p, b, m/ and velar /k, ɡ, ŋ/ are homorganic. A homorganic nasal rule, an instance of assimilation, operates in many languages, where a nasal consonant must be homorganic with a following ...
The manner of articulation is how air escapes from the vocal tract when the consonant or approximant (vowel-like) sound is made. Manners include stops, fricatives, and nasals. The place of articulation is where in the vocal tract the obstruction of
Manner features: The features that specify the manner of articulation. [+/− continuant ] [ 8 ] This feature describes the passage of air through the vocal tract. [+cont] segments are produced without any significant obstruction in the tract, allowing air to pass through in a continuous stream.
As a rule, a click is replaced by a consonant with close to the manner of articulation of the click and the place of articulation of the forward release: alveolar click releases (the [ǃ] family) tend to mutate into a velar stop or affricate, such as [k], [ɡ], [ŋ], [k͡x]; palatal clicks ([ǂ] etc.) tend to mutate into a palatal stop such as ...
Two or more consonant sounds may appear sequentially linked or clustered as either identical consonants or homorganic consonants that differ slightly in the manner of articulation, as when the first consonant is a fricative and the second is a stop.
Speech sounds can be described in a number of ways. Most commonly speech sounds are referred to by the mouth movements needed to produce them. Consonants and vowels are two gross categories that phoneticians define by the movements in a speech sound. More fine-grained descriptors are parameters such as place of articulation.
