Secondary articulation refers to co-articulated consonants (consonants produced simultaneously at two places of articulation) where the two articulations are not of the same manner. The approximant-like secondary articulation is weaker than the primary, and colors it rather than obscure it. For example, the voiceless labialized velar plosive [kʷ] has only a single stop articulation, velar [k], with a simultaneous [w]-like rounding of the lips, and is usually heard as a kind of [k]. This is in contrast to the doubly articulated labial-velar consonant [k͡p], which has two equal stop articulations at the velum and lips. Co-articulated consonants are consonants produced with two simultaneous places of articulation. ... In speech, consonants may have different places of articulation, generally with full or partial stoppage of the airstream. ... In speech there are different ways of producing a consonant. ... Approximants are speech sounds that could be regarded as intermediate between vowels and typical consonants. ... Labialisation is a secondary articulatory feature of phonemes in a language, most usually used to refer to consonants. ... A stop, plosive, or occlusive is a consonant sound produced by stopping the airflow in the vocal tract. ... Velars are consonants articulated with the back part of the tongue (the dorsum) against the soft palate (the back part of the roof of the mouth, known also as the velum). ... Doubly articulated consonants are consonants with two simultaneous primary places of articulation of the same manner (both plosive, or both nasal, etc. ... Labial-velar consonants are doubly articulated at the velum and the lips. ...

There are a number of secondary articulations. The most frequently encountered are labialization (such as [kʷ]), palatalization (such as the Russian "soft" consonant [tʲ]), velarization (such as the English "dark" el [lˠ]), and pharyngealization (such as the Arabic "emphatic" consonant [tˤ]). Labialisation is a secondary articulatory feature of phonemes in a language, most usually used to refer to consonants. ... Palatalization means pronouncing a sound nearer to the hard palate, making it more like a palatal consonant; this is towards the front of the mouth for a velar or uvular consonant, but towards the back of the mouth for a front (e. ... Note: This page contains phonetic information presented in the International Phonetic Alphabet (IPA) using Unicode. ... Velarization is a secondary articulation of consonants by which the back of the tongue is raised toward the velum during the articulation of the consonant. ... The English language is a West Germanic language that originates in England. ... The velarized alveolar lateral approximant (also called dark l) is a type of consonantal sound, used in some spoken languages. ...

Arabic (العربية al-arabiyyah, or less formally arabi) is the largest member of the Semitic branch of the Afro-Asiatic language family (classification: South Central Semitic) and is closely related to Hebrew and Aramaic. ... Emphatic consonant is a somewhat imprecise term commonly used in Semitic linguistics to describe pharyngealized or velarized, and ejective consonants, or consonants that historically had one of these properties. ...

Although the symbol for secondary articulation is a superscript written after the primary consonant, this is misleading. They are pronounced simultaneously. Since secondary articulation has a strong effect on surrounding vowels, it will often seem that it precedes the consonant, or both precedes and follows it. For this reason, the IPA symbols for labialization and palatalization were for a time placed directly under the consonant (as [k̫] and [ƫ]), and there is still an alternate symbol for velarization/pharyngealizaton that is superposed across the consonant (as in [ɫ] for dark el). In phonetics, a vowel is a sound in spoken language that is characterized by an open configuration of the vocal tract, in contrast to consonants, which are characterized by a constriction or closure at one or more points along the vocal tract. ...
