Secondary articulation refers to co-articulated consonants 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 obscuring it. For example, the voiceless labialized velar plosive 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 articulatedlabial-velar consonant , which has two equal stop articulations at the velum and lips.
