Co-articulated consonant consonant such as is doubly or secondarily articulated. In some English dialects, for example, is a labialized velar that could be transcribed as , but the Japanese is closer to a true labial-velar, . It is common usage to restrict the letter to the former. The glottis controls phonation, and works simultaneously with many consonants. It is not normally considered an articulator, and an ejective such as , with simultaneous closure of the velum and glottis, is not normally considered to be a co-articulated consonant. Co-articulated consonant Co-articulated consonants or complex consonants are consonants produced with two simultaneous places of
Speech science of the flow will increase at the area of constriction and cause a decrease in pressure below once distributed. This negative pressure will pull the initially blow open folds back together again. The cycle repeats until the vocal folds are abducted to inhibit phonation or to take a breath. In a third process of speech production, articulation, mobile and immobile structures of the face (articulators) adjust the shape of the mouth, pharynx and nasal cavities (vocal tract) as the vocal fold vibration sound passes through producing varying resonant frequencies.
