ABSTRACT
This chapter explains about the sounds with more than one articulation. Consonant sounds have a simple articulation that is one part only of the organs of speech is concerned in making them. The action of the vocal cords in producing voice is neglected here. There are some consonants, however, in which more than one part of the articulating organs is concerned: these are said to have a double articulation. In some African languages there are a number of sounds with more than one articulation, some of them involving very complicated combinations of articulations. Further combinations will be considered under the headings of Labialization, Palatalization, and Velarization. Several sounds must be considered in more than one category, since it is often found that labialization is combined with palatalization and with velarization. Labialization is the adding of a rounding of the lips to sounds articulated in another part of the mouth. Also Labialization can be added to a large number of consonants.
