This section describes the dorsal fricatives and the fricatives where the dorsal/lateral opposition is unimportant.
Among the fricatives below are ones described as hissers and hushers. The realization of a hisser requires a high degree of tension in the tongue: a groove is formed along the whole length of the tongue, in particular at the place of articulation where the air passes through a little round opening. The hushers are produced similarly, but with a shallower groove in the tongue, and a little opening more oval than round. The lips are often rounded or projected outwards during the realization of a husher (see figure 3.14 below).
