1. Primary oral stops are those speech sounds made with a pulmonic air stream and a complete closure of two articulators (as in the single articulations /p,t/) or four articulators (as in the double articulations /kp, gb/). The release of such sounds may be sudden (as in the stops /p,t/) or delayed (as in the affricates /pf, ts/) (Nartey 1979: 17).2. Cf. Nartey’s less restrictive claim (#799): If there is a voiced obstruent, then most likely its voiceless cognate is present as well.
