Traill's account of East ǃXoon leaves for voiceless series of clicks without equivalents with a voiced lead. The DoBeS account of West West ǃXoon, which uses voicing for morphological derivation to a greater extent than East ǃXoon does, has four additional series, written nꞰʼʼ, gꞰʼ, gꞰqʼ and nꞰhh in their practical orthography. The first three match the unpaired glottalized series of Traill, (= ), , . If Traill's series is the voiced equivalent of plain aspirated , rather than delayed aspirated, that would leave the DobeS nꞰhh series as voiced delayed aspiration.
