The expectation, from the morphology of ǃXoon, for voiceless-voiced pairs of click clusters led to the discovery of several series not distinguished by Traill. (This morphology appears to be more pervasive in West ǃXoon than in the East ǃXoon dialect that Traill worked on.) These are voiced click types which may not exist in East ǃXoon at all, namely "nꞰʼʼ, nꞰhh, gꞰʼ," and "gꞰqʼ." It also lead to the rediscovery of two series that Traill had not been able to publish before his death. Thus the DoBeS team distinguishes two series, "Ʞqh" and "Ʞh," for Trail's "Ʞqh" and "Ʞkh", as well as "Ʞʼʼ" and "Ʞʼ" for Traill's "Ʞqʼ" and "Ʞkʼ" (or perhaps vice versa). If Traill's "Ʞkh" series is to be analyzed as "kꞰ + h", then that would require a different assessment of Traill's delayed-aspiration series.
