|Ai-|Ais/Richtersveld Transfrontier Park: Journey through other-worldly desert scenery

[@jimgreen5788]

Being a foreigner (American) who's visited S. Africa, I'm curious as to the pronunciation of |Ai-|Ais, or (wasn't it originally?) !Ai-!Ais. Do the San letters match up with Xhosa's "gidyap horse" (x) click, the 'tisk' click (c), or the tongue click (q), all unvoiced, or the voiced versions (xh, nc, gq)? Thanks/Dankie.
