I haven't heard recordings of Venda, but I have a Venda dictionary I found at a Half Price Books, which has a note about the sounds written as "fh" and "vh": "fh, vh are voiceless and voiced bilabial fricatives". I assume that plain "f" and "v" are labiodental fricatives, but that's not explicitly stated. A language with all three of bilabial, labiodental, and dental fricatives would be problematic in Kjaginic script, but I could use dots to distinguish those as the older Tharkania system uses.
