Ila some sounds


 * ch in fact varies from "k" to a "weak" version of English "ch", to a "strong" "ch" to "ty".
 * j as the voiced sound corresponding to this therefore varies "g"/English "j"/ "dy" / and "y".
 * v is reportedly like English "v", but vh "lips more rounded with a more distinct emission of breath".
 * zh is the j in French bonjour.
 * ng is the sound as in (southern British) English "finger", while ng'  is as in "singer" - a similar distinction is observed in Swahili.
