 In the 1950s and 1960s, older speakers retained palatal stops /c, c'/ where younger speakers used an innovative palatal affricate [tʃ], [tʃʼ], perhaps under influence from English.The notation /j/ represents the palatal glide, the same as the spelling "y" in English "yes".The voiced plosives (/b/ & /d/) are implosive, but do not contrast with simple voiced stops.
