pronouncing "y" as "dz"?

Khmer verb "ywol" that means to understand, I saw the IPA pronouncing symbol expression but I heard "dzwol" from a native speaker. That seems like Spanish speakers speaks "dz" for "y". Are there two tongues, people pronounces "y" and other people does "dz" in Khmer? or difficulty of pronouncing "y" like Spanish?
