Pronunciation
To pronounce the digraph DZ, block the air with the tip your tongue and your alveolar ridge and push your diaphragm to create an air pressure. Then, release the air and create friction by keeping the tip of your tongue close to the alveolar ridge. Not less important, slightly close your vocal chords and vibrate them.

the sound of the digraph DZ is basically the sound of the letter D and then the sound of the letter Z, but pronounced in a row.
