Diacritic marks for katakana work in the same way as those in hiragana.

	Two short strokes attached to the right shoulder of the symbols can change the voiceless /k/, /s/, /t/ and /h/ sounds to the respective voiced sounds of /g/, /z/, /d/ and /b/ (e.g., カ ⇒ ガ).
	A small circle attached to the right shoulder of the /h/ column symbols changes the /h/ sound to the /p/ sound (e.g., ハ ⇒ パ).

Click on each box and hear how the diacritics change the sound of each katakana. Note that characters ジ and ヂ have the same sound /ji/ . Also, characters ズ and ヅ have the same sound /zu/. When writing foreign words that involve /ji/ and /zu/ sounds, ジ and ズ are used respectively, and ヂ and ヅ are not used.
