Materials published elsewhere use somewhat different conventions from those used at Wikipedia. For example, it is a longstanding tradition to leave velarized ("broad") consonants unmarked and mark palatalized ("slender") consonants with the prime, but that is not standard IPA usage.

This section compares the IPA system used at Wikipedia (which is based on that used by Ailbhe Ní Chasaide in her description of Irish in the Handbook of the International Phonetic Association, ISBN 0-521-63751-1) with the systems used in some other works.
