This category is triggered if {{IPAc-en}} is used with unsupported parameters, such as a word not broken up into phonemes, non-English phonemes, or an audio file not preceded by 'audio='.

Some IPA templates appear here because of their coding, and can be ignored.

If you have come here because of a malfunctioning IPA template and don't know how to fix it, drop a note at Help talk:IPA for English.
