Hello,

When using IPA, I am aware that <.> (full stop) represents a syllable break.
However, I have also read that a <-> can also be used? Is this correct? If so, is it simply a matter of personal preference, or is one considered better or more appropriate than the other? Also, what kind of hyphen is it (is it an em dash, regular hypen, etc?)

Thanks for your help!

The use of a hyphen is, however, standard for marking morpheme boundaries, usually not in the context of a phonetic transcription (unless your orthography happens to be IPA, as is the case, rarely, for some descriptive grammars, but then just as normal letters not in slashes/brackets).

I suppose you might end up with a transcription between slashes that has hyphens to show morpheme boundaries, but just like word boundaries, that is usually not marked in IPA, and as far as I know not standard/recommended, and either way not narrowly a phonological (but morphological) question. In doing so, you'd be mixing up several tiers of description and it could get confusing fast.
