Not relevant! Here were'e not speaking about punctuation between words, but
inclusion within words in phonetic trancrtiptions where even word
separation is not always relevant and punctuation us almost absent.
There's no case in Spanish with "¡" in the middle of a word. But here we're
speaking about noting a consonant within words where vowels can also be
expected in phonetic transcriptions. And there the confusion with a
following voiwel i is very likely. On the opposite, IPA symbols are
carefully chosen to avoid visual confusions (and that's why they only exist
in a single lettercase).
