Although spectrograms contain much more detail, I'm curious how far phonologists and phoneticists can go with IPA alone. Can someone provide some examples of narrow, detail-rich IPA transcription for various words in English, Spanish, German, Icelandic, etc.? I'd also be interested in seeing how IPA can capture existing phonetic features such as allophones, etc.
Alternatively, what detail can be denoted in a spectrogram but not IPA?
I've found the following examples of what I'm looking for on Wikipedia:
- pets [pʰɛʔts]
- pretzel [ˈpʰɹ̥ʷɛʔt.sɫ̩]
