It has been many months since I tested anything on ChatGPT. But it occurred to me to ask if it could generate text containing all the phonemes of American English. So I asked, and it did. It offered to "spotlight" the vowels and consonants. I said yes. It listed examples.
Here's one sample:
/i/ – Eliot, heirs, shrill
For you non-linguists, this /i/ represents the 'long e' sound in "see". So using the the IPA (international phonetic alphabet) , the word "see" would be written /si/.
Hmm. 'Eliot' has that 'long e' sound. But 'heirs' doesn't, nor does 'shrill.'
Two wrong out of three? Can't recommend that to my students.
I checked some other parts and the error rate was about the same. As is often reported, it's faster to do it yourself than to correct the errors the bot makes. And for non-native speakers it's a potential nightmare. Oh well.
