Thank you very much! It works.
I didn't understand you right in your previous post and used \textsubcircum inside the \textipa command, instead of plain.
Now that the problem is solved, please be so kind and mark the topic accordingly as clearly written in Section 3 of the Board Rules (to be read before posting). You are not new to the forum so you should know that. Please keep that in mind for the future so that further reminders will not be necessary.
