It is quite another thing to say that Paul misspoke.

Paul had apostolic authority. Luke’s writings are included in the cannon largely because of his association with Paul. So it’s odd to say that Luke correctly reports Paul’s conversion and correctly reports Paul’s own incorrect rendition of that conversion. I think this is one place where indirect speech reported by Scripture must be harmonized with the direct testimony of Scripture.

I suppose that this is a long-winded way of voting for the second inerrantist response above.

Matthew 13:13 is relevant here: “The reason I speak to them in parables is that ‘seeing they do not perceive, and hearing they do not listen, nor do they understand.’” [NRSV]

In the phrase “hearing they do not listen”, the verb ακουω is used twice, but the NRSV has used two different English verbs to reflect the fact that it’s being used in two different ways.

This gives support to the idea that ακουω has a sufficient range of meaning that hearing is something that you can both do and not do at the same time.

I’ll add it as a possible inerrantist response.
