This error is linked to particular dialects of English. For some individuals, the word ask poses a problem. You may have heard sentences such as, “May I ax you a question?” Of course, the speaker intends to say ask, but the s and k sounds are transposed so that it sounds like ax, as in the tool used to chop wood. For those who have difficulty pronouncing this word, just remember that the s comes before the k, not the other way around. (Listen)
I don’t agree. This varies by dialect. In African-American Vernacular English, this pronunciation is accepted and internally valid. I think you’re talking about “regionally-appropriate”, not “correct” pronunciation
