How do you pronounce “actually”?

Actual is correctly pronounced with a tʃ (ʃ = sh as in sharp) sound after the t.

If I were to pronounce it like this “ækshually” because I have trouble adding the t unless I make an excessive stop would that be okay?

No one’s going to notice or care if you pronounce ct as a non-aspirated k and follow it with a ʃ (sh) with no t, and this is how people say it quickly or when not emphasizing the word.

Pronouncing it correctly definitely involves a firm stop. Ask a native speaker to repeat the word slowly and very clearly, and they will do the same.

A hidden ʃ is often added after t in some words, particularly with tr and ctu – e.g. sanctuary, trade, try, triangle.
