William: Hmmm, I know! In that clip we heard a soldier /ˈsoʊltər/telling his men to hold their horses before he started firing weapons.
Li: But nowadays, I am guessing, you don't need to be a soldier
/ˈsoʊlər/ to use this phrase, right?

soldier (ˈsoʊlər )
Checking many dictionaries havent helped me figure out the first pronunciation of the word soldier in that clip. It seems to me /ˈsoʊltər/. I don't say that this is a regional accent. Native English speakers will decide whether it voiceless stop /ˈsoʊltər/ or /ˈsoʊlər/ voiced alveopalatal affricate. Will you clear it up, please?
