In this video, I go over the pronunciation pattern for words that contain “all” or “alk”. It’s pretty straight forward and even native English speakers are usually aware how these words work.
The one possible issue is that the North American pronunciation of these syllables are in the process of a shift. In my opinion, the best way to go is to get your students to learn your own accent first. If they are successful, it will be easier to hear and imitate others in the future.
