Which vowel sound example corresponds to "ɑ"?

The vowel sound represented by "ɑ" is typically found in words where the vowel is pronounced with an open back unround articulation. In this case, the example "Cod" features the "ɑ" sound, which is articulated in a way that the mouth is open, and the back of the tongue is positioned low and towards the back of the mouth.

The sound is characterized by its warmth and depth, which reflects the qualities of the vowel in "Cod." This is in contrast to other options where the vowel sounds do not correspond to the characteristics of "ɑ." For example, "Boat" contains the diphthong sound represented by "oʊ," while "Wood" contains a rounded vowel sound, and "Pool" includes a different rounded vowel sound. Each of these examples demonstrates different vowel qualities that are distinct from the open back unrounded sound found in "Cod."
