The word "batat" is not a commonly used word in English, but it could refer to sweet potato in some languages. The spelling of "batat" can be broken down into three phonetic sounds: /bəˈtæt/. The first sound is a schwa, meaning it is an unstressed vowel sound. The second sound is a voiced bilabial stop, which is the "b" sound. The third sound is an unvoiced alveolar stop, which is the "t" sound. When spoken together, these three sounds come out as "buh-tat."
