The word "zapato" is Spanish for "shoe," and it is used in various Spanish-speaking countries. However, the pronunciation might give clues as to the speaker's origin. Generally, unless there’s specific context or accent in the audio, it’s difficult to determine the country just from the word alone.
If you cannot hear the audio, I recommend checking for accent cues or other contextual hints to make a better guess. If pressed for a response based on just the word, I would lean towards Mexico as it's one of the more common regions associated with the term in daily use.
