What are the two vowel sounds known in Spanish?

In Spanish, the language is fundamentally characterized by its vowel sounds, which are critical to pronunciation and understanding. Spanish has five distinct vowel sounds, corresponding to the vowels A, E, I, O, and U.

These vowels have specific pronunciations that are generally consistent, unlike in English, where vowel sounds can vary drastically depending on the word. For instance, the vowel 'A' is pronounced as [a], 'E' as [e], 'I' as [i], 'O' as [o], and 'U' as [u]. This simplicity in vowel sounds contributes to the clarity and rhythm of spoken Spanish, making it easier for learners to master pronunciation.

The other options suggest a greater number of vowel sounds than what exists in standard Spanish phonetics. While variations and diphthongs might add complexity to pronunciation in practice, the foundational aspect of Spanish vowel sounds remains at five. Therefore, recognizing this structure is essential for anyone learning the language or studying its phonetics.
