Spanish is not as complicated as English pronunciation rules. Almost every letter has only one specific pronunciation. For example, the letter A is pronounced "a" at any time, and the letter E is pronounced "alas" (with a small mouth, similar to the English E). There is only one sound in Spanish that is difficult to pronounce, that is, the letter R, which is Lickitung's trill. In fact, the most difficult thing in Spanish is not pronunciation, but the deviation of grammar and verbs. Also, its speech speed is not generally fast, so be prepared psychologically, which is not an order of magnitude with English! ! I suggest you buy a book in Spanish in advance, because it is much more difficult to learn than English.
Beginners must read Spanish, which is more scientific than English. It is a phonetic symbol without phonetic symbols. After mastering the pronunciation rules, they can "look at the pronunciation of words". After a brief introduction and good study, you can read all Spanish articles fluently, which is the first level!
