Explanation: the number of sounds in a word is like when you are teaching a baby to pronounce a word. Doesn’t matter the language you sound out he sounds technically letter by letter. In Spanish you didn’t separate some letter when you sound out them. An example ll, qu, ch and letter h following by a vowel since the h in Spanish do not have sound except when is next to a c.
