English is a complex language with several pronunciation rules dependent on word length, vowel and consonant placement and the context in which a particular word is used. Some rules are definitive, such as the requirement of every English word to have a vowel.
There are basic guidelines for consonants and vowels that are helpful for understanding how to pronounce words. The English language has five vowels: a, e, i, o and u. For words that only have consonants such as "dry" or "why," the letter "y" acts as a vowel. The rules for consonant pronunciation tend to be more situational. For instance, the letter "b" is typically pronounced with a long sound at the beginning of a word, like "bear" or "bond." However, for words that end in the letter "b" such as "climb," the "b" is silent.
Each English word also has a certain number of syllables that dictate the pace at which the word is pronounced. Generally, the number of syllables in a word is equivalent to the number of vowel sounds heard when the word is vocalized. The recommended method to properly learn the rules of English pronunciation is to consistently practice by communicating with English speakers.
