About the IPA
The International Phonetic Alphabet is a standardized system of symbols used to represent the sounds of spoken language.
It helps linguists, language learners, and educators accurately describe pronunciation across languages.
Example: the word "hello" in British English is transcribed as /həˈləʊ/ in IPA.
