The Merriam-Webster Phonetic Alphabet (MWPA) is primarily used by the Merriam-Webster dictionary for providing phonetic transcriptions of English words. It is widely used in English-speaking countries, particularly in the United States, where Merriam-Webster is based. However, it's important to note that the MWPA is not an official standard like the International Phonetic Alphabet (IPA), which is used more universally across different languages and countries.

In British English, the International Phonetic Alphabet (IPA) is more commonly used for phonetic transcriptions compared to the Merriam-Webster Phonetic Alphabet (MWPA). While the MWPA is associated with American English dictionaries such as Merriam-Webster, the IPA is widely used by British dictionaries, language learners, linguists, and educators to provide accurate phonetic representations of words in British English and other languages.
