Wikipedia:American Heritage Dictionary representation

The American Heritage Dictionary representation (abbreviated AHD) is a phonetic notation, based on the Latin alphabet, used by the American Heritage Dictionary of the English Language to transcribe the pronunciation of spoken English. It and similar respelling systems, such as those used by the Merriam Webster and Random House dictionaries, are familiar to US schoolchildren. Except for minor formatting of the stress marks, it is identical to the system used on Wiktionary, where it is called the English Phonemic Representation (abbreviated enPR).

The following tables show the AHD representations of English phonemes,[1] along with the IPA equivalents as used on Wikipedia:

VowelsEdit

Because they behave differently among English dialects, rhotic vowels are listed separately. Many US speakers conflate âr, ăr, and ĕr; îr and ĭr; ōr, ôr, and ŏr; ûr and ŭr. Among non-rhotic vowels, many conflate ä, ô, and ŏ.
