Phonetic notation of the American Heritage Dictionary
# Phonetic notation of the American Heritage Dictionary

The American Heritage Dictionary of the English Language (abbreviated AHD) uses a phonetic notation based on the Latin alphabet 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.

The following tables show the AHD representations of English phonemes, along with the IPA equivalents as used on Wikipedia.

## Vowels

In general, long vowels are marked with a macron, and short vowels with a breve. A circumflex may also be used to indicate a pre-rhotic vowel. Usage of other symbols vary.
