Phonetic notation of the American Heritage Dictionary explained

pronounced as /notice/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.
