The International Phonetic Alphabet, or IPA, is an alphabetic system of phonetic notation based primarily on the Latin alphabet.
It was created by the International Phonetic Association as a standardized representation of the sounds of spoken language and is used by lexicographers, foreign language students and teachers, linguists, speech-language pathologists, singers, actors, constructed language creators, and translators.
The symbols are made up of one or more elements of two basic types, letters and diacritics. For example, the sound of the English letter "t," may be transcribed in IPA with a single letter, "t," or with a letter plus diacritics, "t̺ʰ."
Slashes are frequently used to signal broad or phonemic transcription; thus, /t/ is less specific and could refer to, either "t̺ʰ" or "t," depending on the context and language.
