IPABCDE

IPA (International Phonetic Alphabet) is a system of phonetic notation devised by the International Phonetic Association to transcribe the sounds of spoken language. The terms IPABCDE refer to a specific set of IPA symbols that represent vowel sounds. These symbols are used to denote the quality of a vowel sound in terms of its position in the mouth and the shape of the lips.

The symbol "i" represents a close front unrounded vowel, which is the sound heard in the English word "see." The symbol "e" denotes a close-mid front unrounded vowel, as in the English word "bay." The symbol "ɛ" (epsilon) represents an open-mid front unrounded vowel, similar to the sound in the English word "bed."

The symbol "a" stands for an open central unrounded vowel, which is the sound heard in the English word "father." The symbol "ɑ" (alpha) denotes an open back unrounded vowel, as in the English word "cot." The symbol "o" represents a close-mid back rounded vowel, similar to the sound in the English word "go." Finally, the symbol "u" stands for a close back rounded vowel, as in the English word "shoe."

These symbols are part of a broader system that includes diacritics and other modifications to represent a wide range of vowel sounds found in languages around the world. The IPABCDE system is widely used in linguistics, language teaching, and speech therapy to provide a precise and standardized way to describe and transcribe vowel sounds.
