Step-by-step explanation:
The universal alphabet of all potential sounds based on how they are produced is called the International Phonetic Alphabet (IPA). The IPA is a system of phonetic notation that uses a set of symbols to represent each individual sound used in spoken human language. It includes symbols for consonants, vowels, diacritics, and suprasegmental features like stress and tone. The IPA is widely used by linguists, language teachers, and speech pathologists to accurately transcribe and describe the sounds of languages.
