The International Phonetic Alphabet attempts a universal notation for every speech sound

Evidence

Phonetics is the science that has developed ways to analyse and describe speech units and their features and structures composed of speech units (Ashby and Maidment, 2005). Various textual or symbolic notations exist to characterize how the units in speech are pronounced, both for practical guidance in dictionaries and for scientific purposes. An attempt to make a universal notation for any speech sound in any language has been taken in the International Phonetic Alphabet (IPA) (International Phonetic Association, 2014). The IPA notation is used in the examples within this book. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 568
