👉 The process of "acetalization" involves changing a consonant sound, typically voiced (i.e. "a"), to an aspirated vowel (i.e. "ə"). This is commonly done in certain dialects or languages such as the French 'é' and German 'ä' sounds. Acetalizations are often used in words where the original consonant sound does not convey the intended meaning, such as when a word becomes difficult to pronounce or when there is ambiguity in its context.
