phonemic paraphasia
Speech error where patients substitute sounds within words, creating phonetically similar but incorrect versions of intended words.
Full Definition
Phonemic paraphasia is a type of language error commonly observed in aphasia where patients inadvertently substitute, add, or omit phonemes (speech sounds) within words. This results in spoken words that sound similar to the intended target but are phonetically distorted. For example, a patient might say "spoon" instead of "spoon" or "ttelephone" instead of "telephone." This phenomenon differs from semantic paraphasia, where entire words are substituted with semantically related alternatives. Phonemic paraphasias are particularly common in conduction aphasia and can provide important diagnostic information about the location and nature of language processing deficits.
Usage
Usage note: Distinguish from semantic paraphasia in clinical documentation; specify whether errors involve sound substitution, addition, or omission.
