Phonemic hearing disorders – difficulties in perceiving speech sounds, i.e. in distinguishing between sounds and their distinctive features (e.g. z-s sounds, which differ by only one distinctive feature – sonority).

These disorders make it difficult for the child to distinguish phonetically similar sounds, because they are similar acoustically and articulately, and therefore differ by only one distinctive feature. Hence the difficulties in distinguishing words from each other and writing them correctly.
