extramatrical

Extramatrical refers to a term used in the field of linguistics and phonetics to describe sounds or speech events that occur outside the normal, expected, or standard patterns of a language. These sounds are not part of the phonemic inventory of the language and are often considered extraneous or non-native to the language system. Extramatrical sounds can include various phenomena such as mispronunciations, foreign accents, or non-standard dialects. They are typically not subject to the same phonological rules as the standard sounds of the language and may be perceived as errors or deviations from the norm. The study of extramatrical sounds is important for understanding the flexibility and adaptability of language systems, as well as for identifying and correcting pronunciation errors in language learning and teaching.
