Intrusion

Intrusion in phonetics refers to the phenomenon where an additional sound is inserted between words or syllables during speech. This often occurs to make pronunciation easier or more fluid. For example, in English, an intrusive /r/ might appear in phrases like "law(r) and order" or "saw(r) it." Understanding intrusion helps language learners achieve more natural-sounding speech and improves their listening comprehension. Teachers can address intrusion by providing listening practice, highlighting instances of intrusion in spoken language, and offering pronunciation exercises.
