Both IELTS and TOEFL deliberately mix accents β British, North American, Australian, New Zealand. If you've only ever practised with one, an unfamiliar accent on test day can cost you an entire section while your ear adjusts.
Each accent shifts vowels, rhythm and connected-speech patterns. Australian and New Zealand vowels sit differently; British non-rhotic speech drops many /r/ sounds; American speech flaps the /t/ in "water" to a soft /d/. The words are the same β the surface sound isn't.
The way to remove the surprise is exposure under exam conditions: full-length mock sections, played once, with the speakers changing from section to section β then reviewed to see where you lost marks. Familiarity turns "I couldn't understand them" into "I've heard this before."
Lisenia's mock papers rotate British, North American, Australian and New Zealand voices the way the real exams do β the speakers change between sections, so you are never carried along by one familiar voice. Your result then shows which listening skills cost you the marks, so you know what to train next. Start with the free diagnostic.
