Balancing Formality in Speaking Without Sounding Stiff

Candidates preparing for Speaking often make one of two opposite mistakes with register: treating the interview like a formal written test and speaking in stiff, essay-like sentences, or treating it like a casual chat with a friend and using slang or fragments an examiner may find under-considered for an exam context. Both miss the actual target, which sits in a specific middle zone — natural, conversational, but still appropriately considered, because you are speaking with an examiner you've just met in a semi-formal interview, not writing an essay and not chatting with someone you know well.

It helps to think of three points on a scale. At one end sits Task 2 essay writing: full grammatical forms, no contractions, formal connectors like "furthermore" and "it could be argued that." At the other end sits fully casual conversation with a close friend: slang, incomplete sentences, heavy use of filler words like "like" and "basically." Speaking sits between these — noticeably less formal than essay writing, but more complete and considered than fully casual talk. Landing consistently near either extreme, rather than in this middle zone, reads as miscalibrated to the actual context.

Contractions are a clear, practical marker of this middle register. "I'm," "don't," "it's," and "I'd" are entirely natural and expected throughout a Speaking test; consistently avoiding them in favour of "I am," "do not," and "it is" doesn't sound more formal or impressive, it sounds stiff and rehearsed, working against the natural fluency examiners are actually listening for. Compare "I do not think that I would enjoy that" with "I don't think I'd enjoy that" — the second sounds like genuine, natural speech; the first sounds like a sentence read aloud from an essay.

One specific, easy-to-spot register error is importing essay-style discourse markers into spoken answers: opening a Part 1 answer with "Moreover, I would state that..." or "In conclusion, my opinion is..." borrows connectors built for written paragraphs, and using them in speech reads as noticeably over-formal, almost as though reciting a memorised paragraph rather than answering conversationally. The spoken equivalents of the same logical function — "also," "so basically," "anyway, my overall view is..." — carry the same meaning while actually sounding like something a person would say out loud, which is exactly the natural register Speaking is trying to assess.

At the other end, expressions suited to talking with close friends can read as under-considered in an exam interview. "Yeah, whatever, I guess it's fine" or heavily overusing "like" as filler ("it was, like, really, like, difficult") both suggest a register calibrated for a casual context rather than a semi-formal one. This doesn't mean sounding rigid or overly careful — it means choosing natural but slightly more complete phrasing, such as "I guess it's fine, to be honest" rather than "yeah, whatever."

A specific, useful tool for hitting the right register is the kind of small politeness marker natural between someone and a person they've just met: "that's actually a good question," "I hadn't really thought about that before, but...," "that's an interesting way to put it." These phrases do real work — they buy a moment to think, they sound genuinely natural in this specific context, and they avoid both stiff formality and unfiltered casualness at the same time.
