Direct answer
You make text sound human by changing how predictable it is, not by sprinkling in contractions and casual words. AI detectors such as Turnitin's measure statistical predictability across sentence spans, so the reliable fix is to vary sentence length, replace generic phrasing with specific detail, and rebuild paragraphs around your own reasoning order [1]. Surface polish alone will not move a score, because detectors respond to the underlying word-sequence patterns rather than to tone [1].
What Makes Writing Sound AI-Generated Instead of Human?
Machine-sounding prose has a recognisable statistical signature: evenly paced sentences, hedged claims, and transitions that announce structure instead of carrying meaning. Turnitin's AI Writing Report is segment-based, meaning it evaluates chunks of your document and highlights the specific spans it flags rather than issuing one opaque number [2]. That design matters for revision, because it tells you the problem is local — a handful of paragraphs — rather than a property of your whole essay [2].
The percentage you see is a share of qualifying text, not a probability that you cheated. A 6,000-word dissertation can show a modest overall figure while two literature-review paragraphs carry almost all of the flagged content [2]. Turnitin also presents the report as a signal that prompts a conversation about the writing process, not as a verdict, and institutions are expected to weigh context and drafting evidence alongside the number [2].
This is why "make it sound human" is the wrong mental model. A paragraph can be fluent, grammatical, and pleasant to read while still being highly predictable — and predictability is what the detector is actually measuring [1]. Conversely, a plainly written human paragraph with uneven rhythm and oddly specific detail often scores clean even though it reads less smoothly [1]. Aim for specificity and irregularity, not for charm.
Which Specific Edits Make a Paragraph Sound More Human?
Start at sentence level, because that is the level reviewers and detectors both work at. Instructors open the report inside the LMS and read flagged spans sentence by sentence against your original submission, so a rewrite that only swaps synonyms will be visible as a rewrite and may still be flagged [3]. The report also separates AI-generated text from AI-paraphrased text, which means lightly edited machine output is its own category rather than a safe middle ground [3].
The edits that actually shift a paragraph are structural. Break one long, balanced sentence into a short claim followed by a longer qualification. Delete the opening clause that announces what you are about to say. Replace an abstract noun phrase with a named study, a date, a figure, or a disagreement between two authors. Reorder the paragraph so it follows the sequence in which you actually thought it through, rather than the sequence a template would produce [3].
Then do a specificity audit. Every paragraph should contain at least one thing that could only have come from your reading: a page number, a quoted phrase, a methodological quirk, a limitation you noticed. Generic connective tissue — "furthermore", "it is important to note", "in today's rapidly evolving landscape" — is where predictability concentrates, and it is also the easiest material to cut [3].
Finally, read the revision aloud. Human academic writing has uneven breath: a three-word sentence after a forty-word one, an aside in parentheses, a concession that interrupts the argument before it resumes. Because the report is segment-based, targeted revision of the paragraphs that were flagged moves the overall figure far more than a light pass over the entire document [3].
How Do I Check Whether My Rewritten Text Still Reads as AI to Turnitin?
You cannot self-assess this reliably, because the signal you are trying to remove is invisible to the person who wrote the text. The practical route is a pre-submission check against the same detection engine your institution uses, then a second check after you revise, so you can see whether the flagged spans actually moved [1]. Two data points — before and after — tell you whether your editing method works; one number tells you nothing about direction [1].
Context decides how much the number matters. Institutions set their own thresholds and their own policies on AI assistance, and Turnitin positions its reports as evidence to be interpreted alongside the drafting process rather than as an automatic finding [4]. That means the useful question is not "can I get to zero" but "can I show, with a report and a revision trail, that the flagged passages no longer reflect how this text was produced" [4].
Turnitin's confidence threshold is the detail most students miss. When the AI signal falls below 20% confidence, the report displays *% instead of an exact percentage, because the underlying evidence is weak [1]. A *% result is therefore a low-confidence reading, not a guaranteed pass — and it is worth understanding before you decide whether to keep revising or to stop [1].
Manual revision gets most students a long way, but the last few flagged paragraphs are usually the stubborn ones — the sections where your own phrasing happens to mirror the patterns detectors look for. That is exactly the point where turnitin0 becomes useful: upload the draft, get the same Turnitin AI and similarity reports your tutor sees, and let the flagged spans tell you precisely which paragraphs still need work.

FAQ
Does adding contractions and casual words make text sound human?
Not meaningfully. Detectors respond to statistical predictability in word sequences, so tone tweaks leave the underlying pattern intact [1]. Sentence variety, concrete detail, and genuine reasoning order do the real work.
Is a *% result on the Turnitin AI report a pass?
It means the AI signal fell below Turnitin's 20% confidence threshold, so the report shows an asterisk instead of an exact figure [1]. Treat it as a low-confidence reading rather than a guarantee.
Will rewriting flagged paragraphs lower my overall score?
Usually, because the AI Writing Report is segment-based and the headline figure reflects the share of qualifying text that was flagged [2]. Rebuilding the specific spans the report highlights is more effective than editing the whole document evenly [3].
Can my tutor tell that I edited AI text rather than wrote it myself?
The report distinguishes AI-generated from AI-paraphrased content, and reviewers read flagged spans against your submission sentence by sentence [3]. Institutions are also expected to weigh drafting evidence and context, so keeping your notes and earlier drafts matters [4].
How many times should I re-check before submitting?
Checking once before revision and once after is enough to confirm your method is working. Compare which spans moved rather than chasing a single number [1].
