The Study
Differentiating Between Human-Written and AI-Generated Texts Using Automatically Extracted Linguistic Features
This study compared 5 essays written by people and 5 written by a robot, then counted things like how many nouns or long words each used. It found some patterns, like the robot used more big words. But it didn't prove the robot caused those differences—it just showed what was different in these 10 essays.
Analysis score
Maximum 0 for a computational/algorithm study.
Where the score came from
AI writes essays that look smart but sound robotic because it uses fancy words and long sentences but forgets to use little words that make speech feel natural.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — these patterns make AI text feel stiff and unnatural to readers, even if it’s grammatically correct.
- 2AI used 30% more big words, 40% fewer pronouns like 'I' or 'they', and preferred hard consonants like 't' and 'k' over softer ones like 'd' and 'v'.

Speech generated by artificial intelligence often sounds unnatural because it leaves out words that connect ideas and creates abrupt shifts between sentences.
Text generated by artificial intelligence uses more voiceless and alveolar consonants and fewer dental and labiodental consonants than text written by humans, reflecting differences in how the model translates written symbols into sound patterns.
AI-generated text uses more connecting words and descriptive adjectives but fewer phrases that show relationships between things and fewer pronouns than text written by humans.
AI-generated writing uses more complex nouns and connecting words than human writing, while human writing uses more pronouns and simple grammatical elements, making AI text more formal and uniform and human text more varied and reference-rich.
Text written by artificial intelligence uses more complex and rare words than text written by people, while human writing uses more common grammatical words like 'the', 'and', and 'is.
Automated linguistic analysis tools can distinguish between essays written by humans and those generated by artificial intelligence with statistical reliability in controlled tests.
