The Study
LINGUISTIC DOMAINS: COMPARISON OF TEXTS WRITTEN BY HUMAN AND ARTIFICIAL INTELLIGENCE
This study looked at 10 essays written by people and 10 written by a robot, then counted how many nouns, verbs, and fancy words each used. It found some differences, like the robot using more big words. But it didn’t prove the robot caused those differences — it just showed a pattern in these 20 essays.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — these differences make AI writing sound more robotic and less natural, even when it's grammatically correct.
- 2AI used more big words, nouns, and connectors like 'and' or 'but'; people used more verbs, helper words like 'is' or 'has', and phrases like 'in the park' or 'with friends'.

Speech generated by artificial intelligence often sounds unnatural because it leaves out words that connect ideas and creates abrupt shifts between sentences.
AI-written text uses harder words and more content-heavy language, while human-written text uses simpler words focused on function and clarity.
AI-generated text uses more nouns, complex words, and certain grammatical structures than human-written text, while human text uses more verbs, prepositions, and basic function words.
Human-written essays use more prepositional phrases and embedded descriptions, while AI-generated texts use more direct objects and connecting words, resulting in more segmented sentence structures.
Automated linguistic analysis tools can consistently identify measurable differences in language patterns between text written by humans and text generated by artificial intelligence.
