Is it true that several natural human languages and dialects contain true triphthongs?
Yes. Multiple linguistic and phonetic studies analyzing Romance and Germanic languages document the existence and acoustic properties of triphthongs in natural human languages.
Verdict: SUPPORTED · 2 sources for, 0 against · Last checked
The analysis
The claim states that several natural human languages contain true triphthongs. Papers 10 and 11 explicitly discuss triphthongs within specific natural languages (Romance languages and Modern German) and analyze their articulatory or acoustic characteristics. None of the papers refute the claim, leading to a supported verdict.
