Primary and secondary lexical stresses differ in acoustic prominence.
Is it true that primary and secondary lexical stresses differ in acoustic prominence?
The claim that primary and secondary lexical stresses differ in acoustic prominence is a definitional property of linguistic stress hierarchies, making it common knowledge that requires no citation.
Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked
The claim states that primary and secondary lexical stresses differ in acoustic prominence. This is a foundational, definitional concept in linguistics and phonetics: stress levels are hierarchically defined precisely by degrees of relative acoustic prominence (such as differences in fundamental frequency, intensity, and duration). Because this is a matter of standard linguistic definition and direct observation of multi-syllabic stress patterns, it falls under STEP 0 as common knowledge requiring no citation.
