Assertion: vowel's sound | /r/Causes | fewer systematic changes
Facets:
value: in neighbouring vowel formants
type: OTHER
Source sentences:
text: cause a lowering of the formants; velar sounds (/k/ and /ɡ/ in English) almost always show F 2 and F 3 coming together in a 'velar pinch' before the velar and separating from the same 'pinch' as the velar is released; alveolar sounds (English /t/ and /d/) cause fewer systematic changes in neighbouring vowel formants, depending partially on exactly which vowel is present.
