Stresses dialects (7)

I believe the answer is:

accents

I believe this is a double definition.

'stresses' is the first definition.
('accent' can be a synonym of 'stress')

'dialects' is the second definition.
('accent' can be a synonym of 'dialect')

(Other definitions for accents that I've seen before include "Local ways of speaking" , "Strongly contrasting details" , "Dialects, articulations" , "graves?" , "Stresses" .)

I've seen this clue in The Mirror.
