Vocal accents adding weight to certain points (5)

I believe the answer is:

tones

I'm a little stuck... Click here to teach me more about this clue!

'vocal accents adding' is the definition.
I can't judge whether this defines the answer.

'weight to certain points' is the wordplay.
'weight' becomes 'ton' (unit of weight).
'to' is a charade indicator (letters next to each other).
'certain points' becomes 'es' (E is an example. I am not sure about the 'certain' bit.).
'ton'+'es'='TONES'

Can you help me to learn more?

(Other definitions for tones that I've seen before include "Notes, characters" , "Told about the silly ass" , "Tints of colour" , "Shades" , "Qualities of people's voices" .)
