Poor quality of voice is sneered about (9)

I believe the answer is:

reediness

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

'poor quality of voice' is the definition.
The definition suggests a singular noun which matches the answer.

'is sneered about' is the wordplay.
'about' indicates an anagram.
'is'+'sneered'='issneered'
'issneered' is an anagram of 'REEDINESS'.

Can you help me to learn more?

(Other definitions for reediness that I've seen before include "characteristic of marshes" , "Quality of some birdsong" .)
