'raise article associated with the speaker in appropriate' is the wordplay.

'article' becomes 'an' (indefinite article).
'associated with the speaker' becomes 'my' (associated with the person speaking).
'in' indicates putting letters inside.
'appropriate' becomes 'apt' ('apt' can be a synonym of 'appropriate').
'my' going within 'apt' is 'apmyt'.
'an'+'apmyt'='anapmyt'
'anapmyt' reversed gives 'TYMPANA'.
