I think he was wrong. There's no doubt that hearing a poem read aloud
enhances -- that is enhances the later silent reading of it. Much of the
sound value of poetry can only be heard in the head as one reads
silently. Particularly cadence tends to get damped when the poem is read
aloud (though again, a good reading aloud can change the quality of
one's later silent reading).
Those lines from Pope I quoted are really a special case. Most good
verse has several sounds or sound patterns, and to read aloud kills all
the patterns except the one chosen by the reader. In a silent reading
one can "hear" them all at once.
