Juno confused her silly tongue 

Juno confused
her silly tongue, because she often held
that glorious goddess with her endless tales,
till many a hapless Nymph, from Jove's embrace,
had made escape adown a mountain. But
for this, the goddess might have caught them. Thus
the glorious Juno, when she knew her guile;
“Your tongue, so freely wagged at my expense,
shall be of little use; your endless voice,
much shorter than your tongue.” At once the Nymph
was stricken as the goddess had decreed;--
and, ever since, she only mocks the sounds
of others' voices, or, perchance, returns
their final words.

-Ovid, Metamorphoses
