Protonation of amines gives-      RNH_{2}\rightarrow RNH^{-}+H^{+}  (amide ion)
protonation of alcohol givesR-OH\rightarrow RO^{-}+H^{+}   (alkoxide ion)

the negative charge is easily accommodated by O atom because it is more electronegative than N atom. So, the amide ion is less stable than the alkoxide ion. Hence amines are less acidic than alcohols.
