why are we using H3O+ in the case of preparation of aldehydes in Stephen reaction while in case of hydrolysis of imine using diisobutylaluminium hydride we are using H2O.What is the reason behind this?

We are using H3O+ in the case of preparation of aldehydes in Stephen reaction because the hydrolysis reaction is slow.so this reaction is catalysed by acid(H+).
 
while in case of hydrolysis of imine using diisobutylaluminium hydride we are using H2O for the hydrolysis of the product formed by the reaction of nitriles with diisobutylaluminium hydride,
