All Pokémon have distinct cries. These are sounds that are heard when a Pokémon enters battle or uses a vocalizing move (Growl, Roar, etc.). Pokémon within an evolution family will sometimes have similar cries.
This page lists the cries of all Pokémon in the Sage Pokédex.
DEVELOPMENT NOTE: We are going for cries similar to Gens 4/5. Cries should not be longer than approximately 2 seconds.
