List of languages
From New Leaf onwards, all characters speak in Animalese with some Bebebese, the latter being printed in grey.
Animalese is the default language in the Animal Crossing series. Each letter spoken is stated to synthesize the basic sound of a letter, but the pitch is different depending on the special character or on the personality.
Bebebese is a way animals can speak in all Animal Crossing games. It does not have a vocalization, it instead sounds akin to a typewriter, similar the dialogue sound effects in most other video games. The player uses Bebebese when they catch a fish, insect etc., and the Snowman also uses this language.
Silence is the third of the three 'languages' in the Animal Crossing series. True to its name, the villagers and other animals do not make a sound when talking to the player. However, the town tune still plays while talking to a character.
Silence is completely purged from New Leaf.
Flowerese is the unheard language of flowers. Peppy villagers mention this language while talking to the player sometimes, stating that they can hear the flowers when they water them and that it took such a long time to master Flowerese. The player cannot activate the language Flowerese using the phone in the attic, so it may just be a made up idea created by the peppy villagers.
Raccoonish is a briefly heard ancient language of Raccoons, simply consisting of noises real world raccoons make. Tom Nook, after completing every house upgrade, will express his gratitude by singing a song in Raccoonish passed down by the generations.
