Animalese

Animalese is the default language the NPCs in speak. Each letter spoken is stated to synthesize the basic sound of a letter, leading to mispronounciation of some words. (i.e. "Animal Crossing" would be pronounced "Ah-n-ih-m-ah-l c-r-o-s-s-ih-n-g"). When villagers say numbers, they will talk rather clearly, like when the player is typing a letter. The name of the player and the name of the town can be clearly discerned as well, although they may also be mispronounced depending on the way each letter of the word is said in Animalese. Laughing and similar sounds are also discernible. However, much of Animalese is completely unintelligible.

Different personalities (such as Cranky or Snooty), animals that work in the town (ex: Pelly, Tom Nook) and 1-day visitors to the town (Gracie, Wendell, etc.) will have different pitches to Animalese. Different characters will have higher or lower voices. If you speed up the text, the Animalese also speeds up, sounding more highpitched. Also, happy, sad, or angry villagers will have a different pitch to Animalese. Also, the sound of Animalese differs slightly in each game.

Bebebese or Silence can be spoken as an alternate language in the options.
