Talking Pokémon

Talking Pokémon are Pokémon who can speak human language (what that language is depends on your particular location). While it appears that all Pokémon can understand human speech, very few can communicate with humans except via body language.

There are exceptions to this, however, depending on the version of the Pokémon world being depicted:

Talking Pokémon in video games

In the Pokémon games, Mr. Stone wants to be able to communicate with Pokémon, so he's having Devon Corporation build a translation device for Pokémon. However, the development isn't going so well.

Chatot is a Pokémon mentioned as being able to able to speak the human language through use of its Chatter move.

Copycat's Doduo is able to speak a line of human language when approached.

A Murkrow owned by Team Rocket in G/S/C tells the player the password to the generator room in Mahogany Town

Talking Pokémon in the anime

In the Pokémon anime, very few Pokémon can talk, although many legendary Pokémon can.

• Meowth is the most famous talking Pokémon, and the one that makes the most appearances. His clone, however, cannot speak, as this was not an innate ability, but rather one that was learned through much hard work.
• A Gastly in "The Ghost of Maiden's Peak" has the ability to talk. It is unclear if all Gastly have this ability and chose not to exercise it, or it this particular one was unique. However, no Gastly has spoken before or since, preferring to use other means of communication.
• A giant Tentacruel in the episode Tentacool and Tentacruel spoke through Meowth via telepathy.
• A Lapras in "Holiday Hi-Jynx" has the ability to talk telepathically.
• Mewtwo can talk via telepathy.
• The Lugia in The Power of One also speaks via telepathy.
• A Slowking in The Power of One can also talk.
• Entei can talk in Spell of the Unown. Although this Pokémon is the embodiment of Molly's wishes, so therefore Entei itself probably cannot actually talk.
• Jirachi can talk in Jirachi: Wishmaker.
• Lucario can talk in Lucario and the Mystery of Mew.
• Manaphy can talk in Pokémon Ranger and the Temple of the Sea, although it can only say few words.
• Chatot can repeat human words.
