Talking Pokémon

Talking Pokémon are who can speak a human language. The human language itself is not clearly depicted, and all people in the Pokémon world seem to speak one common language, which is always referred to just as human language (however, since Generation IV, it is possible to collect foreign Pokédex entries, and there are NPCs who speak foreign languages). 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.

In, if the player visits Lostlorn Forest, a is disguised as a backpacker who talks to the player before dispelling its illusion and leaving. Also, in Pokéstar Studios, the final film of the Love and Battles Series has a talking, and the Timegate Traveler Series features a talking.

In and, the most notable Pokémon that speaks is.

A at the Aether House tells the player it will curse them when spoken to as well. An in the Konikoni City  also tells the player to "Gu do it!"

In Hey You, Pikachu!, the game centers around using a special device called a PokéHelper that translates certain human-language words into something wild Pikachu can understand. In this game's spiritual successor, Pokémon Channel, various Pokémon appear as hosts and stars of TV shows, with their speech subtitled into the local human language.

Certain Pokémon are also capable of using telepathy, such as the Regigigas in Pokémon Ranger: Shadows of Almia.

It may not be known if all Pokémon, wild or not, are able to understand everyday human speech in the games, as said in 's Pokédex entry, where it describes its ability of human speech comprehension. The Pokédex entries for state that it is able to understand human speech, and it is also said that it can telepathically speak with humans.

In the Mystery Dungeon games and special anime episodes, all Pokémon can talk (minus ). This includes the player, who was transformed into a Pokémon. However, since there are no human characters in the Mystery Dungeon games, it is entirely possible that these Pokémon are not, in fact, speaking human language, but rather their own Pokémon language, which the player can understand as a result of being a Pokémon himself/herself.

In the PokéPark games, all Pokémon can talk. However, like in the Mystery Dungeon games, there are no human characters in the game, suggesting that the Pokémon are simply speaking Pokémon language in between each other, which the player character is able to understand due to being a Pokémon as well. This is further supported by all the Pokémon having their voices from the anime and their speech only appearing in text boxes.

In, the player character, Tim Goodman, is partners with a talking. However, only the player seems to be able to hear Pikachu's talking voice. In addition, the game also features a, which is able to talk via telepathy.

Understanding of human language
Although the Pokémon anime episode The Poké Spokesman states that Pokémon cannot directly understand human speech, this is contradicted by many other episodes before and since in the anime. Moreover, judging, for instance, from in Hatch Me If You Can, they are able to do this immediately after hatching, without having to learn.

The anime generally does not focus on language problems, so as a result, there is some confusion about Pokémon language and the ability of Pokémon to understand humans. Although it is obvious that all Pokémon can understand each other, in Go West Young Meowth once mentions Meowth language, and Jessie in Who's Flying Now? mentions Chimecho language, so it is not clear whether there is a common Pokémon language, or every species has its own.

As far as human language is concerned, in the same episode was shown learning pronunciation, not the language itself, what implies that all Pokémon have innate knowledge of human language, so they can understand human speech, and only have to learn how to pronounce its sounds, or be able to establish telepathic contacts to speak. Despite this, Misty in Whichever Way the Wind Blows once asked to translate her words to other Pokémon, and May taught her  the meaning of the word town in Grass Hysteria!. Therefore, this ability of Pokémon is not well-defined in anime canon.
