Which Pokémon game was bundled with a microphone for voice commands on Nintendo 64? Hey You, Pikachu! is the answer.

Hey You, Pikachu! is a Nintendo 64 virtual-pet game that shipped with Nintendo’s Voice Recognition Unit and microphone. Players speak selected commands to Pikachu, directing it during activities, exploration, and minigames. The game’s central appeal was interacting with Pikachu as a companion rather than battling through a traditional Pokémon adventure.

The Voice Recognition Unit did not understand unlimited natural speech. Its software relied on a limited vocabulary, described as a 256-word database, so players had to use recognizable commands and clear pronunciation. Pikachu’s responses could also vary depending on its mood and relationship with the player.

The game was developed by Ambrella and released in Japan in 1998, with a North American release in 2000. It is often confused with Pokémon Stadium, which also appeared on Nintendo 64 but focused on battles and minigames. Hey You, Pikachu! is especially notable because it required the microphone accessory for its intended gameplay.
