Wii Speak is a microphone accessory for Nintendo's Wii home video game console. Connected to the console via USB, the device can be placed near the video display, which allowed voice chat to be conducted within entire rooms across multiple households.^[2] The device features an LED indicating when the microphone is active.

Wii Speak was announced at Nintendo's 2008 E3 media briefing. It was released on its own, as well as in a bundle alongside Animal Crossing: City Folk, on November 16, 2008 in North America, and on December 5, 2008 in Europe.

The Wii Speak accessory was succeeded by the embedded microphone on the Wii U's GamePad controller. Nevertheless, the Wii Speak hardware is still compatible with the Wii U.

According to Shigeru Miyamoto, the microphone was designed to "clearly capture many different voices being spoken in a room at the same time and convey that over the Internet."^[3] Addressing concerns over background noise due to the placement of the microphone near a television set, Animal Crossing: City Folk producer Katsuya Eguchi stated that the device was designed to filter out video game sound from the audio speakers.^[2] Miyamoto noted at the time that the quality of the noise filtering functionality in the Wii Speak is "very good", which may have contributed to the cost of the device.^[3] An on/off switch was originally planned, but the microphone was ultimately designed to only turn on when a compatible game wants access to it.

In addition to the standalone accessory, the Wii Speak was also made available as a bundle alongside Animal Crossing: City Folk. However, it was not originally Nintendo's intention to release such a bundled product.

At E3 2008, when asked why the device would not be bundled with City Folk, Nintendo senior managing director Shigeru Miyamoto replied that cost was the factor behind the decision, adding that some users may prefer playing the game without a microphone, and that others may want to use Wii Speak who are not interested in buying City Folk.^[3] Despite these initial statements however, Nintendo later revealed that a bundle of the Wii Speak, along with City Folk, would indeed be released.^[4] This bundle was a limited edition, and was released the same day as the standalone products.^[5]
