Rather than a universal console feature for online voice chat, games will support voice chat on an individual basis, Nintendo told Kotaku.
Games currently confirmed to support voice chat are those with substantial online multiplayer modes, such as Black Ops 2, Assassin's Creed 3 and Mass Effect 3.
Even though the Wii U Gamepad has a built-in microphone, by default it cannot be used for online voice chat in games. Instead, users will have to connect a licensed headset - like the Turtle Beach Ear Force NLa and N11 - to the headphone jack on the Wii U Gamepad.
The Wii U Pro controller, however, does not have a headphone jack, meaning that someone using the smaller non-screen controller would still need to connect a headset to the Wii U Gamepad for in-game voice chat.

Wii U does have bluetooth support, so a wireless headset is possible in the future. However, no Nintendo licensed bluetooth headsets have been announced at this time.
Nintendo also recently detailed the range and wireless capabilities of the Wii U Gamepad.
The Wii U will launch on November 18 in North America and November 30 in Europe with a basic model and Premium bundle.
The basic pack includes a white Wii U console with 8GB of memory, a Wii U gamepad, AC adapter and a HDMI cable.
The Premium set will offer the system in black with 32GB of memory, a copy of Nintendo Land, Wii U sensor bar, a gamepad charging cradle, stands for the gamepad and console and Nintendo Network Premium membership.
