The game's executive producer Steve Lycett reached out to fans on the Sonic Stadium forums and explained that while the Xbox 360 and PlayStation 3 versions will feature online voice chat, the feature is not included on Wii U.
Nintendo confirmed last week that there is no universal voice chat feature on Wii U, and developers will therefore need to implement it individually.
"We don't support voice chat on Wii U for those reasons," Lycett said. "[It's] one of the side effects of being a launch title basically. [We do] support it on PS3 and 360 though!"
Voice chat on Wii U has its own complications even for the games that support it, as users will need to have a Nintendo licensed headset connected to the headphone jack on the Wii U Gamepad.
Sonic & Sega All-Stars Racing is the follow-up to 2010's racing title, featuring nearly 30 characters and lets players drive transforming vehicles.
Developer Sumo Digital recently explained that it had to cut certain fan-favourite franchises from the game, such as Shenmue and Daytona, in order to fit the racer's three-vehicle theme.
Sonic & All-Stars Racing Transformed will be released on November 16 in Europe and November 18 in North America for Xbox 360 and PS3, while a Wii U version will be available when the system launches on November 18 in North America and November 30 in Europe.
A version for Nintendo 3DS and PS Vita is also on the way, and will release on December 11.
