Bandai Namco has acknowledged issues with the voice acting in "Naruto x Boruto: Ultimate Ninja Storm Connections" after receiving complaints from players and voice actors. Concerns were raised when Naruto's voice changed mid-sentence in the game, leading to questions about the use of AI-generated voice overs. Voice actors Maile Flanagan and Michael Schwalbe expressed doubts about the final recording quality, speculating that their performances were edited without context or possibly altered with AI technology.

Although AI detection tools indicated potential AI usage in the game's voice acting, this has not been confirmed. The topic of AI in voice acting is contentious, with SAG-AFTRA considering a strike over the use of AI in video game voice work. Bandai Namco has promised to patch the questionable voice lines soon and stated that the issues were not due to AI but rather inconsistencies in the editing process.

Aside from the voice acting concerns, "Naruto x Boruto: Ultimate Ninja Storm Connections" has been criticized for offering little beyond flashy graphics in comparison to earlier entries in the series that featured the same fighting system and more compelling single-player stories.

Gamers and voice actors alike are awaiting the promised update from Bandai Namco, which has yet to set a date for the voiceover patch for "Naruto x Boruto: Ultimate Ninja Storm Connections." Meanwhile, the controversy underscores the ongoing debate regarding the ethical use of AI in the entertainment industry, particularly in voice acting for video games.
