Japan Actors Union introduces guidelines against unauthorized AI voice replication

The Japan Actors Union has introduced new guidelines aimed at stopping the unauthorized use of generative artificial intelligence to replicate voice performances. GamesIndustry.biz, AUTOMATON, and WN Hub all reported that the industry organization released the framework to protect performers from unauthorized voice cloning. [1][3][4]

Under the new framework, developers and creators must obtain prior consent at every stage of using generative artificial intelligence, according to GamesIndustry.biz. This requirement includes securing permission before training artificial intelligence models on an actor's voice performance. Automaton also noted that the guidelines include a strict ban on copying the voices of deceased voice actors. [1][3]

If generative artificial intelligence is used to replicate a voice, GamesIndustry.biz reported that the generated output must be treated as a entirely new performance. This classification requires creators to pay additional royalties or compensation to the affected actors. The union stated that while technology advances, respect for rights and human expression must remain central. [1]

Japanese voice actors perform prominent roles across the global video game and anime industries. Masako Nozawa, a long-time Japanese voice actress, is best known for voicing Son Goku and his male relatives in the Dragon Ball video game and anime franchise since 1986. [5]
