生成AI(人工知能)を使って自身の声を無断で模倣されたとして、人気声優の津田健次郎さんが短編動画投稿アプリTikTok(ティックトック)運営会社に対し、模倣された声が入った動画の削除を求めた訴訟の判決が30日、東京地裁で言い渡される。生成AIによる声の権利侵害を巡る初の訴訟で、地裁がどのような判断を示すか注目される。

提訴は昨年11月。訴訟では、生成AIによる声の模倣が、著名人が自身の名前や肖像から生じる顧客誘引力を独占できる「パブリシティー権」の侵害や、商品表示の無断使用を禁じる不正競争防止法違反に当たるかどうかが争点となっている。

訴状などによると、2024年7月~25年9月、都市伝説や陰謀論を扱う画像に津田さんの声質を模したナレーションを付けた動画188件が投稿された。津田さんはアニメ「呪術廻戦」の人気キャラクター役などで知られ、動画には「ツダケンの声がする」「声が似ている」などのコメントが相次いだ。

原告側が音声データを分析した結果、津田さんの特徴的な「低く渋みのある声」と類似していた。動画の平均再生回数は1件当たり147万回に及び、投稿者は再生数に応じて月50万~75万円の報酬を得たといい、「ありふれた内容を津田さんの声で読み上げさせることによって商品価値を出した」と訴えている。

これに対して運営会社側は「投稿者は『友人の声を生成AIに学習させた』と述べており、普遍的な男性の声にすぎない」などと反論。提訴後に動画データがアカウントごと削除されたとし、「訴えの利益はない」として請求却下も求めている。

法務省の有識者検討会は8月、声についても写真などの肖像と同様にパブリシティー権の保護対象になるとした指針を公表。権利侵害の可能性がある事例として、著名人の声で別人の曲を歌わせた音源を生成AIで作成し、収益を上げた場合などを示した。同検討会で座長を務めた東京大大学院の田村善之教授(知的財産法)は「判決で声の権利侵害が認められれば、今後、声優らが動画の削除などを要請しやすくなるはずだ」と話した。
