The "AI-generated dialogue" is any dialogue generated live during play using artificial intelligence, such as GPT-4. If the developers of a game say that their scripts were co-written or fully written with AI beforehand, this would not count. Mods do not count, only the game as released by the developers.
To make verification easy for whether a game is "critically acclaimed" I will check Wikipedia's section for 2024 games that won awards at awards shows or achieved high scores from Metacritic (i.e. 90+).

3.00It is not looking like there is a critically acclaimed video game this year with AI-generated dialogue.
Satisfactory features a narrator who presents fictively as an AI and whose audio is text-to-speech vocaloid, but the dialogue is not live-generated by AI.
Unless anything changes in the next 15 days, looking likely this'll resolve NO.
@cash I believe Microsoft Flight Sim 2024 also uses some AI-generated voice acting, but not live, just pre-made lines.
The Finals uses live generative AI for their announcer. However, it scored 80 on Metacritic, not 90. Its free-to-play model and lack of a big publisher lock it out of the clout-based events such as The Game Awards.
