OpenAI’s Sora 2 lets users insert themselves into AI videos with sound

OpenAI has introduced Sora 2, its latest video-synthesis AI model that can produce videos in various styles with synchronized dialogue and sound effects, marking a first for the company. Users can now insert themselves into AI-generated videos using OpenAI's new iOS social app through "cameos." The new model was demonstrated in a video featuring a lifelike version of OpenAI CEO Sam Altman speaking in a slightly artificial voice against imaginative backgrounds. Sora 2 can generate realistic background soundscapes, speech, and sound effects. This release follows Google's Veo 3 and Alibaba's Wan 2.5 in incorporating synchronized audio into video-synthesis models.
