Video is one of the fastest-growing online services offered to consumers. A growing number of people today are participating in video creation and consumption in the digital economy. We study whether and how AI-generated voice affects users’ routine efforts and creative efforts in online video creation. Using a unique dataset of 2,617 creators and 273,244 videos collected from TikTok over a 25-week period, we first exploit deep learning models to detect the adoption of AI-generated voice from massive video data. Then we estimate its treatment effect on creators and viewers using a difference-in-differences model coupled with propensity score matching. We find that AI-generated voice increases creators’ routine effort and creative effort in the short term. While it has a long-lasting effect on improving the efficiency of video creation, AI-generated voice cannot consistently motivate creators to include more information in videos, and might even be detrimental to their creative effort in the long term. Our study provides the first empirical evidence on how AI tools reshape video content creation patterns on online platforms, which carries important managerial implications for individual creators, platforms, and policymakers in the digital economy.
