U.K. tech startup Synthesia has developed AI-generated avatars that can convey human emotions, bridging the gap between the virtual and real worlds in video production. Backed by Nvidia, Synthesia's "Expressive Avatars" eliminate the need for cameras, microphones, actors, and lengthy edits. The avatars can respond to text inputs representing different emotions, enabling businesses to create engaging content for presentations and training videos. With concerns about potential misuse, Synthesia requires content publishers to sign up as enterprise customers and implements moderation and vetting processes. The company is also actively preventing its platform from being used by hostile actors during elections and is part of the Coalition for Content Provenance and Authenticity.
