This technology creates realistic facial animations for 3D avatars using audio input.

Nvidia is open-sourcing Audio2Face, its AI-driven tool that creates lifelike facial animations for 3D avatars using audio input. This move allows developers to leverage the tool and its framework to build realistic 3D characters for games and applications.
Audio2Face analyzes a voice’s acoustic properties to generate animation data, which it then applies to a 3D avatar’s facial expressions and lip movements. Nvidia highlights that the tool supports both pre-scripted content and real-time livestreams.
Developers, including Farm51 for Chernobylite 2: Exclusion Zone and the team behind Alien: Rogue Incursion Evolved Edition, have already integrated Audio2Face into their games.
Alongside open-sourcing the Audio2Face models and SDKs, Nvidia is releasing the tool’s training framework, enabling users to customize models for specific applications.

In his first public appearance since his election, Pope Leo XIV laid out the vision for his papacy on Saturday, emphasizing artificial intelligence as a critical global issue while reaffirming the inclusive priorities of his predecessor, Pope Francis. The first American pope also made a personal mark by visiting a sanctuary south of Rome tied to his Augustinian order and Pope Leo XIII, his namesake.Traveling to Genazzano, Leo visited the Madre del Buon Consiglio sanctuary, a 15th-century pilgrimage site managed by Augustinian friars and elevated to a minor basilica by Pope Leo XIII. Addressing the gathered townspeople outside the church, he called the Madonna’s presence both a gift and a responsibility, offering a blessing before departing in a black Volkswagen. On his return to the Vatican, he stopped to pray at Pope Francis’ tomb in St. Mary Major Basilica.Earlier, Leo held his first formal audience with the cardinals who elected him, citing Francis’ 2013 mission statement and pledgi...

On May 2, Reuters reported that Apple is collaborating with Amazon-backed Anthropic on a new AI-powered "vibe-coding" platform, according to Bloomberg News. This platform, an upgraded version of Apple's Xcode, integrates Anthropic's Claude Sonnet AI model to write, edit, and test code for programmers. "Vibe coding" involves AI agents generating code, a trend gaining traction in the AI field. Anthropic declined to comment, and Apple did not immediately respond to Reuters. Apple plans to use the software internally and has not decided on a public release. Previously, Apple announced Swift Assist, an AI coding tool for Xcode slated for 2024, but it was never released due to concerns from engineers about potential delays in app development. AI coding assistants are becoming popular, with OpenAI reportedly in talks to acquire Windsurf, an AI-assisted coding tool, for $3 billion. As competition in generative AI intensifies, Apple is partnering with AI firms and en...
