Microsoft's New REALTIME AI Face Animator - Make Anyone Say Anything

Science & Technology

Introduction

Introduction

There's good news and there's bad news. Microsoft has just dropped an exciting new article titled "Vasa 1: Lifelike Audio-Driven Talking Faces Generated in Real Time." This new AI technology takes a single image and any audio clip to animate the face in real-time. Before diving into the details, let's explore some examples.

Introducing Vasa

We introduce Vasa, a framework for generating lifelike talking faces with appealing visual effective skills. Given a single static image and a speech audio clip, our model can produce not just synchronized lip movements but also a large spectrum of facial nuances and natural head motions. These attributes contribute to an authentic and lively perception.

Core Innovations

The key innovations include:

  • A holistic facial dynamics and head movement generation model that works in a face latent space.
  • The development of an expressive and disentangled face latent space using videos.

These innovations contribute to a more pleasant user experience and better business metrics since users dislike interruptions and broken experiences.

Evolving AI Technology

The progress in creating talking faces and avatars is impressive. A year ago, avatars looked robotic, but now they are incredibly realistic.

Microsoft’s Model

Microsoft’s model significantly outperforms previous methods. It delivers high video quality with realistic expressions and supports online generation of 512x512 videos at up to 40 frames per second, with negligible latency. This paves the way for real-time engagements with lifelike avatars.

Comparison with Alibaba's Emo Portrait Live

Microsoft is not alone; Alibaba recently released an AI called Emo Portrait Live, which also animates faces using a single photo and audio.

Customization Capabilities

Microsoft’s tool allows extensive customization:

  • Eye Gaze: Change the direction of the eyes.
  • Head Distance: Adjust the apparent distance of the head from the viewer.
  • Emotions: Customize facial expressions like happiness, anger, or surprise.

Even paintings can be animated, and the AI handles non-English speech and singing, which is impressive considering the training data primarily included English speech.

Practical Implications

With such technology, one can easily make any face say anything in real-time, raising concerns about its misuse for deep fakes or scamming.

Real-Time Demo

There's even a real-time demo where you can upload or record audio or use text-to-speech.

Conclusion: The Bad News

Despite this promising technology, Microsoft announces they have no plans to release an API, demo, or implementation details until they are certain the technology will be used responsibly. The same goes for Alibaba's tool.

This raises questions about how this technology could impact evidence in court or be misused, but for now, it remains inaccessible to the public.
