## Summary

Microsoft filed a patent for an AI system that can alter live video in real time, changing both a speaker’s words and facial expressions. The technology, flagged by patent tracker Patentlyze, uses AI agents to identify and replace or remove specific words or phrases based on user-defined parameters or profiles. It also smooths transitions around edits to maintain audio continuity.

The patent outlines potential uses beyond translation, such as removing filler words like ‘um’ or ‘ah,’ correcting speech impediments, or filtering out offensive or insensitive language. Replacements could even be sourced from internet searches. Critics warn this could deepen personalized media bubbles by allowing viewers to adjust content to their preferences. Microsoft did not respond to a request for comment.

## Key points

- Microsoft’s patented AI edits live video speech and facial expressions in near real time
- System removes or replaces words based on user-set parameters or profiles, with smooth transitions
- Potential uses include translation, error correction, and filtering offensive language or dialects

## Why it matters
