## Summary

Microsoft filed a patent application on April 29, 2025, describing an AI system that edits a speaker's words in live video and redraws lip movements to match the changed audio. The system can replace filler words, stutters, mispronunciations, offensive terms, and colloquialisms, or substitute translations based on viewer profiles. Microsoft has not said whether it plans to develop the technology, and the patent examiner rejected the submitted claims on July 29, 2026.
