Background noise from participants eating or chewing during video calls has become a widespread nuisance, disrupting meetings and reducing professionalism. While general noise-cancellation tools exist, they often fail to specifically address chewing sounds, which have distinct acoustic patterns. This problem affects remote workers, educators, and students who rely on video conferencing daily.

How the Idea Works

One way to tackle this issue could involve a software layer that uses machine learning to detect and mute chewing sounds in real time. The system would continuously analyze audio input, identify chewing using a trained model, and either temporarily mute the participant or notify them to mute manually. Optionally, it could expand to detect other disruptive noises like keyboard typing or loud breathing.

• For users: Fewer distractions and more professional meetings.
• For platforms: A niche feature to differentiate their products.
• For developers: Potential monetization through licensing or direct integration.

Execution Strategy

A lightweight desktop app that analyzes recorded meetings and provides a "chewing noise score" could serve as an MVP to test demand and model accuracy. If successful, a real-time version with adjustable sensitivity could be developed. Eventually, partnering with video conferencing platforms for native integration might be feasible.

Key assumptions to validate include whether chewing sounds are distinguishable from speech, whether users want automated muting, and if real-time processing is feasible without lag.

Comparison with Existing Solutions

Unlike general noise suppressors like Krisp or NVIDIA RTX Voice, this idea specifically targets chewing sounds, offering more precise detection. Zoom’s built-in noise cancellation is generic, often letting chewing slip through, whereas this approach could provide higher accuracy for a common annoyance.

Potential expansions could include visual feedback when muted for chewing, custom noise profiles, or host controls for meeting-wide settings.
