In multi-device collaborative recording scenarios, the frequency band isolation design of privacy guard cover is the core technical approach to avoid signal cross-interference.

Desensitizing a single sentence of speech may lead to semantic breaks, while desensitization algorithms that incorporate dialogue history can improve data usability.

In the design process, this situation should be avoided as much as possible. By breaking the symmetry, the reflection of sound inside the protective cover becomes more complex and random, reducing the concentration of echoes.

Using efficient network protocols can reduce data overhead during network transmission and improve data transmission efficiency.

As a physical-level protection device, Privacy Guard Cover, with its simplicity, reliability, and efficiency, has become the "first line of defense" for an increasing number of users seeking to safeguard their personal privacy.

The AI ​​Voice Recorder, with its core features of "one-click recording + dual-marker microphone + intelligent noise reduction," is redefining the professional-grade voice capture experience. Its amazing noise reduction effect is not only reflected in the
