How do translation earbuds actually work?

Using the mics, translation earbuds pick up the speaker's voice. High-end translation earbuds use different solutions to separate a voice from background noise. For example, the Soundcore Liberty 5 Pro uses eight microphones, two bone conduction sensors and a specialized AI model to separate voices. Some others use dual or beamforming mics to achieve similar results. After the voice is captured, the next step is audio processing.
