  Algorithm Functions

  • AEC: Eliminates speaker echo for smooth interaction.

  • BF / DPUS: Forms a 60° “voice corridor” to focus on the speaker.

  • NS (Noise Suppression): Filters steady and environmental noise for clear output.

  • AGC: Ensures voice volume remains stable regardless of the speaker’s distance.
