With a pre-enrolled voiceprint of a specific user (Speaker ID), the receiving angle will follow the specific user, leaving only the specific user's voice retained. Interference from other speakers is discarded, so a far-end listener can easily hear the talker clearly. This technology also integrates Realtek AI noise suppression, making it possible to remove tire noises, traffic noises, rain sounds, etc. These features lead to a highly user-friendly communication environment throughout the vehicle. Realtek will integrate Intelligent Automotive Noise Suppression Technology into the ALC5575 AI audio DSP. This hardware and software total solution for automotive customers enables easy adoption of the new features across platforms. New technology, with enhanced communicative quality, provides a superior user-experience.
