With the growing integration of artificial intelligence into consumer electronics, once-mysterious technologies are now becoming more accessible and familiar. When SIRI first launched, it sparked a wave of excitement around the idea of "technology reshaping life." Later, concepts like "big data + internet" became mainstream, and now, voice-activated assistants have become as common as the neighborhood store. But what about the "ghosts" of far-field voice technology that keep popping up in smart TVs and network set-top boxes?
Smart far-field voice is a game-changer in user experience, leveraging AI-powered voice search to make interactions smoother. Users who have tried Bluetooth voice remotes know that they need to press a button on the remote to activate voice commands. However, with far-field voice technology, this step is eliminated—you can simply sit on your sofa and speak naturally. Currently, the system works effectively within a 5-meter range, providing quick feedback.
In the realm of smart far-field voice interaction, the key challenge lies in reliably waking up the device in a noisy living room environment. This requires a seamless combination of front-end hardware and back-end software. On the front end, microphone arrays capture sound, while advanced techniques like sound source localization and adaptive beamforming enhance speech clarity. These methods help reduce background noise, echoes, and reverberation. Paired with AI algorithms, the system creates a powerful recognition engine, enabling natural, long-distance communication between users and their smart devices.
Currently, leading Chinese TV manufacturers like TCL and Konka have adopted far-field voice technology in their products, such as TCL's "small T" and Konka's A1 series. Internet TV brand Storm TV has also introduced its own solution—Storm Ears—connecting smart TVs and set-top boxes through thousands of devices. As this trend continues, the success of far-field voice technology on smart TVs may soon extend to smart boxes as well.
The current focus in voice solutions is mainly on companies like HKUST and Conexant. The fusion of far-field voice, AI, and voice technology providers is expected to drive a new wave of growth in the smart TV and set-top box industries.
