In a recent event held at the 321 Cultural Industry Park in Chengdu, Changhong unveiled the CHiQ TV Q5K, featuring advanced voiceprint recognition technology. This interactive AI-powered television is designed to offer a more personalized and intelligent experience, sparking widespread interest across the industry. With its ability to recognize users through voice and deliver tailored content, the Q5K represents a significant leap forward in smart home technology.
According to an industry expert who tested the product, "In a few years, when deep learning-based AI becomes common on smart TVs, people will truly appreciate the value of the CHiQ TV Q5K. Its voiceprint recognition allows the TV to identify users accurately and quickly recommend their favorite content for the first time."
While many smart TVs today rely only on basic voice control, the CHiQ TV Q5K goes beyond that. It integrates three core technologies: far-field speech, voiceprint recognition, and fuzzy retrieval. These innovations enable the TV to interact naturally with users within a 5-meter range, with a voice recognition accuracy rate of over 97%. The system can learn and adapt over time, making it smarter with each use.
For example, if a user says "Sun Wukong," the built-in AI assistant, Xiaobai, will automatically suggest related content like "Journey to the West" or "Three Battles with the White Bone Demon." This level of intelligence sets the Q5K apart from other AI TVs currently on the market.
Industry experts noted that while many AI TVs focus solely on voice commands, the Q5K uses deep learning and intelligent recognition to create a more logical and accurate user experience. During a comparison test with five other AI TVs, the Q5K stood out for its superior performance and responsiveness.
Behind the Q5K lies Changhong's robust AI technology system. The company’s AI Lab pioneered voiceprint recognition by combining I-vector and PLDA technologies, enabling the TV to create unique voice models for each family member. This allows the TV to distinguish between users and provide personalized content accordingly.
Supported by a powerful data platform, the Q5K’s three key technologies are powered by four core algorithms: semantic understanding, retrieval, recommendation, and data mining. These capabilities allow the TV to interact seamlessly with other smart devices, grow over time, and deliver increasingly personalized experiences.
To support the Q5K, Changhong has integrated a comprehensive ecosystem, including big data, cloud computing, intelligent R&D, manufacturing, and IoT platforms. This full industrial chain ensures that the TV not only performs well but also continues to evolve with user needs.
Experts believe that the success of products like the CHiQ TV Q5K signals a shift in the global home appliance industry. As AI becomes more advanced, with features like learning and intelligent identification, smart homes will become even more intuitive and convenient. Companies like Apple, Gree, and Changhong are leading the way, showing that a strong industrial chain and technological innovation are essential for delivering exceptional user experiences.
