Recently, the intelligent hardware offering from Lihua Education, a subsidiary of ShiFang RongHai—the Lihua Education Acoustic Learning Machine—has successfully secured national patent-intensive product certification. This cutting-edge device integrates seven core patents, spanning critical domains such as AI-powered voice training, intelligent conversational systems, and advanced big data analytics. Earlier, the learning machine underwent rigorous aging-adaptability assessments conducted by the China Academy of Information and Communications Technology, achieving the top-tier 'Level 4+ Certification.' Moreover, it has garnered numerous accolades, including the prestigious 'Asia Electronic Information Industry Product Innovation Award.' Its standout feature is its highly customized acoustic AI technology, which excels in accurately identifying regional dialects and indistinct pronunciations, thereby overcoming a major limitation of conventional devices that struggle to 'comprehend the speech of elderly users.' Furthermore, the learning machine boasts a comprehensive trinity teaching closed-loop system, comprising an 'AI Tutor,' an 'AI Practice Partner,' and an 'AI Evaluation System.' This system ensures seamless coverage of the entire acoustic teaching journey, from initiation to mastery.
