Tell us about this is the world's first voice recognition AI TV @ Changhong Q5K

In daily life, fingerprint recognition and face recognition have begun to be applied, but do you understand voiceprint recognition? Today, this "black technology" was used in Changhong's new TV, and the world's first voiceprint recognition artificial intelligence TV Q5K was officially launched, bringing artificial intelligence television into the 3.0 era.

It is understood that this TV can identify the voice of each member of the family, so that everyone has their own unique personality recommendation, convenient and simple operation, accurate and effective content push, let CHiQ TV Q5K become a family smart partner, effective assistant .

"Guess who I am". When you are blindfolded, the familiar voice behind you is the basis for your response. In the family, both children and mothers say the command "I want to watch TV." At that time, the smart dad understood that the child wanted to watch cartoons, and the mother wanted to follow the latest hits. Voiceprint recognition gives the smart TV a key to future home smart voice assistants, like Jarvis in Iron Man, who can identify who the owner is by voice, who is the guest, and face the instructions of different people. Make a correct response.

Changhong applies the internationally advanced I-vector technology to model voiceprints. At the same time, it uses the cloud computing platform to build a unique voiceprint database for each family member, enabling family members to identify and identify family members quickly and accurately. The rate exceeds 90%.

By identifying different voiceprint features, the identities of the controllers can be located so as to recommend the content suitable for the controller to view. Not only that, when you voice control other content, even if you only say a part of the sentence, or part of the keywords, Changhong Xiaobai can understand what you have expressed and accurately present what you think.

“The use of voiceprint recognition technology on television will redefine the interaction between television and home and users and the experience of scenes, and stimulate greater interest in television for home and users.” Tsinghua University manages the virtual reality and artificial intelligence industry. Wen Lei, a researcher at the Institute, said that voiceprint recognition technology will promote human-computer interaction more convenient and safer to protect home user information, which also gives artificial intelligence TV a new orientation in the Internet of Things era.

At the same time, the CHiQ TV Q5K is also equipped with a new intelligent far-field voice system. Voice-activated words “Changhong Xiaobai” within 5m can be used to respond to calls and turn on the TV instantly to open up a living room. It is understood that CHiQ TV Q5K is the only TV with built-in far-field voice in the industry, and this is more demanding and more advanced than external methods.

TV in the future will become "a thousand people"

It is understood that it is not easy to achieve such an excellent recognition rate. The Changhong voiceprint identification project team encountered many difficulties in the development process. In the early stage of the project, the lack of voiceprint data is one of the major difficulties, and it is impossible to carry out the established model. Effective validation and training. The voiceprint recognition algorithm needs to be able to accurately learn the differences between different speakers under the condition of enough training data. To this end, each member of the project team held the remote control on time every day and kept shouting "Changhong Xiaobai ... I want to see ... I want to see ...", once or twice ... countless times, collecting sound day after day Pattern sample.

With enough data, the design of voiceprint recognition algorithms has become more important. Previously, the technical accumulation of the project team was mainly in the field of image recognition, and there was no experience in the voice-related fields, so the design of the algorithm was particularly difficult. Prof. Wu Jing, the core member of the project team, is in the United States. He is regularly scheduled twice a week through video conferencing and domestic project team members. After three months of hard work, he has finally completed the design of the algorithm, deployment of the server, and successful delivery. .

Self-learning is a great feature of artificial intelligence. With the accumulation of data, the voiceprint recognition model will be updated automatically. Therefore, as the user's use time increases, the recognition rate will become higher and higher and the TV will become more and more aware of you. . Through the combination of voiceprint recognition technology and content retrieval system, CHiQ TV can achieve personalized video content recommendation of “Thousand People”.

Industry's first personal smart TV technology system

In July of last year, Changhong introduced the world's first artificial-smart TV, bringing the global television industry into the era of artificial intelligence. At the same time, Changhong’s intelligent transformation also entered a new phase of artificial intelligence. Since then, the further development of artificial intelligence technology and its application in products and the promotion of iterative upgrades of artificial intelligence appliances have become one of the important tasks of Changhong’s smart strategy implementation.

It is understood that after Changhong introduced the world’s first artificial intelligence TV, color TV industry ushered in new opportunities for development in the era of artificial intelligence. Whether it is the Internet companies or established color TV manufacturers, they are all deploying artificial intelligence, big data, and cloud computing. The Chinese color TV market presents a flourishing scene.

"As the pioneer and leader in the artificial intelligence TV in the world, Changhong insists on providing more and more intelligent products and increasingly personalized services to users in the leading industries of artificial intelligence technology and products to achieve 'product + service + content' 'Maximizing the value'," said Li Wei, general manager of Sichuan Changhong Electric Co., Ltd.

Based on the successful listing of large-scale data operation capabilities and the accumulation of artificial intelligence technology, the company successfully improved and optimized the artificial intelligence TV technology from multiple dimensions including platforms, algorithms, and protocols. The first personal smart TV technology system. This system relies on a powerful data platform and is based on the four major algorithms such as semantic understanding, retrieval, recommendation, and data mining. It is equipped with multiple connection protocols such as device control and basic application management to achieve strong interaction, growth, and reflection. , can be widely coordinated with other smart devices, so as to provide users with more and more intelligent, more and more convenient personalized products and services.

CHiQ TV product manager Chen Keyu introduced that artificial intelligence TV technology system not only includes hardware, algorithms, but also includes data platform and media resources. On the hardware level, Changhong CHiQ adopts integrated array microphone to achieve far field within 5 meters. Voice capture, to achieve such as switching machine, video on demand, timing reminder and other functions. Based on tens of thousands of characters, awards, and other labels, 130,000 semantic keyword terms can be searched by characters, accurate error correction and other fuzzy search, providing users with a more interactive process experience.
