2. Basic information and industry status of iFLYTEK

IFLYTEK Co., Ltd., established in 1999, represents the international advanced level in the core technologies of intelligent voice and artificial intelligence, such as speech synthesis, speech recognition, oral evaluation, language translation, voiceprint recognition, face recognition, natural language processing, etc. It was listed on Shenzhen Stock Exchange in 2008, stock code: 002230.

IFLYTEK is the only "industrialization base of national 863 Program achievements", "key software enterprises in national planning layout" and "national high-tech industrialization demonstration project" with voice technology as the industrialization direction in China. It has been determined as the leader unit of Chinese voice interaction technology standard working group by the former Ministry of information industry, and takes the lead in formulating Chinese voice technology standards. IFLYTEK was selected as one of the first batch of national new generation artificial intelligence open innovation platform, which explicitly relies on the company to build a new generation of intelligent voice National Open Innovation Platform of artificial intelligence. "National intelligent voice high tech industrialization base" and "voice and language information processing National Engineering Laboratory" have successively settled in the company, which is conducive to further gathering resources and improving the leading position of iFLYTEK industry.

With the advent of the mobile Internet era, iFLYTEK took the lead in releasing the world's first iFLYTEK open platform to provide intelligent voice interaction capability of mobile Internet, and continued to upgrade and optimize. Based on this platform, iFLYTEK has successively launched iFLYTEK input method, Migu Lingxi and other demonstration applications, and has worked with its partners to promote various voice applications to mobile phones, automobiles, household appliances, toys and other fields, leading and promoting the transformation of input and interaction mode in the era of mobile Internet.

In 2014, with the arrival of the era of artificial intelligence, iFLYTEK launched the "iFLYTEK Super Brain plan". The goal is to make the machine not only "listen and speak, but also" understand and think ", so as to realize a Chinese cognitive intelligent computing engine, which will lead to intelligent applications in the fields of home furnishing, education, customer service, medical treatment and so on. In 2016, the number of users of iFLYTEK's artificial intelligence open platform doubled with the number of entrepreneurial teams, driving more than one million people to carry out entrepreneurship and innovation activities. IFLYTEK's intelligent platform has been open for several times from 0.46 billion to 0.6 billion in 2018.

Typical research results and industrialization of joint research center

1) Application of "intelligent medical assistant" medical examination robot in auxiliary medical field

In 2017, the "intelligent medical assistant" jointly developed by iFLYTEK and Tsinghua University became the first artificial intelligence robot in China and even in the world to pass the comprehensive written examination of national medical licensing examination with excellent scores exceeding 96 points. In essence, this is a natural language processing system that is particularly good at dealing with medical problems. The algorithm is to find the evidence needed to answer a specific question by calculating the statistical similarity between the words represented by mathematics. A detailed analysis of the test results shows that machines cannot compete with human beings in common sense and ethics. About three months after the results of the "intelligent medical assistant" were announced, the "intelligent medical assistant" officially entered the grass-roots hospitals to provide the general practitioners and residents with artificial intelligence assisted diagnosis and treatment services. At the same time, the "intelligent medical assistant" can quickly generate the electronic medical record and give the diagnosis of the disease according to the dialogue between the doctor and the patient. After seeing the diagnosis of the "intelligent medical assistant", the doctor can check the patient's medical history through the "intelligent medical assistant", and can also query similar cases, clinical guidelines and the drugs used for the symptomatic.

2) Application of natural language processing technology in precise medical text retrieval

Precision medicine is a new medical concept and medical model based on individualized medicine, with the rapid progress of genome sequencing technology and the cross application of bioinformatics and big data science. The diagnosis and treatment of patients are based on the biological characteristics of patients, phenotypes and social characteristics. Through the introduction of medical knowledge base, hierarchical rule optimization and PM document classifier based on deep neural network, the laboratory research group ranked first in two sub tasks of TREC 2018 precision medicine (PM) track in total six indicators, three of which ranked first and two ranked second, ranking first among all the teams.

3) Application of voice quality inspection and analysis technology in customer service center of mobile operators

Call center generates a large number of voice data every day. On the one hand, intelligent voice analysis technology can effectively improve the quality inspection efficiency of call center and improve user satisfaction; on the other hand, it can effectively analyze user feedback information to provide support for product design, marketing analysis and business management of enterprises. After the application of the results in the operator call center, the violation rate of the call center decreased by 87%; and the marketing activities were effectively analyzed, and the project results were highly recognized by the user units and are being promoted nationwide.

4) Application of semantic understanding technology in mobile SMS customer service

The e-channel intelligent service system integrates advanced natural language understanding technology to help users get rid of tedious business codes. Through natural language dialogue, the functions of business consultation, inquiry and processing can be realized. The online application of the system helps users to handle business through natural language, which leads to the increase of business customization; it increases the probability of mobile users using electronic channels by three times, effectively reducing the workload of manual customer service; the introduction of the system also increases the marketing mode of electronic channels, and operators can launch more flexible preferential activities to users through natural language understanding technology. At present, the system has been widely used in more than ten provincial operators in China and achieved good results.
