Voice communication with the machine, let the machine understand what you say, this is what people have long dreamed of. The voice recognition technology is the high technology that allows the machine to convert the voice signal into the corresponding text or command through the process of recognition and understanding.
In 1952, Davis and others at the Bell Institute succeeded in researching the world's first experimental system that can recognize the pronunciation of 10 English numbers.
In 1960, Denes and others in the United Kingdom successfully studied the first computer speech recognition system.
Large-scale speech recognition research has made substantial progress in the recognition of small vocabulary and isolated words after entering the 1970s.
After entering the 1980s, the focus of recognition research gradually turned to large vocabulary, non-specific continuous speech. Significant changes have also taken place in the research ideas, that is, the traditional technical ideas based on standard template matching have begun to turn to those based on statistical models (HMM). In addition, the technical idea of introducing neural network technology into the speech recognition problem is again proposed.
After entering the 1990s, there was no major breakthrough in the system framework of speech recognition. However, great progress has been made in the application and commercialization of speech recognition technology.
Basic course of Chinese speech recognition
Research on speech recognition in China began in 1958, when the Institute of Acoustics of the Chinese Academy of Sciences used electronic tube circuits to recognize 10 vowels. It was not until 1973 that the Institute of Acoustics of the Chinese Academy of Sciences started computer speech recognition. Due to the limitations of the conditions at the time, the research work of speech recognition in China has been in a slow development stage.
After entering the 1980s, with the gradual popularization and application of computer application technology in China and the further development of digital signal technology, many domestic units have the basic conditions to study voice technology. At the same time, international speech recognition technology has become a research hotspot again after years of silence, and has developed rapidly. In this form, many domestic units have invested in this research work.
In the past two decades, speech recognition technology has made significant progress. It has moved from the laboratory to the market, and is gradually improving.
Based on this, the programmer inn - house developed multiple angles corporate capital value, R & D and innovation, industry influence and so on departure from, as well as voice recognition on the domestic market analysis and research, assessment of the current manufacturers in the country in addition to BAT, Outside the 2020 speech recognition TOP20 companies.
