Artificial intelligence is becoming more and more "hot". With the current intelligent voice technology, the machine can't fully understand the natural language. The scene of understanding the "out-of-string sound" only exists in science fiction works. But this is changing -
The latest domestic intelligent speech technology results show that the machine can achieve speech conversion text, multi-language simultaneous translation, and even imitate someone's voice line speech with high accuracy.
Accurate recognition of simultaneous translation
At the venue of thousands of people, many guests had nearly three hours of speech exchanges, and there were no stenographers in the whole process. The contents of the speeches could be turned into text on the big screen in real time.
The reporter saw at the annual conference of the University of Science and Technology on the 23rd that in addition to the mistakes of individual names in the speeches and the redundant words in the speaker's spoken language, most of the speeches were organized very accurately and synchronized. Translation into English, Japanese, Korean and other languages.
In the display of the intelligent in-vehicle system, in the face of the driver's arbitrary interruption and random interjection, the in-vehicle system can quickly understand the driver's intention through the context of the context, and even the minimally simple instructions for deliberate "difficulty" can be quickly Understand the "out of the string", navigation, listening to songs, group tickets are not in the words.
According to reports, these are based on deep neural network speech recognition technology. Speech recognition technology, simply puts the computer to "understand" the human voice, extracting the text information contained in the voice. This technology plays an important role in the intelligent computer system, which is equivalent to putting an "ear" on the computer to enable human-computer communication and interaction. At present, the accuracy of speech recognition can reach 97%.
"With the advent of the Internet of Everything, human-computer interaction based on voice and keyboard touch is gradually becoming a necessity. In the next 5 to 10 years, artificial intelligence will become a necessity for our lives like water and electricity, profoundly changing our The world," said Liu Qingfeng, chairman of the board of directors of Science and Technology.
Speech synthesis "to fake the truth"
Smart robots can be heard that speech synthesis technology is "letting machines speak like humans." It is a cutting-edge technology for information processing in many disciplines such as acoustics, linguistics, digital signal processing, and computer science.
Li Deyi, an academician of the Chinese Academy of Engineering and chairman of the China Artificial Intelligence Society, said that in the field of artificial intelligence, dialogue is the most direct and convenient way of interaction. Dialogue intelligence is an essential skill for almost all service robots .
The technique of letting the robot "speak" is not new. It can be used on electronic calendars and calculators, but it is not easy to speak fluently and vocally like people.
The reporter used the mobile phone to test the speech synthesis software developed by Keda Xunfei on the spot, and found that the speech synthesis function can not only convert the text information into audible sound information, but also can collect the voice characteristics of a person into the voice library, and then use it very short. The time to read the text with the voice characteristics of the imitated person, there is indeed a false effect. In the future, people's voices may also be used for "stolen."
At present, China has realized 5 to 8 meters of far-field recognition, multi-round interactive dialogue, free wake-up words exchange, and communication interruption at any time. The human-computer interaction is more and more smooth and natural.
"Not only has Chinese speech synthesis technology made a breakthrough, in this year's global speech synthesis competition, the speech synthesis technology of Keda Xunfei can express English stories with great enthusiasm and performance in multi-language testing." Liu Qingfeng said.
Artificial intelligence changes the world
Nowadays, artificial intelligence based on intelligent voice technology has shown great potential in many fields such as mobile phones, education, furniture, automobiles, medical services and service robots.
In January of this year, Japan proposed the development plan for a super-intelligent society; in October, the United States introduced an artificial intelligence industry plan. Developed countries are already thinking about the risks that artificial intelligence may bring, how artificial intelligence can achieve the integration of people and machines, and laws related to artificial intelligence.
In April of this year, China’s Ministry of Industry and Information Technology and a number of domestic enterprises jointly issued the “Artificial Intelligence Shenzhen Declarationâ€. The declaration not only emphasizes that artificial intelligence must be a source of technological innovation, artificial intelligence must have standards, but also emphasizes active exploration of artificial intelligence technology. Develop a balance between ethics and morality, and let artificial intelligence better serve humanity.
Li Zhengmao, vice president of China Mobile Communications Corporation, said that robots based on artificial intelligence technology are likely to become the next generation of electrical products beyond the global population, and the future robot market may exceed 10 billion.
For artificial intelligence technology, one side is a beautiful imagination, and the other side is a cautious concern. The famous scientist Hawking believes that artificial intelligence will replace or even enslave human beings in the future. The recent popular films such as "Western World" and "Black Mirror" also express concerns about artificial intelligence and future technology. Is the robot threatening human beings?
The future is changing, no one can predict the future, and the pace of artificial intelligence technology will not slow down.
