In the past few years, thanks to the advancement of science and technology and the times, the theory and technology of "artificial intelligence" have become more sophisticated, and the field of artificial intelligence applications has also been expanding, covering such areas as smart homes. Following smartphones, voice recognition and voice interaction products have become the battleground for technology giants. Apple, Microsoft, Google, Amazon and other companies have deployed intelligent voice fields. There are also many startup teams and companies that consider voice interaction as The important entrance to the animal network was killed and killed in advance, making the competition in the field of intelligent voice increasingly fierce. After Amazon and Google launched the smart speakers Amazon Echo and Google Home, Apple would not lag behind in the competition, or would launch the smart speaker Siri Hub at this summer's developer conference (WWDC) platform. In fact, this is not the first time that Apple has released smart products. As early as May 2016, it was reported that Apple plans to release smart home devices. Subsequently, some media confirmed that the device has entered the test phase in September 2016. It is reported that Apple’s device will be able to control door locks, lights and curtains through Siri voice. The report also revealed that there were face recognition sensors and built-in cameras in the prototype of the test. In addition to these giants, there are a lot of technology companies that are constantly making efforts in the field of voice recognition and interaction. For example, the Samsung S8 was reported to be equipped with voice assistant Bixby; there is news that Huawei has set up a 100-person engineering team to develop voice assistant functions; Baidu and Tencent also use intelligent voice as an important entry point, such as Tencent has just launched voice assistant “Tencent Jingle Bell†. The voice technology of HKUST has also achieved certain success. In addition, some start-up companies are also actively deploying their own vertical voice products. The reason why voice recognition and interaction is hot is because of its large space for use. In the future, artificial intelligence will certainly become popular as mobile phones, and intelligent voice is the entrance to artificial intelligence. In the future, voice recognition and interaction can be applied in many industries such as transportation, smart home, medical care, banking finance, telecommunications, education, and retail.
