What is Siri voice assistant?

Siri is a voice control feature used by Apple on its product iPhone 4S. Siri can turn iPhone 4S into an intelligent robot. Using Siri, users can read text messages, introduce restaurants, ask about the weather, set alarm clocks by voice, etc. through their mobile phones. Siri can support natural language input and can call the system's own applications such as weather forecast, schedule, and search information. It can also continuously learn new sounds and intonations to provide conversational responses. Siri technology comes from the CALO project announced by the U.S. Defense Advanced Research Projects Agency: a digital assistant that allows the military to simplify the handling of complex tasks and has learning, organizational and cognitive capabilities. The civilian version of the software Siri Virtual Personal derived from it assistant. What functions does Siri have? What Siri can do sounds quite ordinary. Users can search for lifestyle information such as restaurants and movie theaters through voice control and text input. They can also directly view relevant reviews and even make direct reservations. , booking tickets; in addition, its location based service capabilities are also quite powerful, and can judge and filter search results based on the user's default home address or location. However, its biggest feature is the human-computer interaction. Not only does it have a very vivid dialogue interface, but the answers it gives to user inquiries are not wrong. Sometimes they even give people a kind of tacit surprise. For example, using If the user's spoken and entered content includes the words "drunk" and "home" (it does not even need to be grammatical, it is quite user-friendly...), Siri will judge that the user is drunk and wants to go home, and will automatically suggest Do you want help calling a taxi? But the only pity is that the software currently only supports English, English, French and German, and the relevant information is also limited to the United States. However, the concept of the entire software can be said to be quite interesting, and it is also free, because it is still It is in the testing phase and the support for Chinese may not be ideal. More language support will be added in the future. Siri has been removed from the App Store. During the Apple launch of iPhone 4S, Apple said that Siri Voice Assistant will become part of iOS. Siri was originally a third-party application that Apple purchased for $200 million last year. Although we can still see this application on the App Store for a long time after the acquisition, it has not been updated for nearly more than a year. It was not until Apple introduced the Siri function at the press conference today that the Siri application was officially removed from the shelves. What you may not have noticed is that Siri's removal from the shelves was carefully arranged: when Siri was first mentioned at the Apple conference, the application could still be easily found on the App Store. But after the conference, the application could no longer be found. It seems that the Siri application was removed from the shelves at the end of the conference. Why was it removed from the shelves? This may be because Apple is worried that if third-party applications can realize the functions of iPhone 4S, it will affect the desire of existing iPhone users to buy new iPhones, thus affecting sales.
