Intelligent terminal, diet searching method of intelligent terminal and unmanned vehicle

Abstract

The invention relates to the technical field of an intelligent terminal, and provides an intelligent terminal, a diet searching method of the intelligent terminal and an unmanned vehicle. When an instruction of a user for expressing diet searching is detected, the intelligent terminal obtains multi-round voice signals input by the user; then, the intuitive intention of the user is recognized according to the multi-round voice signals; further, the navigation record, diet record, diet hobby, diet habit, nearby diet information, hot recommendation information, special promotion information and traveling convenience information relevant to the intuitive intention and at least two of the comprehensive factors in the current time period are obtained according to the intuitive intention; finally, the diet PIO suggestion matched with the intuitive intention is given; the navigation information is provided. By using the invention, the user can conveniently perform voice searching to obtain thediet POI suitable for the user; in addition, the manual screening by the user is not needed; meanwhile, the man-machine interaction process is convenient and natural; the operation is simple; the user experience is greatly improved.

Description

technical field [0001] The present application relates to the technical field of intelligent terminals, in particular to a food search method based on multi-round voice interaction, an intelligent terminal, and an unmanned vehicle. Background technique [0002] Global Positioning System (Global Positioning System, referred to as GPS) is a new generation of satellite navigation and positioning system developed by the United States since the 1970s and fully completed in 1994. It has all-round real-time three-dimensional navigation and positioning capabilities in sea, land and air. The GPS system can be used not only for surveying and navigation, but also for speed measurement and time measurement. Through the accurate positioning of the satellite signal received by GPS, the vehicle's driving route, position, speed, altitude and other information can be known. [0003] Geographical Information System (GIS for short) began to appear in the late 1950s and early 1960s. It is a so...

Problems solved by technology

[0006] At the same time, voice recognition and human-computer voice interaction are also developing in an all-round way. In the operation mode of various existing voice assistant applications (Application; hereinafter referred to as APP), the recording is triggered by pressing the button. After the recording is completed, the machine broadcasts the answer. , when the answer is broadcast, the recording cannot be made

That is to say, the existing voice assistant APPs can only perform half-duplex communication, that is, when the machine broadcasts, the user cannot speak, and when the user speaks, the machine cannot broadcast.

[0007] However, in the prior art, the user cannot use the existing navigation system to directly search for the target restaurant by voice, or the user needs to filter it by himself during the manual search process, and the existing man-machine voice interaction mode is very inconvenient to use , each question and answer requires user intervention, the operation is cumbersome, the human-computer interaction method is also very unnatural, and the user experience is poor
