Navigation method and system based on speech command

Abstract

The invention discloses a navigation method and system based on speech command, relating to the technical field of vehicle navigation. Vehicle navigation can be realized through the speech command of an independent speaker by only pressing a key. After the user presses a start key of a one-key control device arranged on a fixed part of the vehicle, terminal equipment establishes voice conversation connection with a VSP server and the system enters into the automatic response state. The VSP server analyzes the speech command of the user by speaker-independent speech recognition technology and sends the analysis result to the terminal equipment, and the terminal equipment starts a navigation module according to the analysis result and displays the obtained analysis result to the user, and the user can complete the operations on the terminal equipment via the speech command. The invention is mainly used for vehicle navigation.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, in particular to a voice command-based navigation method and system. Background technique [0002] With the continuous improvement of people's living standards, vehicles have become an indispensable means of transportation in people's lives. The choice of driving route is one of the important factors that determine travel efficiency or road satisfaction. In order to enable vehicles to serve people better, vehicle navigation is particularly important. [0003] At present, vehicle navigation terminal products can provide users with many functions, such as map query, route planning, navigation and other functions, because the powerful data volume and real-time information that the vehicle navigation terminal products can provide bring people driving travel. Great convenience. [0004] In the prior art, vehicle navigation terminal products, such as GPS navigators, can use manual control ...

Problems solved by technology

[0006] And the voice recognition function in the prior art needs complicated system to realize, as some mobile phones have voice call function, realize through the following process: first need collect the personal voice information of the speaker, set up the telephone book database according to its voice information, personal The phone number and its name or nickname form a fixed link relationship. After calling the callee's name, they will automatically establish a link and call their phone number

This requires the vehicle-mounted equipment to have complex signal processing functions, resulting in increased manufacturing costs, and the storage capacity of the vehicle-mounted equipment is small, so it cannot store more information, that is, there are two problems in the prior art: (1) the phone book needs to be The number link can only be established by calling the name of each person in the network after the information is collected, which makes the user very inconvenient to use. Even if the user only establishes a link to the number of the frequently used contact to reduce the workload, it still exists. The problem of inconvenient use, such as when yo
