Abstract

The invention relates to a voice identification method for position service equipment in the technical field of position services. The method comprises the following steps of receiving voice instructions, and performing characteristic extraction on the voice instructions to acquire voice identification characteristics of the voice instructions; searching standard voice characteristics matched with the voice identification characteristics in a stored voice base; searching corresponding functional commands or interest points in the voice base according to the searched standard voice characteristics matched with the voice identification characteristics; and executing the functional commands, or displaying the interest points. The embodiment of the invention also provides the corresponding position service equipment. The position service equipment provided by the embodiment of the invention can identify voice tasks and solve the driving or walking safety problem of a user caused when the original position service equipment can execute the navigation service by means of single manual operation of the user.

Description

technical field [0001] The invention belongs to the technical field of location services, and in particular relates to a location service device and a voice recognition method for the location service device. Background technique [0002] A location service device refers to a device with location services and related functions. Location service equipment takes navigation equipment as an example. Its working principle is: the navigation equipment determines the location coordinates of a specific location, and matches them with the location coordinates recorded in the electronic map stored by itself, so as to determine the navigation object equipped with the navigation equipment. Accurate location on the electronic map. The navigation device can be a vehicle terminal, a portable navigator, a mobile phone terminal, and the like. Navigation objects can be vehicles, pedestrians, etc. After the user sets the starting point and the destination, the navigation device will calcula...
