Problems solved by technology

However, since the voice library is built in the system, users cannot directly customize it
When the user is dissatisfied with the broadcast effect, he cannot modify a certain prompt voice alone
The existing navigation system will give the user detailed road information voice prompts during the guidance process. The navigation system synthesizes the voice through the TTS engine. Since the voice library is built into the system before the navigation leaves the factory, the user cannot freely replace the prompt voice

Embodiment 1

[0035] This embodiment provides a navigation system user voice customization method, which is characterized in that: the hardware of the navigation system user voice customization method involves a positioning module, a route calculation module, a guidance module, a TTS speech synthesis module, and a decoding module;

[0036] The positioning module obtains the position information through the GPS module of the hardware during the driving process of the car; most of the communication adopts the NMEA-0183 protocol, and the message contains the coordinate information required for positioning; the module needs to parse the message first, and after obtaining the position coordinates After that, the trajectory is corrected through the map matching algorithm, and finally the more accurate position coordinates are obtained;

[0037] The road calculation module provides the function of finding the route with the shortest driving time for the vehicle from the departure point to the desti...

Abstract

A navigation system user voice custom method comprises hardware of a location module, a calculation way module, a guide module, a target tracking system (TTS) voice synthesis module and a decoding module. When the guide module generates character strings in buffer memory, voice in the buffer memory can be played directly. Before voice is synthesized, a system can compare character strings of guide information with all character strings in the buffer memory to play voice. A custom voice file is of a structure identical with a structure of a voice cache file, the custom voice file is formed by an index and a data portion, and the voice cache file is also formed by an index and a data portion. Personal computer (PC) terminal software can firstly read the voice cache file, the custom voice file is added to navigation equipment, and a navigation system starts the custom voice function. A voice recording tool can collect and store voice into a data file, and the voice is stored is guided into the navigation system to serve as a custom voice library. The navigation system user voice custom method has the advantages of using the voice custom function, correcting error of synthetizing voice with a TTS engine, adding custom capacity of the navigation system and quickening real time performance of voice prompt.

Description

technical field [0001] The invention relates to the field of navigation systems, in particular to a voice customization method for users of the navigation system. Background technique [0002] With the increasing complexity of urban road networks and the increasing number of vehicles, car navigation systems have been widely used. The driver can still drive freely in complex road conditions. Car navigation system is a typical embedded device, which is limited by size, cost, power consumption and application occasions. [0003] With the development of embedded technology, car navigation system is developing toward intelligence and humanization. The real-time voice guidance function has been widely used in navigation terminals. Users can obtain guidance voice prompts in real time, and can conveniently obtain more map prompt information without looking at the map during driving. Voice guidance makes the human-computer interaction more humanized, and at the same time ensures ...
