Embodiment Construction

[0024] In this embodiment, the pinyin and pinyin tones of the voice prompt information in the electronic map navigation system are stored in a text file in the electronic map navigation system, thereby reducing the storage space occupied by the voice prompt information.

[0025] First of all, in order to facilitate the understanding of the technical solution of this embodiment, the following technical terms appearing in the embodiment are explained:

[0026] Pinyin: According to the composition rules of Mandarin syllables, the initials and finals are quickly combined and added with tones to form a syllable. For example, the pinyin of "Tiananmen" is: tian an men.

[0027] Pinyin tone: four tones of modern Chinese, including: Yinping (the first tone), Yangping (the second tone), the upper tone (the third tone) and the falling tone (the fourth tone), in the present embodiment, the number 1 can be used Represent: Yinping, numeral 2 expresses: Yangping, numeral 3 expresses: Shangsh...

Abstract

The invention provides a method of voice navigation in an electronic map navigation system and a device thereof, belonging to the technical field of navigation. The method comprises the following steps of: memorizing the Pinyin and the Pinyin tone of the character in voice prompt information into a text file in the electronic map navigation system; according to a navigation route generated by theelectronic map navigation system, ensuring the required voice prompt information; and obtaining the Pinyin and the Pinyin tone of the character, which are memorized in the text file and are corresponding to the voice prompt information, and according to the Pinyin and the Pinyin tone of the character, outputting the voice prompt information by means of voice output. By memorizing the Pinyin and the Pinyin tone of the voice prompt information in the electronic map navigation system into the text file, the invention reduces the memory space of the voice prompt information, and leads the electronic map navigation system to be capable of voice indicating and guiding millions of interesting points.

Description

technical field [0001] The invention belongs to the technical field of navigation, in particular to a voice navigation method and device in an electronic map navigation system. Background technique [0002] The car navigation system has the function of providing geographical information and route navigation to the driver. However, because the driver needs to pay attention to the complex traffic conditions around the vehicle during driving, and cannot always pay attention to the display interface of the car navigation system, voice navigation has become a car navigation system. One of the important functions of the navigation system. [0003] Existing voice navigation is to remind the driver of the road conditions ahead through voice. For example, when the vehicle encounters an intersection or turns ahead, the vehicle navigation system prompts the user to turn and other voice prompts, such as "Turn left 100 meters ahead". In this way, the driver can avoid detours. Because th...
