[0026] 建立常用字TTS数据库,并将所述常用字TTS数据库存储在所述导航设备的内存中。 [0026] TTS establish a common word database, and the database is stored TTS common word memory in the navigation apparatus.

[0027] 本发明实施例导航方法中,需要进行语音输出的文字信息,可以是对语句进行语言学分析,得到的分析后的文字信息。 Example Navigation embodiment [0027] The method of the present invention, the need for character information output from the speech, statements may be a linguistic analysis of the text information obtained by the analysis. 语言学分析例如同音字、同音词的判断、句子的分词、句式分析等。 Linguistic Analysis e.g. homophones, the homophone is determined, the sub-word in the sentence, sentence analysis. 具体可以參考现有技术得以理解,在此不作赘述。 Specific reference to the prior art can be appreciated, this will not be repeated herein.

[0028] 具体而言,所述建立常用字TTS数据库的方式,可以包括: [0028] Specifically, the establishment of a database of common words TTS manner, comprising:

[0029] 将现代汉语常用字表记载的常用字以及次常用字作为所述常用字,建立常用字TTS数据库。 [0029] A common word table described in Modern Chinese characters commonly used words as well as the secondary common word used to establish a common word TTS database.

[0030] 示例性的,目前《现代汉语常用字表》中收录常用字2500个,以及次常用字1000个。 [0030] Examples of the current "modern Chinese characters commonly used form" collection of commonly used words in 2500, and once commonly used word 1000.

[0031] 或者,可以替换的,所述建立常用字TTS数据库的方式,可以包括: [0031] Alternatively, alternatively, the establishment of common words database TTS manner, comprising:

[0032] 对导航语音提示用字中包含的文字作为所述常用字,建立常用字TTS数据库。 [0032] The voice guidance contained in the word text used as the commonly used word, establishment of common word TTS database. [0033] 示例性的,导航语音提示用字如“请向左前方行驶”、“请直行”,等等,则对导航语音提示用字中包含的文字作为常用字,建立常用字TTS数据库,便于导航语音提示时,提高语音合成速度,改善用户体验。 [0033] An exemplary, with the word voice guidance such as "Please travel left front", "Please go straight", and the like, then the text with the word voice guidance included as commonly used words, the establishment of a common word TTS database, when ease of navigation voice prompts, improving the speed of speech synthesis, improve the user experience.

[0034] 或者,可以替换的,所述建立常用字TTS数据库的方式,可以包括: [0034] Alternatively, alternatively, the establishment of common words database TTS manner, comprising:

[0035] 对电子地图数据库中道路名称包含的文字按照出现频率进行排序。 [0035] digital map database for text contained road names sorted by frequency of occurrence.

[0036] 以及,将出现频率高的文字作为所述常用字,建立常用字TTS数据库。 [0036] and the high frequency of the text appears as a common word, establishment of common word TTS database.

[0037] 其中,所述电子地图数据库包括国家电子地图数据库、行政省电子地图数据库或者行政市电子地图数据库中的ー种。 [0037] wherein the electronic map database includes national electronic map database, the provincial executive or administrative electronic map database City electronic map database ー species.

[0038] 示例性的,统计对电子地图数据库中道路名称单字出现的频度,按频度的高低排序,把频度高的单字对应的语音库或规则优先加载到内存。 [0038] An exemplary, statistics on the frequency of electronic road map database name word appears, sorted according to the level of frequency, the high frequency words or speech database corresponding priority rules loaded into memory. 道路名称如深南大道,位置名称如世界公园。 Road names such as Shennan Avenue, the location name such as the World Park.

[0039] 所述规则,是在进行语音识别过程中对字词句进行判断的规则,例如同音字、同音词的判断、句子的分词、句式及语音提示的判断等。 [0039] The rule is a rule during the speech recognition process is judged to explore issues such homophones, the homophone is determined, the sub-word in the sentence, the sentence and the voice prompt judgment.

[0040] 具体的,将导航设备内一定范围的电子地图数据库中所有道路名称进行统计,根据出现次数将出现过的汉字进行排序,如出现次数最多1000〜2000个汉字连同语音提示用字,语音提示用字例如“前方右转,请注意驾驶”,对应的TTS数据库预加载至内存中。 [0040] Specifically, the navigation device within a range of electronic map database statistics for all road names, sorted according to the number of occurrences of the characters appeared, such as the number of occurrences of up to 1000~2000 characters along with voice prompts with the word, voice presentation word such as "turn right ahead, driving note", corresponding TTS database preloaded into memory.

[0041] 上述一定范围,可以是整个国家,也可以是ー个省、一个地级市的范围,可根据导航设备的性能、内置电子地图数据的范围自动或手动的进行设定。 [0041] The range may be the whole country, it can be ー provinces, a city level ranges, according to the performance of the navigation device, digital map data is a range built automatic or manual setting.

[0042] 例如,导航设备内存空间较小,则不推荐采取全国范围内的道路名称进行统计排序。 [0042] For example, a smaller memory space navigation equipment is not recommended to take the road name nationwide statistics sorted. 又例如,用户的导航设备内只有A省内的电子地图数据,用户也极少需要出省,那么也就没必要采取全国范围,较大范围内的统计排序也应该对应选取较大区间的汉字进行预加载(例如全国范围则将前2000个汉字对应的TTS数据库加载至内存,地级市范围则将前1500个汉字对应的TTS数据库加载至内存即可)。 As another example, the user's navigation equipment only within the province of A digital map data, users rarely need out of the province, it is also no need to take the country, ordering a wide range of statistics should correspond to select a larger range of characters preloaded (e.g. 2000 characters before then the country corresponding to TTS loaded into memory database, then the former level city range 1500 corresponding to the characters loaded into the database memory can TTS).

[0043] 上述统计排序可以在语音服务的初次手动设置或手动更改设置时进行,也可以在导航设备识别出当前行政区划的改变时进行。 The first time you perform a manual [0043] The statistics can be sorted in voice services set or change the settings manually, can also be carried out when the navigation device recognizes change the current administrative division.

[0044] 导航设备后续自动采用前一次的排序结果进行预加载,例如用户从A省自驾进入B省,这时导航设备可以自动识别出当前行政区划的改变,从而采用B省范围内的道路名称进行统计排序,这样更能够避免准备进行TTS语音合成的汉字在预加载的内存中找不到从而需要去存储卡中TTS数据库读取数据。 [0044] Automatic navigation apparatus using a subsequent previous ranking result preloading, for example the user enters the province from Province A car B, then the navigation device may automatically recognize the change of the current administrative divisions, so that the road name using province range B statistical sorting, which is more able to avoid preparing for TTS speech synthesis can not find the characters thus need to store card data in the database read TTS preloaded memory.

[0045] 如图2所示,对应上述实施例的导航方法,本发明实施例提供ー种导航设备,包括: [0045] 2, the navigation method corresponding to the above-described embodiments, embodiments provide a navigation device according to the present invention ー species, comprising:

[0046] 查询单元21,用于对需要进行语音输出的文字信息,优先在导航设备的内存中的常用字文本到语音TTS数据库中查询匹配的文本信息。 [0046] 21, the need for voice output character information query unit, preferentially a common word text memory of the navigation device to the TTS voice database query matching text information.

[0047] 输出单元22,用于当所述查询単元查询有匹配结果时,将所述匹配的文本信息转化成语音信息并进行输出。 [0047] The output unit 22, for radiolabeling the query element when the query matching results, matching the text information into voice information and outputs.

[0048] 查询单元21,还用于当没有匹配结果时,在所述导航设备的存储卡中的TTS数据库中查询匹配的文本信息。 [0048] The query unit 21 is further configured to, when there is no matching result, the TTS database in the memory card in the navigation device query text information match.

[0049] 由上述本发明提供的技术方案可以看出,进行语音提示时,优先查询导航设备内存中常用字TTS数据库,避免频繁到存储卡的TTS数据库读文件,从而提高语音合成速度,减少对存储卡的反复调取和释放的过程,降低了对存储卡的损耗。 When [0049] provided by the embodiment of the present invention can be seen art, voice prompts, priority search word commonly used in the navigation apparatus TTS database memory, to avoid frequent memory card read the database files TTS, speech synthesis thereby improving the speed, to reduce the repeating retrieval of the memory card and the release process, reducing the loss of the memory card.

[0050] 本发明实施例的导航设备,还可以包括:建立単元,用于建立常用字TTS数据库,并将所述常用字TTS数据库存储在所述导航设备的内存中。 [0050] Example embodiments of the present invention, the navigation apparatus may further comprise: establishing radiolabeling element for establishing a common word TTS database, and the database TTS common word stored in memory of the navigation device.

[0051] 具体而言,所述建立単元,具体用于将现代汉语常用字表记载的常用字以及次常用字作为所述常用字,建立常用字TTS数据库。 [0051] Specifically, the establishing element radiolabeling, particularly for modern Chinese characters commonly used word table described in commonly used words as well as the secondary common word, establishment of common word TTS database.
