, it is necessary to which the every words reported are made of different minor sentences in the voice broadcast to navigate in guider, minor sentence
Be it is minimum in Chinese expression there is declarative and independence syntactical unit, be basic sentence；Each minor sentence is by each word
Group composition, in embodiments of the present invention, these phrases are the categories for needing to carry out the induction point of voice prompt according to front to user
Property information determine.
Embodiment one：
Fig. 1 is the flow diagram of phonetic navigation method provided by one embodiment of the present invention, as shown in Figure 1, of the invention
Embodiment includes the following steps：
Step 101, if according to the first position information that mobile equipment is currently located and the second position at induction point place
The distance between information is determined to need voice broadcast, obtained from configuration template file and the corresponding report sentence mould of induction point
Plate；
Step 102, according to the report sentence template generation report sentence to be read；
Step 103, the speech text reported according to sentence generation needs are reported, and voice is carried out according to speech text and is broadcast
Report.
In one embodiment, induction point be by navigation system it is recommended that guidance path in location point, this is lured
Leading a little needs to carry out user voice prompt, pacifies on the turn point, the location point of traffic lights, road in induction point for example, path
Put location point, corresponding location point of danger signal of camera etc., specific name and position of the embodiment of the present invention to induction point
It puts and is not limited.
Phonetic navigation method provided in an embodiment of the present invention when voice broadcast is needed in navigation procedure, passes through and configures
The report sentence template generation report sentence to be read in template file, due to that can update at any time or change configuration template
File, therefore the content of voice broadcast can be changed, improve user experience.
Embodiment two：
Fig. 2 is the flow diagram for the phonetic navigation method that another embodiment of the present invention provides, as shown in Fig. 2, this hair
Bright embodiment includes the following steps：
Step 201, if according to the first position information that mobile equipment is currently located and the second position at induction point place
The distance between information determines to need voice broadcast, determines the type information of induction point, perform step 202.
Step 202, obtained according to the type information of induction point from configuration template file and the corresponding report of induction point
Sentence template performs step 203.
Step 203, determine to report the preset parameter in sentence template according to the type information of induction point and report sentence mould
Variable element in plate performs step 204.
Step 204, whether variable element can determine that according to the type information of induction point, if so, step 205 is performed, if it is not,
Perform step 206.
Step 205, the report sentence to be read is generated according to preset parameter and variable element, performs step 207.
Step 206, the minor sentence reported corresponding to the variable element in sentence is deleted, the report sentence after deletion minor sentence is given birth to
The speech text reported into needs, performs step 207.
Step 207, the speech text reported according to sentence generation needs are reported, and voice is carried out according to speech text and is broadcast
Report.
Embodiment illustrated in fig. 2 is described in detail with reference to Fig. 3, as shown in figure 3, triangular representation movement equipment institute
The position at place, circle represent the position of induction point, which represents that mobile equipment needs are turned right, and arrow direction is for navigation
It unites as the guidance path that Shangdi East Road is driven towards by Shangdi West Road of user's recommendation.
Voice broadcast prompting user need to be carried out when user goes to crossing to turn right.The sentence report content be
Obtained by reading configuration template file, according to the attribute of mobile equipment and the distance and induction point itself of induction point (under
Entitled all the way " six street of Shangdi ", general direction are " Shangdi road direction ") from the sentence of configuration template file reading, generation need to for parsing
The speech text to be reported
In step 201, navigation system needs to get first position information and the induction point that self driving is currently located
The second position information at place, by first position information and the distance of second position acquisition of information therebetween, when judging
When needing to carrying out navigational voice prompts according to induction point, the type information of induction point is determined, in the embodiment of the present invention, to lure
A distance is led to illustrate for the right-hand rotation in crossing.
In step 202, when the type information of induction point is turns right, acquisition is opposite with turning right from configuration template file
The report sentence template answered, in one embodiment, the report sentence template is " front ×× rice is turned right, past into ×× road
×× road direction ".
In step 203, since the type information of induction point is turns right, determine to broadcast by the type information for inducing point
It reports the preset parameter in sentence template and reports the variable element in sentence template, in one embodiment, in above-mentioned steps 202
In shown report sentence template, " front, right-hand rotation, into, toward, direction " for the preset parameter in the report sentence template, " ×
× rice, ×× road, ×× road " is the variable element in the report sentence template, and in one embodiment, variable element is " 500
Rice, six street of Shangdi, Shangdi East Road ".
In step 204, if in actual navigation procedure, although employ report sentence template " front ×× rice is turned right,
Into ×× road, toward ×× road direction ", but in actual guidance path, by the type information for inducing point determine not " it is past ×
This minor sentence of × road direction " needs to delete the minor sentence where variable element at this time.
In step 205, the report sentence to be read is generated according to preset parameter and variable element, as shown in figure 3, according to
Above-mentioned definite preset parameter and variable element, the report sentence to be read is " 500 meters of front is turned right, past into six street of Shangdi
Shangdi West Road direction ".
In step 206, for example, it is desired to will be deleted this minor sentence " toward ×× road direction ", by the report after deletion minor sentence
Sentence generation needs the speech text reported, and raw speech text is, for example,：" front ×× rice is turned right, into ×× road ".
It in step 207, can be by phonetic synthesis (Text To Speech, referred to as TTS) technology by speech text
Sound is converted into, and passes through player and plays out.
Phonetic navigation method provided in an embodiment of the present invention when voice broadcast is needed in navigation procedure, passes through and configures
