Embodiment
The phonetic navigation method and the device that the embodiment of the present invention are provided below in conjunction with accompanying drawing are described in detail.
In the voice broadcast navigating at guider, need every words reporting to be made up of different minor sentences, minor sentence is the syntactical unit with statement property and independence minimum in Chinese expression, is basic sentence; Each minor sentence is made up of each phrase, in embodiments of the present invention, these phrases be according to front need to user carry out voice message induction point attribute information determine.
Embodiment mono-:
The schematic flow sheet of the phonetic navigation method that Fig. 1 provides for one embodiment of the invention, as shown in Figure 1, the embodiment of the present invention comprises the steps:
Step 101 if determine and need voice broadcast according to the distance between the primary importance information at the current place of mobile device and the second place information at induction point place, is obtained and induces a little corresponding report statement template from configuration template file;
Step 102, generates the report statement that will read according to reporting statement template;
Step 103, generates according to reporting statement the speech text that needs report, and carries out voice broadcast according to speech text.
In one embodiment, induction point is the location point in the guidance path of having recommended by navigational system, this induction point need to carry out voice message to user, induction point is for example for settling location point corresponding to location point, the hazard identification of camera etc. on the location points of turn round point, traffic lights in path, road, the embodiment of the present invention does not limit concrete title and the position of induction point.
The embodiment of the present invention provide phonetic navigation method, need voice broadcast in navigation procedure time, generate the report statement that will read by the report statement template in configuration template file, owing to can upgrading at any time or revise configuration template file, the content that therefore can change voice broadcast, has improved user's experience.
Embodiment bis-:
The schematic flow sheet of the phonetic navigation method that Fig. 2 provides for another embodiment of the present invention, as shown in Figure 2, the embodiment of the present invention comprises the steps:
Step 201, if determine and need voice broadcast according to the distance between the primary importance information at the current place of mobile device and the second place information at induction point place, determines the type information of induction point, execution step 202.
Step 202 is obtained and induces a little corresponding report statement template, execution step 203 according to the type information of induction point from configuration template file.
Step 203, determines the preset parameter of reporting in statement template and reports the variable element in statement template, execution step 204 according to the type information of induction point.
Whether step 204, can determine variable element according to the type information of induction point, if so, performs step 205, if not, and execution step 206.
Step 205, generates the report statement that will read according to preset parameter and variable element, execution step 207.
Step 206, deletes the corresponding minor sentence of variable element of reporting in statement, and the report statement of deleting after minor sentence is generated to the speech text that need to report, execution step 207.
Step 207, generates according to reporting statement the speech text that needs report, and carries out voice broadcast according to speech text.
Be elaborated to embodiment illustrated in fig. 2 below in conjunction with Fig. 3, as shown in Figure 3, triangle represents the residing position of mobile device, the position of circular representative induction point, this induction point expression mobile device need to be turned right, and the direction of arrow is that navigational system is the guidance path that drives towards East Road, Shangdi by West Road, Shangdi that user recommends.
In the time that user goes to crossing, need carry out voice broadcast prompting user turns right.The content that this statement is reported obtains by reading configuration template file, according to mobile device, (next road is called " six streets, Shangdi " with inducing the distance of point and the attribute of induction point self, roughly direction is " Shangdi road direction ") resolve the statement reading from configuration template file, generate the speech text that needs report
In step 201, navigational system need to get the primary importance information at the current place of self driving and the second place information at induction point place, distance by primary importance information and second place acquisition of information between the two, need to be when carry out navigation speech prompting according to induction point when judging, determine the type information of induction point, in the embodiment of the present invention, to induce the right-hand rotation of a distance in crossing to carry out exemplary illustration.
In step 202, in the time that the type information of induction point is right-hand rotation, from configuration template file, obtain and the report statement template of turning right corresponding, in one embodiment, this report statement template is " front × × rice is turned right, and enters × × road past × × road direction ".
In step 203, because the type information of induction point is right-hand rotation, therefore the type information of putting by induction is determined the preset parameter of reporting in statement template and is reported the variable element in statement template, in one embodiment, in the report statement template shown in above-mentioned steps 202, " front, turn right, enter, toward, direction " is the preset parameter in this report statement template, " × × rice, × × road, × × road " be the variable element in this report statement template, in one embodiment, variable element is " 500 meters, six streets, Shangdi, East Road, Shangdi ".
In step 204, if in actual navigation procedure, although adopted report statement template " front × × rice is turned right; enter × × road; past × × road direction ", but in actual guidance path, the type information of putting by induction is determined not " past × × road direction " this minor sentence, now needs the minor sentence at variable element place to delete.
In step 205, generate the report statement that will read according to preset parameter and variable element, as shown in Figure 3, according to above-mentioned definite preset parameter and variable element, the report statement reading is " right-hand rotation of 500 meters, front, enters six streets, Shangdi, toward West Road, Shangdi direction ".
In step 206, for example, need " past × × road direction " this minor sentence to delete, the report statement of deleting after minor sentence is generated to the speech text that needs report, raw speech text is for example: " front × × rice is turned right, entered × × road ".
In step 207, can pass through phonetic synthesis (Text To Speech, referred to as TTS) technology and speech text is converted into sound, and play by player.
The embodiment of the present invention provide phonetic navigation method, need voice broadcast in navigation procedure time, generate the report statement that will read by the report statement template in configuration template file, owing to can upgrading at any time or revise configuration template file, the content that therefore can change voice broadcast, has improved user's experience.
