Detailed description of the invention
For making above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the realization flow figure of the navigation speech broadcasting method that the present invention is based on configuration file; As shown in Figure 1, the navigation speech broadcasting method that the present invention is based on configuration file comprises the steps:
Guiding key element in step one, extraction boot statement, as keyword, forms lists of keywords;
In extraction boot statement, " guiding key element " is as " word ".Such as " front [300 meters], sail on [North 2nd Ring Road/South 3rd Ring Road/abundant Cheng Lu/Chang'an street] to [turn left/turn right] through [rotary island]." wherein between [], part is extracted as " word "; for class " word " defines a keyword keyword; that statement so just can be expressed as: " front [keyword_distance], sails into [keyword_roadname] to [keyword_turn] through [keyword_type]." the most important thing is " guiding key element " to separate with language environment here; if English guiding used instead in the statement such as can become [keyword_distance] ahead [keyword_turn] intothe [keyword_roadname]. " and then get this this keyword formation Keyword List, as: [keyword_turn] can be " left-hand rotation " " right-hand rotation " " revolution " " left front turning ".
Step 2, analyze the form at various different crossing, obtain the different statement templates for different crossings form;
Analyze the form at various different crossing, obtain different statement templates.Such as: a template is obtained as " front is walked [right side/left side] [outlet/entrance] [roll away from/sail into] [main road/bypass] for the crossing type going out main road."; Another template is obtained as " front [300 meters] place to [turning right/left], and then [turning right/left] sails on [so-and-so road] for continuous print two crossings.”。The form at tens kinds of crossings can be analyzed thus, obtain tens kinds of statement templates.
Add the disaggregated classification of some templates:
Such as to same crossing, " front [keyword_distance], sails into [keyword_roadname] to [keyword_turn] through [keyword_type] to use template time distance crossing is far away." " [keyword_turn] sails into [keyword_roadname] to use brief statement when having driven to crossing.", segmentation template can be more humane.When distance crossing is near, tip distance is nonsensical, and if the final voice generated are oversize can incur loss through delay to fall best report opportunity.Such as to outlet configuration special template special on through street, shape is as " front [keyword_distance] second exports to keep right and roll away from, sails into [keyword_roadname].”
Step 3, described statement template and described lists of keywords are write in configuration file;
The statement template obtained by step one, step 2 above and lists of keywords are write in configuration file.When Navigator runs, by real-time analysis crossing form, search statement template corresponding in configuration file, the keyword in filling template can obtain " phonetic order ".Can complete by writing different template profile for different language, eliminating amendment application program.
Step 4, by GPS locating information real-time analysis crossing form, search the statement template of corresponding crossing form in configuration file;
In this step, by corresponding with map datum for GPS locating information, determine that vehicle is positioned on certain road, find follow-up crossing along Planned Route.
Take out the map datum at follow-up crossing, according to crossing shape and attribute information analysis, confirm that this crossing meets certain model in " the statement template " that step 2 exports, choose a certain bar statement according to from the distance at crossing and road name information.
Step 5, according to GPS locating information, the keyword of corresponding crossing form to be filled in found statement template, thus to form phonetic order.
In this step, take out the keyword in statement, such as " [keyword_turn] sails into [keyword_roadname] statement." in; take out " [keyword_turn] "; according to the crossing direction information analyzed in step 4; the lists of keywords in finding step one in generating configuration file; i.e. table 1 above, such as, find " left-hands rotation ", " [keyword_roadname] " is replaced to the road name after turning " so-and-so road "; i.e. exportable " left-hand rotation, sail into so-and-so road ".The configuration file generated in step one controls the generation of final phonetic order.
Which feature " phonetic order " that first the present invention analyzes for guiding has, and which its guiding will have.Then extract these key elements as keyword, form grammatical statement; The degree of lip-rounding of satisfying the need again state is classified, and every class crossing form is correspondence independently grammatical statement all, and all grammatical statements converge into configuration file.Finally read " grammatical configuration file " by programmed algorithm to fill a vacancy to its parsing, synthesize " phonetic order " of complete smoothness.The readability of configuration file, easily revise characteristic, determine high-adaptability of the present invention, configurability, solve the problem of custom that " phonetic order " adapts to different regions, dialect or country variant language; Indication different grammatical statement in each type crossing is expressed, solves the problem that " phonetic order " is dull, machinery is stiff, make expression variation, hommization.
" phonetic order " as referred to herein generates, and only refers to the generation of this section of word, does not comprise the conversion of word to sound.Prior art does not carry out analytic induction to " the guiding key element " that guide in voice, sums up the syntax, so have no idea carry out collocation method by configuration file, also reaches the hommization of " phonetic order " and easy configurability with regard to illegal.The present invention, by first carrying out analytic induction to " guiding key element " in " phonetic order ", sums up the syntax, then the syntax is write in grammatical configuration file.By changing easily and enriching grammatical configuration file, the hommization of " phonetic order " can be reached and easily configure.In addition, prior art degree of lip-rounding state of not satisfying the need carries out sorted generalization, does not use the different syntax to go to generate " phonetic order ", so use general prompting " left-hand rotation " " right-hand rotation " most crossing to each class, such suggestion content is simply stiff, and " phonetic order " kind is abundant not.The present invention carries out sorted generalization by degree of lip-rounding state of satisfying the need, to " phonetic order " method of the different hommization of every type crossing form generating, easily the multiple syntax are configured in a configuration file by 1 middle configuration file above, reach " phonetic order " of the hommization generating abundant species fast.Because crossing form kind is very many, can be increased fast abundant " phonetic order " by amendment configuration file.
What we had developed is digital map navigation product, and main guiding principle during product work is:
1, GPS receives customer position information, relates to GPS module
2, matched position in map datum and the route planned, finds user to the crossing arrived, will relate to location matches module.
3, " phonetic order " module guided is generated.
3.1 data analysis crossing forms according to the map, take out crossing morphotype Type, analyze crossing and the information TurnInfo such as to turn to.
3.2 according to crossing morphotype Type, reads template profile, searches the statement template Template of corresponding morphotype Type.
3.3 according to crossing shape information TurnInfo content, and statement template Template, filling template, generates " sentence instruction ".
4, utilize text to sound modular converter, " phonetic order " is played back by sound, relates to voice playing module.
More than main modular related to the present invention, wherein core of the present invention in the 3rd module 3.1,3.2,3.3 3 submodules.
Also have other module, be connected with the present invention less, as modules such as map denotation.Be not described in detail at this.
Key of the present invention is to use a kind of method based on configuration file to realize program guide command to the conversion based on natural language speech instruction, it is all the natural language output directly directly being generated guiding by program that the navigation speech that industry is passed through reports scheme, higher customization cost certainly will be needed like this when adaptive different language and navigation needs, the present invention then devises a kind of natural language speech method for transformation based on configuration file, this design key is: by the dictionary of key definition phonetic representation, by the syntactic structure of statement template definition phonetic representation, achieve the automatic generation of voice configurationization in this way.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
