Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a vehicle,
The present invention relates to a navigation device capable of operating by inputting a target operation by voice.

[0002]

2. Description of the Related Art In recent years, instead of manually inputting instruction commands and the like, an operator speaks words,
Make the voice instructions recognize the instructions in words,
For example, a complicated input operation of an in-vehicle navigation device and an input operation during traveling have been omitted.

As this type of navigation device, for example, as shown in FIG. 3, a control unit (central processing unit)
1, a point database 2, a display means 3, a speaker 4,
In some cases, the navigation device 100 is constructed by connecting the microphone 5, the voice recognition unit 6, the voice synthesis unit 7, the route search unit 8, and the control switch 9.

As shown in the flow chart of FIG. 4, when a control switch 9 for starting / stopping voice input is depressed, the control unit 1 controls the respective units of the navigation device 100 to activate a voice recognition mode. When the process is started (step P1), for example, when a name of a point such as “XX golf course” stored in the point database 2 to be subjected to the navigation operation is input by voice from the microphone 5, the input voice is input. Is recognized by the voice recognizing means 6 (step P2), and the voice data of the recognition result generated by the voice synthesizing means 7 is output to the speaker 4 and read back as a response to the voice input (step P3). A map of the point is displayed on the display means 3 (step P
4).

[0005] Next, when the control unit 1 recognizes a normal voice recognition by the repetition, and receives voice input, the voice recognition unit performs voice recognition of a function instruction to execute any of the navigation functions (step P5). ), For example
If the recognition result is "destination setting" for performing a route search with the designated point as the destination, the recognition result is repeated (step P6), and the recognition point "O" A search for a route to the "golf course" is started (step P7).

[0006] The function instructions include "destination setting" for performing a route search using a designated point as a destination in the same manner as "destination setting", "point registration" for registering a point according to a user in memory, and the like. “Point registration” and the like are prepared in advance for each application, and various function instructions can be given.

[0007]

However, in such a conventional navigation device, a utterance for setting a point to be processed and an utterance for instructing a function are provided twice in total. There is a problem that confirmation is required, the operation becomes complicated, and it takes time to execute the function.

[0008] Even if the user instructs a function, the user must speak the set word in order to give an appropriate instruction, and the vocabulary is different from a point or an instruction. Therefore, there was a problem that it was difficult to understand and to remember easily.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a point navigation function using natural wording can be provided by designating a point and a function instruction with a single utterance. It is intended to provide a navigation device with excellent operability by realizing processing instructions and shortening the operation time up to function execution.

[0010]

According to the present invention, there is provided a navigation apparatus comprising: a point database for storing a group of points to be processed; and a function instruction database for storing a group of instructions for processing functions such as navigation for the points to be processed. Voice recognition means for recognizing a continuous utterance of two or more words by an unspecified speaker or the like; and the utterance of the operator recognized by the voice recognition means is used to specify a point in the point database and an instruction in the function instruction database. And processing means for executing processing by a processing function such as navigation in accordance with the instruction of the recognition point in the case of continuous operation.

With this configuration, the operator (such as an unspecified speaker) makes a single continuous utterance combining a point and an instruction to process the point, and targets the point specified by the utterance. , The execution of the processing by the processing function such as the navigation provided can be started, and the processing result by the processing function can be provided to the operator. Therefore, the designation of the point and the designation of the function instruction can be performed by one voice input, and the operation time until the execution of the processing function can be reduced. Also, as the instruction of the function to be uttered after the point, it is possible to register a vocabulary to be uttered with natural wording, and to keep the general function instruction continuous to the point, It is possible to reduce a burden such as repeating instructions. As a result, the operability of the navigation device can be improved.

Here, the instruction group of the processing function includes:
A vocabulary for performing a route search with the point as a destination, a vocabulary for a user to arbitrarily set and register the point, a vocabulary for displaying a map of the point, or various information of the point is presented. Is preferably stored in the function instruction database.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 and 2 are views showing an embodiment of a navigation device according to the present invention.

Referring to FIG. 1, a navigation device 10
A control unit (central processing unit) 11 for centrally controlling each unit of the apparatus stores a point database 12 in which point groups (vocabularies) such as place names, addresses, and facility names to be processed are stored.
A display unit 13 for displaying various information such as a map such as a current position and a destination; and a speaker 1 for reproducing audio data.
4, a microphone 15 for collecting a speaker's voice, a voice recognition unit 16 for recognizing two or more continuous voices uttered by an unspecified speaker, and converting data to be notified to the operator into voice data. In addition to the voice synthesizing means 17, a route searching means 18 for searching for a route to the destination, and a control switch 19 pressed when starting / stopping voice input, a point stored in the point database 12 A function instruction database 22 that stores an instruction group (vocabulary) for executing a navigation function that processes the point data is connected to the data.

When the vocabulary stored in the point database 12 and the function instruction database 22 is a speech recognition result, the control unit 11 executes the navigation function by processing the speech recognition result of the utterance of the operator. Even when the utterance of the operator is a continuation of the point data in the point database 12 and the instruction data in the function instruction database 22, the processing by the navigation function according to the instruction data corresponding to the point data is performed. Execute. That is, the control unit 11 constitutes a navigation processing unit.

Specifically, the point database 12 includes:
For example, while location data such as place names such as “XX golf course”, “XX amusement park”, and “XX town” are stored, the function instruction database 22 stores, for example, Clarify the content of the instruction alone, such as "Destination setting" or "Destination setting" to search the route with the destination as the "point registration" or "point registration" to register the point according to the user in memory In addition to the basic instruction data, general instructions that are continuous in natural terms following the point are stored in advance. For example, (1) utterance follows a designated point as a destination when performing a route search or the like. (2) When registering a point corresponding to the user in memory, such as “go to”, “go to”, “route to”, etc.
(3) When a map of a designated point is displayed, a "map of" or "display" is uttered after the designated point, and (4)
When presenting various information such as traffic information and weather forecast of a designated point, “no traffic information” and “no weather” uttered after the designated point correspond to the point stored in the point database 12. For each use, a set of instructions (vocabulary) for executing the navigation function with the point as a processing target is stored in advance in natural terms generally uttered after the point. The vocabulary data stored in the point database 12 or the function instruction database 22 may be configured to be added from the microphone 15 or the like by specifying a navigation function in addition to being set in advance. It may also be possible to increase the number of functions and expand the range of recognizable wording.

Then, as shown in the flowchart of FIG. 2, the control section 11 starts and starts a voice recognition mode in response to pressing of a control switch 19 for starting / stopping voice input (step P11). When the voice of “go to golf course” is continuously input from the microphone 15, the input voice is voice-recognized by the voice recognition unit 16 (step S <b> 1). P12) As a response to the voice input, the voice data of the recognition result generated by the voice synthesizing means 17 is output from the speaker 14 and read back (step P13), and the voice recognition result becomes a target of the processing operation by the navigation function. Point database 1
2, point data of “XX golf course” stored in
It is determined that the “go to” instruction data stored in the function instruction database 22 has been uttered continuously, and a map near the recognized point “XX golf course” is displayed on the display means 13. At the same time (step P14), a route search (navigation process) by the route search means 18 to the point (destination) of the "XX golf course" is started according to the instruction of "go to" in the recognition result (step P17).

Therefore, the operator only utters once a general general phrase of a point and an instruction, and does not perform voice recognition and repetition at each of the point and the instruction. , The processing by the navigation function such as a route search to the point can be started in a short time.

As described above, in the present embodiment, it is possible to start processing by a desired navigation function by giving a natural wording instruction corresponding to a point, and to make the operator think about how to give an instruction. Therefore, for example, the processing result of the route search can be promptly provided to the operator without burden. Therefore, it is possible to provide the navigation device 10 having excellent operability.

[0020]

As described above, according to the present invention,
Only one continuous utterance combining a point and an instruction of a processing function following the point can execute processing by a processing function such as navigation for the point. Therefore, it is possible to provide a navigation device that is excellent in operability and that does not require quick operation and does not require the user to consider instruction words.
