5 is a control block diagram of a vehicle according to an embodiment.

5, a vehicle 1 according to an embodiment includes a voice recognition device 100 for recognizing a voice of a user and transmitting a recognition result to the navigation device 200, And a navigation device 200 for setting a destination according to the recognition result and guiding the route.

The control block diagram shows only the voice recognition apparatus 100 and the navigation apparatus 200 in order to explain the embodiment of the present invention. The voice recognition apparatus 100 and the navigation apparatus 200 It is understood that various components may be included.

The speech recognition apparatus 100 includes a microphone 110 for receiving a user's voice, a preprocessor 120 for preprocessing the speech signal, a speech recognition engine 130 for recognizing the preprocessed speech signal, And a control unit 150 for transmitting the voice recognition result to the navigation device 200. The storage unit 140 stores the position information and the voice recognition result.

As described above, the microphone 110 is mounted on the vehicle 1, receives the user's voice, and converts the input voice into an electrical signal. In this embodiment, an electrical signal whose voice is converted is referred to as a voice signal.

The microphone 110 transmits a voice signal to the preprocessor 120, and the voice signal to be transmitted may be an analog signal or a digital signal.

The preprocessing unit 120 removes the noise signal from the voice signal input through the microphone 110 and extracts the feature vector. The preprocessed speech signal may be a digital signal. When the analog signal is input from the microphone 110, the preprocessor 120 may perform analog-to-digital conversion.

The preprocessing unit 120 can extract the feature from the noise-removed speech signal, and the extracted feature may be in the form of a vector. For example, the preprocessing unit 120 may add a cepstrum, a linear predictive coefficient (LPC), a mel-frequency cepstral coefficient (MFCC), or the like to the voice signal from which the noise signal has been removed A feature vector extracting technique such as a filter bank energy can be used to extract a feature vector.

For example, the speech recognition engine 130 may recognize the speech signal by comparing the extracted feature vector with the trained reference pattern. For example, a language model may be used, which models an acoustic model for modeling and comparing the signal characteristics of speech and a linguistic order relation of words or syllables corresponding to the recognition vocabulary. The reference pattern or model used for the comparison of the feature vectors may be stored in the storage unit 140.

The acoustic model can be divided into a direct comparison method of setting a recognition object as a feature vector model and comparing it with a feature vector of voice data, and a statistical method of using the feature vector of the recognition object statistically.

The direct comparison method is a method of setting a unit of a recognition target word, a phoneme, etc. as a feature vector model and comparing how similar the input speech is, and a vector quantization method is typically used. According to the vector quantization method, a feature vector of input speech data is mapped to a codebook, which is a reference model, and is encoded into a representative value, thereby comparing the code values with each other.

The statistical model method is a method of constructing a unit of a recognition object as a state sequence and using the relation between the state strings. The state column may consist of a plurality of nodes. The method of using the relation between state columns is again Dynamic Time Warping (DTW), Hidden Markov Model (HMM), and a method using a neural network.

Dynamic time warping is a method of compensating for differences in the time axis when compared to a reference model, taking into account the dynamic characteristics of the speech, in which the length of the signal varies with time even if the same person pronounces the same. Hidden Markov models, Assuming a Markov process with probabilities and observation probabilities of nodes (output symbols) in each state, we estimate the state transition probability and observation probability of nodes through the learning data, and calculate the probability that the input speech is generated in the estimated model .

On the other hand, the language model modeling the linguistic order relations of words and syllables can reduce the acoustical ambiguity and reduce the errors of recognition by applying the order relation between the units constituting the language to the units obtained by speech recognition. There are statistical language models and Finite State Automata (FSA) based models for language models, and the chained probabilities of words such as Unigram, Bigram, and Trigram are used for statistical language models.

The speech recognition engine 130 may use any of the above-described methods or other known methods in recognizing the speech.

Meanwhile, the storage unit 140 may receive and store a location information database (DB) from the map database 210 of the navigation device 200. The location information database is a set of information in which names stored in the map database 210 and location information of the corresponding names are mapped to each other. In other words, the location information database stores location information indicating a geographical location and at least one name corresponding to the location information, which are mapped to each other. A detailed description of the location information database will be given later.

The control unit 150 compares the command recognized by the speech recognition engine 130 with the position information database stored in the storage unit 140 to determine whether the command entered by the user is a unique name in the map database 210, Whether or not it is a unique name corresponding to the corresponding name.

The speech recognition apparatus 100 transmits the destination information based on the speech recognition result to the navigation device 200. [ When the command inputted by the user corresponds to the unique name, the position information (ID information) corresponding to the command is transmitted to the navigation device 200. If the command does not correspond to the unique name, (200). The description thereof will be more specifically described with reference to FIGS. 6 to 11. FIG.

Also, the controller 150 can control the overall operation of the voice recognition apparatus 100, such as turning on / off the microphone 110. [

The preprocessing unit 120, the speech recognition engine 130, the storage unit 140, and the control unit 150 are connected to a memory for storing various data such as programs and algorithms necessary for performing the respective operations, And a processor for executing data to process the data.

Some or all of the preprocessing unit 120, the speech recognition engine 130, the storage unit 140, and the control unit 150 may share a processor or a memory. That is, one processor performs functions or functions of some of the preprocessing unit 120, the speech recognition engine 130, the storage unit 140, and the control unit 150, or one memory may perform the functions of the preprocessing unit 120, The speech recognition engine 130, the storage unit 140, and the control unit 150. [0034]

The memory may include at least one of a nonvolatile memory such as a flash memory, a read only memory, an erasable programmable read only memory (EPROM), and an electrically erasable programmable read only memory (EEPROM) And a volatile memory such as a random access memory (RAM), a static random access memory (S-RAM), and a dynamic random access memory (D-RAM).

It goes without saying that the speech recognition apparatus 100 may share a memory or a processor with other components of the vehicle 1. [

In addition, the processor and the memory may be provided in a single configuration, a plurality of configurations, physically separated configurations, or a single chip, depending on their capacities.

On the other hand, it is also possible that the speech recognition engine 130 is provided in an external server other than the vehicle 1. [ In this case, the voice signal can be transmitted to the external server through the communication module provided in the vehicle 1, and the recognition result can be received from the external server.

The navigation device 200 includes a map database 210, a position sensor 220, a controller 230, and a display 240.

The map database 210 includes the above-described location information database, and stores map data including various information that can express roads, buildings, and other geographical locations. In addition, the map data may include POI (Point Of Interest) information.

The map database 210 includes at least one of a nonvolatile memory such as a flash memory, a read only memory, an erasable programmable read only memory (EPROM), an electrically erasable programmable read only memory (EEPROM) And may further include at least one of a volatile memory such as a random access memory (RAM), a static random access memory (S-RAM), a dynamic random access memory (D-RAM) It is also possible to do.

The map database 210 may store map data for all the areas supported by the navigation device 200, but may store only map data for some areas.

When only map data relating to a certain area is stored, the vehicle 1 can download necessary map data through a communication module (not shown) from an external server or the like and store it in the map database 210 for use.

The position sensor 220 refers to a sensor that determines the position information of the vehicle 1. [ At this time, the positional information of the vehicle 1 includes a value calculated according to various coordinate systems capable of expressing the position of the vehicle 1. [

According to one embodiment, the position sensor 220 can calculate the coordinates of the position of the vehicle 1 in terms of latitude and longitude. However, the method of representing the coordinates is not limited to this, and it is also possible to express it through various other coordinate systems that can indicate the position of the vehicle 1, such as altitude.

The position sensor 220 may be implemented as a Global Positioning System (GPS) sensor that locates through a satellite, or may be implemented as a DGPS (Differential Global Positioning System) sensor that can measure a position with high accuracy by supplementing a GPS sensor It is possible.

The control unit 230 searches the map database 210 for the set destination and generates a traveling route from the current position to the destination based on the current position of the vehicle 1 acquired from the position sensor 220 and the set destination.

The control unit 230 can display the driving route on the map data and output it via the display 240 and guide the user to the destination along with voice guidance through the speaker 90. [

On the other hand, when the navigation device 200 sets the destination, the destination information transmitted from the speech recognition device 100 can be used. As described above, since the command inputted by the user is a unique name in the map database 210 The location information corresponding to the command can be received and set as a destination. If the name does not correspond to the unique name, the text itself can be searched again in the map database 210.

The control unit 230 may include a memory that stores a program that performs the above-described and later-described operations and various data related thereto, and a processor that executes a program stored in the memory. The description of the memory is the same as the description of the memory included in the voice recognition apparatus 100, and thus will be omitted.

The controller 230 may share a memory with the map database 210 and may share a processor or memory with other components of the voice recognition apparatus 100 and other vehicles 1. [

6 is a diagram illustrating an example of a location information database stored in a speech recognition apparatus according to an embodiment.

As described above, the location information database received from the navigation device 200 is stored in the storage unit 140 of the voice recognition apparatus 100.

As shown in FIG. 6, the location information database stores ID information indicating location information and at least one name corresponding to the location information. That is, the storage unit 140 may receive not only the text information of the name corresponding to each position included in the map database, but also the ID information of the corresponding position from the navigation device 200 and store the same.

On the other hand, even if they are at the same position, they can be referred to as a plurality of names. That is, a plurality of names may be used to represent one position. For example, as in the example of Fig. 6, the specific location having the ID information of 9526558 / 0x2202 / 1165010200 may be referred to as "A-mat " That is, a certain user can search for "A-Mart" to input a specific location having the ID information as a destination, and other users can search for "A-mat store".

In addition, the feature position having the ID information of 3014827 / 0x2202 / 1126010500 may be referred to as "A-mat" or may be referred to as "A-mart rendezvous point ". Therefore, the feature position having the ID information of 9526558 / 0x2202 / 1165010200 and the feature position having the ID information of 3014827 / 0x2202 / 1126010500 are all located at geographically different positions, but all can be called "A-Mart".

Therefore, the location information database stores all of a plurality of names (name 1, name 2) that can represent respective positions. In this example, for convenience of explanation, only the names 1 and 2 are stored, but it is needless to say that a greater number of names may be stored for each ID information.

FIG. 7 is a diagram illustrating an operation of a speech recognition apparatus and a vehicle including the same according to an embodiment of the present invention. FIGS. 8 and 9 are diagrams illustrating a process performed when a command input by a user corresponds to a unique name, FIGS. 10 and 11 are diagrams illustrating a process performed when a command input by a user does not correspond to a unique name. In the following example, it is assumed that the location information database shown in Fig. 6 is used.

7, when the user inputs (S11) the "A-mat store" as a command, the microphone 110 converts the input user's voice into an electrical signal, The engine 130 performs speech recognition (S12) and outputs the recognition result.

The speech recognition result may be the text of the "A-mart shop ". The control unit 150 searches the location information database stored in the storage unit 140 for "A-Mart storehouse" and determines whether the name is a unique name (S13).

In this embodiment, the unique name means a unique name in the location information database. The control unit 150 determines whether the recognized command is identical to the name in the location information database. That is, when the same name as that recognized in at least one name included in the location information database corresponds to only one location information, the controller 150 can determine the recognized command as a unique name.

8, when the user uttered and input the "A-mat suitcase" as a command and the speech recognition apparatus 100 outputs "A-mat suitcase" as a recognition result, the name 1 and the name 2, the same name as the "A-shopping plaza store" is only a name for a location having ID information of 9526558 / 0x2202 / 1165010200. Accordingly, the control unit 150 can judge that the "A-mart shop" is a unique name.

In this case, the speech recognition apparatus 100 transmits the ID information of 9526558 / 0x2202 / 1165010200, that is, the location information, instead of delivering the text of the "A-mark store location" to the navigation device 200 (S14).

Referring to FIG. 9 together, the navigation device 200 sets the corresponding location information as a destination (S15), and can perform route guidance to the set destination. At this time, the display 240 can display a screen 242 indicating that the A-shopping center is set as a destination, and displays an OK button 242a and a cancel button 242b together, It is also possible to confirm the destination by

4, the navigation device 200 does not need to retrieve all the names of the "A-mark storehouse" in the map database 210, and the user does not need to repeatedly input unnecessary selections do.

10, when the user uttered and input "A-mat" as a command and the speech recognition apparatus 100 outputs "A-mat" as a recognition result, the names 1 and 2 Of the eight names included in the name "A-mat" is the name for the location having the ID information of 9526558 / 0x2202 / 1165010200 and the name for the location having the ID information of 3014827 / 0x2202 / 1126010500. Therefore, the control unit 150 can judge that "A-mat" is not a unique name.

In this case, the voice recognition apparatus 100 transmits the text of "A-mat" to the navigation device 200 (S16).

The navigation device 200 can search for and display the name including the "A-mat " in the map database 210 (S17). As shown in FIG. 10, the names including "A-Mart" are A-Mart, A-Mart (Yangjae Branch), A-Mart (Sangbong Branch), BA Mart, BA Mart ), Which is a total of six.

The navigation device 200 may display a list 241 containing the searched names on the display 240 as shown in Figure 11 to allow the user to select a desired destination. At this time, additional information such as the address of each name or the distance from the current position may be displayed together to help the user identify the location of each name.

That is, when the command uttered by the user does not correspond to the unique name, that is, when there are a plurality of different positions having the command as the name, all of the names including the command are searched for and displayed, Allows you to enter a destination.

Hereinafter, an embodiment of a vehicle control method including a voice recognition device and a navigation device will be described. The vehicle 1 according to the embodiment described above is applied to the control method of the vehicle according to the embodiment. The vehicle 1 includes the voice recognition device 100, the navigation device 200, and the voice recognition device 100 described with reference to Figs. 1 to 11 The description and the drawings relating to the vehicle 1 to be described later can be similarly applied to the control method of the vehicle described later.

12 is a flowchart of a method of controlling a vehicle according to an embodiment.

Referring to FIG. 12, a command for setting a destination is input from a user through a microphone 110 (410). The microphone 110 converts the input voice into a voice signal, which is an electrical signal, and transmits the voice signal to the preprocessing unit 120. The voice recognition engine 130 recognizes the inputted command using the voice signal transmitted (411).

When the speech recognition engine 130 outputs the speech recognition result, that is, the recognized command, the controller 150 compares the recognized command with the position information database stored in the storage unit 140 to determine whether the recognized command is a unique name (412). The description of the location information database and the unique name is the same as described in the embodiments of the speech recognition apparatus 100 and the vehicle 1.

If the recognized command corresponds to the unique name (YES in 413), the position information corresponding to the command is transmitted to the navigation device (414).

The navigation device 200 sets the delivered location information as a destination (415), and can perform route guidance to the set destination. Alternatively, as shown in FIG. 9, it is also possible to display on the display 240 a screen 242 for guiding information on a set destination or buttons 242a and 242b for finally confirming a set destination .

If the recognized command does not correspond to the unique name (NO in 413), the recognized command text is delivered to the navigation device (416). Here, the command text means the recognized command itself.
