DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a vehicle and a control method thereof will be described in detail with reference to the accompanying drawings.

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

1, a vehicle 100 includes a voice input unit 110 for receiving voice of a user, a storage unit 120 for storing voice of an input user, a voice recognition unit 130 for recognizing voice of the user, A control unit 140 for controlling the operation corresponding to the recognized voice to be executed, and a display unit 151 for displaying information related to the operation corresponding to the recognized voice. In the embodiment of the disclosed invention, it is assumed that the user includes both the driver and the passenger boarded on the vehicle 100. [

The voice input unit 110 may include a microphone, and when a user's utterance voice is input, the voice input unit 110 converts the utterance voice into an electrical signal. The storage unit 120 may temporarily store the user's voice temporarily or temporarily, and the stored voice may be transmitted to the voice recognition unit 120. The storage unit 120 may include a nonvolatile memory or a volatile memory. Also, the storage unit 120 may be separately implemented as a buffer for storing voice, or may store other information together.

The speech recognition unit 130 includes a speech recognition engine. The speech recognition engine recognizes speech uttered by the user by applying a speech recognition algorithm to the inputted speech, generates a recognition result can do.

At this time, the input voice can be converted into a more useful form for voice recognition, and the start point and the end point are detected from the voice signal and the actual voice interval included in the inputted voice is detected. This is called EPD (End Point Detection).

The characteristics such as cepstrum, linear predictive coding (LPC), mel-frequency cepstral coefficient (MFCC), or filter bank energy are detected within the detected interval. The feature vector of the input speech can be extracted by applying the vector extraction technique.

Then, the recognition result can be obtained by comparing the extracted feature vector with the trained reference pattern. For this purpose, an acoustic model for modeling and comparing the signal characteristics of speech and a language model for modeling the linguistic order relation of words or syllables corresponding to the recognition vocabulary can be used.

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 voice recognition unit 130 may use any of the above-described methods for recognizing the voice. For example, an acoustic model with a hidden Markov model can be used, or an N-best search method using an acoustic model and an audio model can be used. The N-best search method can improve the recognition performance by selecting up to N recognition result candidates using the acoustic model and the language model, and then re-evaluating the ranking of these candidates.

The speech recognition unit 130 may calculate a confidence value to secure the reliability of the recognition result. The confidence value is a measure of how reliable the result is to speech recognition results. For example, a phoneme or word recognized as a result can be defined as a relative value of the probability that the word has been uttered from another phoneme or word. Therefore, the confidence value may be expressed as a value between 0 and 1, or as a value between 0 and 100.

When the confidence value exceeds a predetermined threshold value, the recognition result may be output to the control unit 140 so that the operation corresponding to the recognition result is performed. If the confidence value is equal to or less than the threshold value, (rejection).

The speech recognition unit 130 may be embodied in a computer-readable recording medium using software, hardware, or a combination thereof. According to a hardware implementation, a plurality of application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs) An electronic unit such as a micro-controller, a micro-processor, or the like.

According to a software implementation, it may be implemented with separate software modules that perform at least one function or operation, and the software code may be implemented by a software application written in a suitable programming language.

The control unit 140 may control various components included in the vehicle 100 to perform an operation corresponding to the recognition result output by the voice recognition unit 130. [ The output recognition result may be a command included in the voice uttered by the user, and the controller 140 may perform the operation mapped to the recognized command. For example, if the recognized command is a command related to dialing, the control unit 140 may perform control for dialing.

If the controller 140 is not in a state capable of performing the operation mapped to the recognized command, the control unit 140 displays information related to the command on the display unit 151 to determine the current state of the user, So that it can take appropriate actions.

FIG. 4 is a flowchart illustrating a process performed by a vehicle according to an embodiment of the present invention.

In one example, the vehicle 100 can recognize the user's voice and perform the telephone call. In the following embodiments, the operation of the vehicle 100 will be described in detail with reference to telephone dialing.

When a user inputs a voice including a command for performing telephone dialing using the vehicle 100 through the voice input unit 110, the voice input unit 110 converts the voice input into an electrical signal, ) Stores the voice converted into an electrical signal.

The control unit 140 checks whether or not the preparation for performing the current telephone dialing is completed. If the preparation is completed, the control unit 140 processes the recognition result of the command. If the preparation is not completed, the control unit 140 displays the preparation state, Provide information.

The control unit 140 determines whether or not the vehicle 100 is connected to the user's terminal and if the data of the phone book stored in the user's terminal is stored in the vehicle 100, And whether or not a database used for determining whether or not the data of the telephone directory is included in the command that the user has uttered is generated. Here, the user terminal may be an electronic device capable of performing a telephone dialing function such as a smart phone, a tablet PC, a smart watch, a smart glass, and the like, and does not limit the kind thereof.

The vehicle 100 and the terminal of the user may be connected by wire or wirelessly. In the case of wireless connection, various wireless communication methods can be applied, and a suitable wireless communication module may be provided in the vehicle 100 and the user's terminal. For example, the vehicle 100 and the user terminal can be connected through the Bluetooth communication method. For this, the Bluetooth communication module may be included in the vehicle 100 and the terminal of the user.

The phone book stored in the user's terminal includes the name or name and the phone number information mapped thereto. In the following embodiments, the information included in the phone book is called phone book data.

When the phone book data is received from the terminal of the user connected to the vehicle 100, that is, the phone book data is downloaded, the name or the name stored in the phone book data can be called and the phone number mapped to the phone book can be called. The control unit 140 may generate a phonebook database (DB) for recognition, which is used for voice recognition after downloading the phonebook data. The voice recognition unit 130 may recognize that the command uttered by the user is a phonebook database The name or the name included in the name < / RTI >

That is, in order to perform telephone dialing through voice recognition, connection between the terminal and the vehicle 100, downloading of phonebook data, or creation of a phonebook database for recognition must be preceded. Accordingly, in order to determine whether or not the vehicle 100 is ready for telephone dialing, the control unit 140 determines whether the connection between the terminal and the vehicle 100, the creation of the phonebook database for downloading and recognizing phonebook data, At least one of them can be judged. In some cases, when at least one of them is completed, it may be determined that the phone is ready to be dialed, or it may be determined that the phone is ready for dialing only when all of them are completed.

For example, it is also possible to perform telephone dialing without using telephone book data. In this case, it is also possible to determine whether the terminal is connected to a vehicle only.

As a result of the determination by the control unit 140, if the preparation for performing the telephone dialing is not completed, the control unit 140 may provide the user with information about the current ready state. For example, the control unit 140 may visually provide information through the display unit 151 can do. Hereinafter, a method of providing visual information will be described with reference to Figs. 5 to 8. Fig.

Figs. 5 to 8 are examples of screens for indicating the ready state for dialing. Fig.

Referring to FIGS. 5 and 6, the display unit 151 may display progress bars 151a and 151b in one area to provide information about the ready state. For example, the current readiness can be expressed as a percentage, which allows the user to view the progress bar 151a, 151b to confirm that 80% of the preparation for dialing has been completed, Can be performed.

Alternatively, in order to more intuitively provide the information on the current ready state, an icon 151c indicating the remaining time remaining until the preparation is completed as shown in Fig. 7 may be displayed. Alternatively, it is also possible to display the remaining time in the form of a progress bar. There is no restriction on the way in which information about the ready state is provided. It is also possible to provide visual information through the display unit 151 as well as auditory information through the speaker 161.

As described above, according to the vehicle 100 according to the embodiment, when the preparations for performing telephone dialing are not completed, rather than ending the speech recognition immediately, It is possible to determine when to perform a telephone call using voice recognition.

On the other hand, when the user terminal is not connected to the vehicle 100, the user's operation for connecting the terminal is required. Accordingly, in this case, as shown in FIG. 8, a pop-up 151e including a message to connect the terminal can be displayed on the display unit 151. [

In addition, when the preparation for performing the telephone dialing is not completed, the display unit 151 displays the screen before performing the voice recognition again, thereby allowing the user to continuously use the function originally used by the user Let's do it. For example, when the user uses the navigation function, the display unit 151 returns to the route guidance screen as shown in FIGS. 5 to 8, and performs route guidance until the preparation for the telephone call is completed.

FIG. 9 is a flowchart for explaining an operation after preparation for telephone dialing is completed, and FIG. 10 is an example of a screen for inducing a user to re-call.

Referring to FIG. 9, the process of storing the input voice, confirming the ready state, and displaying the ready state when the preparation is not completed, is as described in the example of FIG.

When the preparation for dialing is completed, the voice recognition unit 130 receives the voice stored in the storage unit 120 and recognizes the command included in the transmitted voice. At this time, the instruction can be recognized by using the phonebook database for recognition.

As described above, the speech recognition unit 130 can calculate the confidence value for the recognized command. When the confidence value exceeds the preset threshold value TH, it is determined that the reliability of the result is guaranteed, And processes corresponding recognition results. For example, if the recognized command corresponds to a name or a name included in the recognition phonebook database, the telephone number mapped to the corresponding name or name can be dialed.

However, if the trust value is less than or equal to the preset threshold value TH, the user can be induced to recur. In this case, as shown in FIG. 10, by displaying a detailed guide screen 151d related to telephone dialing on the display unit 151, it is possible to guide the user to easily grasp which command is to be uttered at the present stage have.

The commands that can be ignited for dialing are "call name", "dial #", "redial", "call history", etc. as shown in the example of FIG. Here, "name" means a name or a name desired by the user, and "#" means a telephone number desired by the user.

If the user speaks a "call name ", a call can be made to the telephone number mapped to that name or name, and if dialing" dial # " When "redail" is uttered, the most recently dialed telephone number can be dialed again, and when a "call history" is uttered, a recent call list can be displayed on the display unit 151.

FIG. 11 is a flow chart of operations further detailing the previous step for confirming the ready state of dialing.

Referring to FIG. 11, when a user inputs a voice through the voice input unit 110, the storage unit 120 stores the input voice, and the voice recognition unit 130 recognizes the input voice. That is, it recognizes a command included in the input voice. At this time, the speech recognition unit 130 can use a basic database provided by itself.

When the recognized command is a command relating to a telephone call, for example, when a command such as "call "," dial ", etc. is included in the recognized command, the control unit 140 determines that the intention of the user is a telephone call , It can be determined whether or not the preparation for performing the telephone dialing is completed. The commands related to dialing may be included in the basic database, and information about which command is related to dialing may be stored in advance in the storage unit 120 or the control unit 140. [

If the preparations are not completed, the preparation status is displayed. When the preparation is completed, the speech recognition unit 130 recognizes the command and performs processing corresponding to the recognition result. At this time, the voice recognition unit 130 can recall the voice stored in the storage unit 120 and recognize it using the phonebook database for recognition, not the basic database.

If the recognized command is not related to dialing, the corresponding process can be performed. For example, if the recognized command is an instruction for controlling an audio, video, or navigation function, the corresponding process can be performed.

That is, according to this example, it is possible to prevent unnecessary operations from being performed by determining the ready state for dialing only when the command uttered by the user is a command related to dialing.

However, the embodiment of the vehicle is not limited to this, and regardless of whether or not the command uttered by the user is a command related to the telephone call, whether or not the preparation for performing the telephone call is completed, It is also possible to judge.

Hereinafter, an embodiment related to a vehicle control method will be described.

The above-described vehicle 100 can be used in the control method of the vehicle according to the embodiment. Therefore, the description with reference to Figs. 1 to 11 can be similarly applied to the control method of the vehicle.

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

Referring to FIG. 12, a voice input by the user is input through the voice input unit 110 (310). For example, the voice input unit 110 may be turned on by a user's operation.

The storage unit 120 stores the inputted voice (311), and the voice recognition unit 130 recognizes a command included in the voice of the user using the basic database (312).

The control unit 140 determines whether the recognized command is a command related to dialing (313). For example, when the command includes a command such as "call" or "dial ", it can be determined that the command is related to dialing.

If the command is not related to dialing (NO in 313), the process for performing dialing is terminated and a process corresponding to the recognized command is performed.

If the recognized command is a command related to dialing (YES in 313), the state of ready to dial is checked (314). For example, it may be determined whether or not the user's terminal is connected to the vehicle 100, whether the user has downloaded the phone book data, and whether the phone book database for recognition has been created. If either of these is not completed, it can be judged that the preparation is not completed.

If the preparation is not completed (No in 315), the ready state can be displayed (318). For example, a progress bar 151a or 151b indicating a ready state as a percentage may be displayed in one area of the display unit 151, or an icon (for example, 151c. There is no restriction on the way in which information about the ready state is provided. It is also possible to provide visual information through the display unit 151 as well as auditory information through the speaker 161.

When the preparation is completed (YES in 315), the command is recognized using the phonebook database for recognition (316) and the recognition result is processed (316). At this time, even if the user does not recommand the command, the voice stored in the storage unit 120 can be called again and recognized. The processing of the recognition result means performing the operation corresponding to the recognized command. When the recognized command includes the name or the name, the terminal can perform the telephone call to the telephone number mapped to the name or the name, If the number is included, the telephone number can be dialed. If the redial is included, the most recent telephone number can be dialed.

13 is a flowchart illustrating a process of processing a recognition result in a vehicle control method according to an embodiment.

Referring to FIG. 13, a voice is received from a user (320), a voice is stored (321), a command is recognized using a basic database (322), a command related to dialing (Step 324). When the preparation is not completed (step 325 is NO), the process of displaying the ready state (step 320) is the same as the example of FIG. 12 described above.

When the preparation for dialing is completed (325), the command is recognized (326) using the phonebook database for recognition and a confidence value is calculated for the recognized command.

If the confidence value exceeds the preset threshold value TH, the recognition result is processed. If the confidence value does not exceed the predetermined threshold value TH, the user is induced to re-enter 329. [ In the latter case, since it is already known that the intention of the user is performing the telephone call through voice recognition, a screen for guiding the user's utterance related to telephone dialing can be displayed, as shown in FIG.

12 and 13, the following description is made on the assumption that the command included in the input voice is a command related to the telephone dialing, and that the subsequent operation such as checking the telephone preparation ready status is performed. However, But is not limited thereto. It is also possible to check the ready state for dialing regardless of whether the command included in the input voice is a command related to the dialing, as described in the embodiment of the vehicle.
