Here, the acoustic model refers to a model that models the signal characteristics of the speech and compares it with the input speech, and can statistically process the characteristic of the object to be recognized. The acoustic model can be processed based on the voices of various speakers. In addition, the language model models linguistic order relationships such as words or syllables corresponding to the recognized vocabulary. The language model is a model that can be used in both the speech recognition engine 181 and the translation engine 182, and the acoustic model is a model that can be used in the speech recognition engine 181. The speech recognition engine 181 generates text (eg, a word sequence) based on the search result, which is generated in the same specific language as the input voice. The generated text is input to the translation engine 182.

The translation engine 182 performs a translation operation based on the result input from the speech recognition engine 181. First, the translation engine 182 analyzes text that is an input result. The translation engine 182 performs a desired translation operation through a network or translation software that retrieves translation results. In addition, translation engine 182 may include a number of translation models. Translation models can be created by learning translation knowledge from the corpuses (eg, large monolingual and bandword sentences) that exist in the world. In other words, through repeated translation operations, the translation model can be continuously differentiated and modified.

As such, the speech recognition engine 181 and the translation engine 182 may perform the acoustic translation operation through an acoustic model, a language model, and a translation model. In addition, the speech recognition engine 181 may include a plurality of recognition models in relation to the speech recognition operation, search for and perform an operation of the most suitable model among the respective recognition models, and perform a translation engine 182 in relation to the translation operation. It also includes a number of translation models and performs an operation by searching for the most suitable model among each translation model.

As used herein, the term 'situation condition' is a condition for determining a recognition model or a translation model used for a voice translation operation.

As described above, there are a plurality of speech recognition models in the speech recognition operation, and the speech recognition unit 181 searches a large number of speech recognition models and extracts the results in order to recognize the speech. Searching for so many speech recognition models reduces recognition accuracy as well as recognition speed. Since the mobile terminal 100 of the present invention performs a voice recognition operation by selecting a voice recognition model suitable for a specific situation condition in the voice recognition operation, the mobile terminal 100 can perform much more accurate and faster operation.

In addition, in the translation operation, there are a number of translation models. In order to perform the translation operation, numerous translation models are searched and text is analyzed. In contrast, in the translation operation, the mobile terminal 100 selects a translation model suitable for a specific situation condition and performs the translation operation, and accordingly, can perform a fast and accurate operation. For example, when it is determined that the situation condition is "company", a speech recognition model and a translation model suitable for the company may be selected to perform a voice translation operation.

There are no specific limitations on the situation condition determined by the controller 180 in connection with the present invention. For example, based on information on the user of the mobile terminal 100 or the user of the counterpart terminal, the age group, occupation group, gender, residence, etc. of the users may be determined as a situation condition. That is, since the language patterns used by the users may be different according to the age group of the user, it may be helpful to select the speech recognition model and the translation model.

4 is a flowchart illustrating the flow of a voice translation method using a mobile terminal according to the present invention.

First, the controller 180 determines a situation condition suitable for a translation operation (S410). The microphone 121 receives a user voice configured in a first language (S420). The speech recognition unit 181 included in the controller 180 recognizes the received user speech as text of a first language using the situation condition (S430). The translator 182 included in the controller 180 translates the text of the first language into the second language using the situation condition (S440). The controller 180 controls to output the translated result (S450).

5A to 5C are diagrams illustrating a translation operation using a situation condition determined according to a user's selection in relation to the present invention.

The situation condition described above may be set by the user. For example, when a user presets a situation for performing a voice translation operation before using the mobile terminal 100, the voice recognition model and the translation model may be selected according to the situation.

Referring to FIG. 5A, a screen in which a situation condition is selected by the user through the mobile terminal 100 is displayed.

In FIG. 5A (a), the display unit 151 displays to determine the age 510, the area 520 and the location 530 as the situation conditions, and the "teen" and the location information of the age information 510. “School” is indicated as selected in 530. In FIG. 5A (b), the display unit 151 informs that the "teen" and "school" are selected as the situation condition for the voice translation operation.

Referring to Fig. 5B, it is a diagram illustrating that the speech recognition engine 181 and the translation engine 182 perform the speech translation operation according to the determined situation conditions " teen " and " school. &Quot; In the speech recognition operation, the speech recognition engine 181 selects a speech recognition model related to "teen" and "school" selected as a situation condition among a plurality of speech recognition models, and analyzes and outputs the received speech as text. . In addition, in relation to the translation operation of the text, the translation engine 182 performs translation into another language using a translation model associated with "teen" and "school" selected as the context condition among a plurality of translation models.

Referring to FIG. 5C, the mobile terminal 100 displays an operation of performing a voice recognition operation in consideration of the situation conditions "teen" and "school" set by the user.

In FIG. 5C (a), the microphone 122 is voiced by the user. Receive Here, considering that the situation condition is a teenager and a school situation, the speech recognition model asks, "What's up?" Speech can be recognized as text. If it is set to 80 as a different situation condition, since the language patterns such as terms used with the teenager are different, the same voice may be recognized as different text. In (b) of FIG. 5C, the display unit 151 outputs the voice recognition result 550 to the display unit 151. Although the figure shows that the voice recognition result is output to the display unit 151, this is optional and may be omitted.

The translation engine 182 performs a translation operation on the recognized text through a translation model suitable for the situation conditions "teen" and "school". Thus, the translation engine 182 may translate the Korean text "the teacher come?" Can be translated into English translated text. Here "the teacher come?" The translation result of reflects the situation condition set by the user and may have different results in different situation conditions. Referring to (c) of FIG. 5C, the translation result 560 is output through the display unit 151. In the drawing, although it is shown as being output through the display unit 151, the translation result may be output again through the sound output module 152 or a speaker.

6A to 6C are diagrams for performing a translation operation using a situation condition determined according to user information in connection with the present invention.

The present invention may also be applied when a call is to be transmitted / received with a specific counterpart terminal through the mobile terminal 100. For example, when a user of a specific counterpart terminal is a foreigner who speaks another language, the voice of the user of the mobile terminal 100 may be translated into the language of the user of the counterpart terminal and transmitted.

The memory 160 may store various information about the user of the mobile terminal 100 or the user of the counterpart terminal in advance. Various information about the user may include a variety of information such as the user's name, the user's age, the user's occupation, the user's gender, the user's nationality, the language used by the user, the user's region, the relationship with the user. Such information may be displayed through the phone book. When the controller 180 wants to transmit / receive a call through a specific counterpart terminal and the mobile terminal 100, the controller 180 sets a condition condition using information on the user of the counterpart terminal or the user of the mobile terminal 100 to perform a voice translation operation. Applicable For example, if a user wants to talk to a specific counterpart and the age and occupation group are stored in the memory 160 as the information of the specific counterpart, the controller 180 determines the age and occupation group as the situation condition, It can be applied to speech recognition operation and translation operation.

Referring to FIG. 6A (a), an operation for selecting a specific counterpart to make a call is shown. The display unit 151 displays a phone book 610 including a plurality of counterparts. In this case, a specific person named "TOM" is set as the counterpart.

Referring to (b) of FIG. 6A, when "TOM" is set as a counterpart for making a call, information about the TOM is displayed through the display unit 151. User information about the TOM, age 30, the location is Daegu, the language used in English, the relationship with me is a company colleague, you can confirm that the gender is male. Using this user information, the speech recognition engine 181 may select a speech recognition model suitable for the user information, and the translation model 182 may select a translation model suitable for the user information.

Referring to (c) of FIG. 6A, an operation of performing a voice translation operation is illustrated. Here, the mobile terminal 100 is a process of transmitting and receiving with the TOM through the wireless communication unit 110, in which the operation of translating the voice of the TOM is performed.

Referring to FIG. 6B, the speech recognition engine 181 and the translation engine 182 diagrammatically perform a speech translation operation using user information. Since the situation condition is determined from the user information of the TOM, information of the thirties, Daegu, English, and company colleagues, which are the user information of the TOM, is used for the voice recognition operation and the translation operation, respectively. That is, in the speech recognition operation, the speech recognition engine 181 selects a speech recognition model associated with "30s", "Daegu", "English" and "company colleague" selected as a situation condition among a plurality of speech recognition models. The received voice is analyzed as text and output. In addition, in relation to the translation operation of the text, the translation engine 182 may use the translation model associated with "30s", "Daegu", "English", and "Companion" selected as contextual conditions among a number of translation models, to obtain other information. Perform a translation into the language.

Referring to FIG. 6C, the mobile terminal 100 displays an operation of performing a voice recognition operation in consideration of a situation condition set from user information.

In FIG. 6C (a), the microphone 122 has a voice from the user, "Is the work done?" Receive Here, taking into account the situational conditions from the user information, the speech recognition model can recognize the speech as text as "Are you finished?" In (b) of FIG. 6C, the display unit 151 outputs the voice recognition result 550 to the display unit 151.

The translation engine 182 performs a translation operation on the recognized text through the context condition from the user information which is the context condition. Thus, the translation engine 182 asks, "Is the job over?" Korean text called "Is the work finished?" Can be translated into English translated text. The translation result may be output again through the sound output module 152 or the speaker.

Meanwhile, the voice in which the translation operation is performed in relation to FIGS. 6A to 6C may be a user voice of the mobile terminal 100 or a voice of a call counterpart. For example, the Korean voice of the user of the mobile terminal 100 may be translated into English and transmitted to the counterpart, or the English voice of the received counterpart may be translated into Korean and transmitted to the user of the mobile terminal 100. Optionally, this translation operation may be bidirectional. That is, a translation operation on the voice of the user of the mobile terminal 100 and a translation operation on the other party's voice may be simultaneously performed.

7A to 7C are diagrams illustrating a translation operation using a situation condition determined according to location information in relation to the present invention.

The mobile terminal 100 of the present invention includes a location information module 115 capable of determining current location information of the mobile terminal 100. The location information may include accurate coordinate information of the mobile terminal 100. The controller 180 can determine the location where the mobile terminal 100 is located by using the location information. When the coordinate information is obtained from the location information module, the controller 180 can accurately grasp the place where the mobile terminal 100 is located by using a map previously stored. Therefore, the controller 180 can determine which place the mobile terminal 100 is currently located in, such as a school, an airport, a road, a company.

In general, there are differences in the language patterns used in particular places. For example, airports often use words related to the airport, such as "baggage" or "departure time", and companies may use many words related to work, such as "business" or "payment". Using a speech recognition model and a translation model suitable for a place can improve the accuracy and speed of translation.

Referring to FIG. 7A, an operation in which the controller 180 determines place information of the mobile terminal 100 or place information of the counterpart terminal 100 and selects it as a situation condition is illustrated.

Referring to FIG. 7A, the location information of the mobile terminal 100 is determined by the location information module 115, and it is determined that the current mobile terminal 100 is located at the "airport". Therefore, the controller 180 performs a voice translation operation using the "airport" as the situation condition.

Referring to FIG. 7A, it is a case where the other terminal is determined to be located in an "airport" by receiving data from the other terminal through the wireless communication unit 110. When making a call, the voice recognition model and the translation model used for the voice translation operation may be selected according to the place where the other party is located. Therefore, when the "airport" is selected as the place where the other party is located, the controller 180 may translate the other party's voice by selecting a voice recognition model and a translation model suitable for the airport as the situation condition.

Referring to FIG. 7B, the speech recognition engine 181 and the translation engine 182 diagrammatically perform a speech translation operation using location information under the conditional conditions. Since the place of the mobile terminal 100 or the place of the other party is " airport ", and a situation condition is determined therefrom, it is used for the voice recognition operation and the translation operation respectively with respect to the airport. That is, in the speech recognition operation, the speech recognition engine 181 selects a speech recognition model related to an airport selected as a situation condition from among a plurality of speech recognition models, and analyzes and outputs the received speech as text. Also, in connection with the translation operation of the text, the translation engine 182 performs translation into another language using a translation model associated with the airport selected as the context condition among a plurality of translation models.

Referring to FIG. 7C, the mobile terminal 100 displays an operation of performing a voice recognition operation in consideration of a situation condition set from place information.

In FIG. 7C (a), the microphone 122 is a voice from the user, "Where do you find the baggage?" Receive Here, taking into account the condition of the airport from the user information, the speech recognition model asks, "Where do you find your luggage?" Speech can be recognized as text. In (b) of FIG. 7C, the display unit 151 outputs the voice recognition result 770 to the display unit 151.

The translation engine 182 performs a translation operation on the recognized text through the context condition from the user information which is the context condition. Thus, the translation engine 182 asks, "Where do you find your luggage?" Korean text called "Where can I find my luggage?" Can be translated into English translated text. The translation result may be output again through the sound output module 152 or the speaker.

In connection with the above description, it has been described that both the speech recognition engine 181 and the translation engine 182 select the speech recognition model and the translation model according to the situation conditions to perform the speech recognition operation and the translation operation, respectively. However, only one of them may perform each operation according to the situation condition. 8A and 8B, there is shown an operation of determining a situation condition from the extracted result of the speech recognition engine and selecting a translation model therefrom.

The speech recognition engine 181 may analyze the input voice and output text without considering the situation condition. In the output result, a specific situation is determined from a specific word or idiom, and in consideration of the determined situation, the translation engine 182 may select a translation model.

Referring to FIG. 8A, a voice from the user asks, "Where do you find your luggage?" Consider a case of receiving 812. In this case, the speech recognition engine 181 recognizes the speech 812 in consideration of all of the plurality of speech recognition models 181a to 181x. Accordingly, when the voice is recognized as text, the controller 180 can determine from which text 814 the content of the text is generally used in the context. Here, the situation may be classified into various categories such as place, user age, user language, and the like. For example, when classified as a place, the controller 180 asks, "Where do you find your luggage?" From the term can be judged as a situation related to the airport. Although it is shown in the figure that it is determined by one airport situation, various situations may be determined from the same text content. When determined as "airport", the translation engine 182 performs a translation operation through a translation model associated with the airport, and accordingly outputs a translation result "Where can I find my luggage" 816.

8B illustrates a voice translation operation through the display unit 151 of the mobile terminal 100.

(B) of FIG. 8B is a case where voice is attracted. In Fig. 8B (b), the result of the speech recognition is displayed on the display unit 151. Here, the speech recognition engine recognizes speech as text in consideration of all of a plurality of recognition models rather than considering specific situation conditions. In Fig. 8B (c), the operation of determining the situation from the recognized text is displayed. It is the case that the airport is determined from the text 830 as the situation condition in the specific key word 832. The situation condition is determined as "airport", and the translation engine 182 performs the translation operation in consideration of this. In FIG. 8B (d), the translation result 840 is displayed on the display unit 151 as a result thereof.

The translation result translated through the translation engine 182 may be output through the sound output module 152 of the mobile terminal 100 or displayed on the display unit 151. In addition, when a call is made with the counterpart terminal, the translation result may be transmitted to the counterpart terminal through the wireless communication unit 151.

Meanwhile, an operation for checking may be additionally performed to further increase the accuracy of the translation result. Hereinafter, a confirmation method for guaranteeing a translation result will be described.

9 is a flowchart illustrating a flow of a method for checking a translation result in connection with the present invention.

As described above, the controller 180 performs a voice recognition operation and a translation operation (S910). The controller 180 outputs a translation test result as a result of the voice translation operation (S920). The controller 180 determines the adequacy of the translation test result (S930), and if not appropriate, performs the voice translation operation again. If it is determined that the result is appropriate, the controller 180 determines and outputs the translation result (S940).

A method for ensuring a translation result is described below with reference to FIGS. 10A and 10B.

First, referring to FIG. 10A, a method of providing a chance for a user to correct by translating a translated result again is illustrated.

The voice recognition engine 181 and the translation engine 182 may perform reverse translation of the corresponding translation result as a check operation for the result of completing the voice translation operation. That is, when the voice of the first language is output as the translation result of the second language, the controller 180 may inversely translate the translation result back to the first language. The reverse translated result may originally be the same as the voice of the first primary language but may differ. Thus, by providing the user with the reversed translation result, it is possible to confirm the adequacy of the translation result, thereby providing the user with an opportunity to correct the translation result.

In FIG. 10A (a), a voice “I will wait in jazz bar” 1010 is received. In FIG. 10A (b), "I'll wait on jazz" 1020 is displayed as a translation result. This translation result is again translated, and in FIG. 10A (c), "I'll wait in jazz" 1030 is displayed as the result of the reverse translation. Based on these reverse translated results, the user is provided with the opportunity to modify the translation result 1020. In FIG. 10A (d), the final result “I'll wait on jazz bar” 1033 is displayed as the modified translation result.

Referring to FIG. 10B, a method of providing all of the reverse translated candidates to the user while reversely translating the translated result is illustrated.

Similar to FIG. 10A, although the reverse translation is performed on the translation result of which the voice translation operation is completed through the speech recognition engine 181 and the translation engine 182, various candidates of the reverse translation result may be provided. Reverse translation or translation results usually have multiple candidates, but generally provide only one candidate with the highest score. However, this embodiment provides a number of candidates that are reverse translated so that the user can select them directly.

In FIG. 10B (a), the voice 1010 is received. In FIG. 10B (b), the input voice 1010 and the translation result 1020 may be displayed, and the reverse translation candidate results 1041 to 1043 for the translation result 1020 may be provided to the user. The user can select a particular candidate 1042 out of the reverse translated candidate results 1041-1043. Translation may be performed again from the particular candidate 1042 selected to provide more accurate results 1033.

On the other hand, after the speech recognition operation is finished, the translation operation may be performed after transforming the text into a more favorable form for translation. Specifically, in the language pattern, there are sentences that are identical but are recorded in different expressions. For example, "I'll wait" and "Wait" are the same, but they can be expressed differently in the Korean language, and some of these sentences may be better translated into other languages. Accordingly, when a specific text is generated as a result of the speech recognition operation, the text may be provided to the translation engine 182 by changing the text to a representation that is the same as the corresponding content but may be easier to translate.

Further, according to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
