The automatic language setting unit 10f automatically stores the language type having the highest reliability among the language types determined by the language determination unit 10b in the set language 18b.

  Next, priority setting processing for each language in the TV receiver 1 will be described with reference to the flowchart shown in FIG.

  First, immediately after the purchase of the TV receiver 1, when the user operates the remote control device 4 to turn on the power of the TV receiver 1 (S 1), the power supply unit 21 supplies power to each part of the TV receiver 1. When the power is supplied (S2), the TV receiver 1 is turned on for the first time (the TV receiver 1 is activated) (S3). And the control part 10 acquires the audio | voice input into the microphone 16 (S4).

  And the control part 10 performs a language determination process (S5) with respect to the acquired audio | voice using the speech recognition part 10a and the language determination part 10b. This language determination process is a process of determining the reliability of each language (high possibility of being in each language) based on the sound input to the microphone 16. This reliability is a value indicating how reliable the recognition result is with respect to the recognition result of the language for the voice input to the microphone 16. For example, according to the language determination process in S5, the determination result of each language is such that the reliability of “Japanese” is 90%, the reliability of “English” is 50%, and the reliability of “German” is 20%. Is output.

  Then, the control unit 10 stores the priority of each language in the priority information 18d using the priority setting unit 10c based on the determination result by the process of S5 (S6). Specifically, for example, when the reliability of “Japanese” is 90%, the reliability of “English” is 50%, and the reliability of “German” is 20%, the languages are sorted in descending order of the reliability. In addition, “Japanese” is set to priority 1, “English” is set to priority 2, and “German” is set to priority 3 and stored in priority information 18d. Here, it is assumed that the smaller the numerical value of the priority, the higher the priority. Here, an example is shown in which this processing is performed when the power of the TV receiver 1 is turned on for the first time. However, this processing may be performed every time the TV receiver 1 is activated.

  Next, the details of the language determination processing in S5 will be described with reference to the flowchart shown in FIG.

  The control unit 10 uses the voice recognition unit 10a to convert the voice signal input from the microphone 16 into a digital voice signal (S11), and further converts the digital voice signal into time-series data of feature quantity vectors. (S12).

  Then, after acquiring the multilingual dictionary data 18c (S13), the control unit 10 uses the language determination unit 10b to store the data of each language of the multilingual dictionary data 18c and the time series of the feature vector of S12. The data is collated (S14). And the control part 10 outputs the determination result of each language based on this collation result using the language determination part 10b (S15). The determination result output here is reliability information based on the collation result in S14, for example, the reliability of “Japanese” is 90% and the reliability of “English” is 50%.

  Next, an example of language setting processing in the TV receiver 1 will be described with reference to the flowchart shown in FIG.

  First, when display of the language setting screen is instructed by the user operating the remote control device 4 (S21), the control unit 10 uses the language setting screen display unit 10d based on the content of the priority information 18d. Then, a language list in which the types of languages are arranged in ascending order of priority values from the language type with priority 1 is generated (S22), and a language setting screen including the generated language list is displayed on the display 14 (S22). S23). Here, it is assumed that the smaller the numerical value of the priority, the higher the priority. That is, in the language list, the types of languages having high priority are rearranged and displayed at the top as candidates for the types of languages that can be set.

  When the user selects a desired language type from the language list (S24), the control unit 10 stores the selected language type in the set language 18b (S25).

  FIG. 6 shows an example of the language setting screen displayed on the display 14 in S23. Symbol L1 indicates a language list. The language list shown in FIG. 6 shows a case where priority is high as a settable language type candidate in the order of “Japanese”, “English”, “Dansk”, “Deutsch”, “Eesti”. That is, in this language list L1, “Japanese” having the highest priority is displayed at the top of the language list L1. When the user wants to select “Japanese”, the user simply sets the language type as “Language” by simply pressing the determination button of the remote control device 4 without moving the cursor C (corresponding to S24 above). (Corresponding to S25 above).

  FIG. 7 shows another example of the language setting screen displayed on the display 14 in S23. Symbol L2 indicates a language list. The language list shown in FIG. 7 indicates a case where priority is high as a settable language type candidate in the order of “Italiano”, “Espa ñ ol”, and “Fran ç ais”. That is, in this language list L2, “Italiano” having the highest priority is displayed at the top of the language list L2. When the user wants to select “Italiano”, the user can set “Italiano” as the language type by simply pressing the enter button of the remote control device 4 without moving the cursor C (corresponding to S24). (Equivalent to S25 above).

  Next, another example of the priority setting process will be described with reference to the flowchart shown in FIG. First, when the user instructs the all setting reset (initialization) by operating the remote control device 4 (S31), the control unit 10 uses the setting initialization unit 10e, and the contents of the setting language 18b of the memory 18; The contents of the priority information 18d and the contents of the various setting information 18e are deleted (S32).

  And the control part 10 acquires the audio | voice input into the microphone 16 using the audio | voice recognition part 10a (S33), and performs a language determination process (S34) based on the acquired audio | voice. Based on the determination result, the control unit 10 stores the priority of each language in the priority information 18d using the priority setting unit 10c (S35). The language determination process in S34 is the same as the process in FIG.

  Next, another example of the priority setting process will be described with reference to the flowchart shown in FIG. S41 to S45 of this process are the same as S1 to S5 of the language setting process shown in FIG.

  After the language determination process in S45, the control unit 10 is determined to have the highest priority as a settable language type candidate based on the determination result of the language determination process using the automatic language setting unit 10f. The language type is stored in the set language 18b (S46). That is, the control unit 10 automatically sets the language type using the automatic language setting unit 10f.

  As described above, according to the TV receiver 1 according to the present embodiment, the control unit 10 is input using the voice recognition unit 10a and the language determination unit 10b based on the voice input to the microphone 16. The type of speech language corresponding to the speech signal is determined. Therefore, for example, in a language list including a large number of language types, based on the determination result, a language type with high reliability (highly likely to be each language) is selected as a language type candidate. It can be displayed at the top. As a result, the user can easily set the desired language type simply by selecting the language type displayed at the top of the language list. Therefore, since the user can set the desired language type with a small number of operations, the effort for setting the desired language type can be reduced.

  In the TV receiver 1, as shown in FIG. 3, when the user turns on the power for the first time immediately after the purchase of the TV receiver 1, each language is based on the sound input to the microphone 16. The priority is stored in the priority information 18d. Therefore, when the user displays the language setting screen, a language list based on the content of the priority information 18d is displayed on the language setting screen. Therefore, even when the language setting screen is displayed for the first time immediately after the purchase of the TV receiver 1, the user can easily select the desired language type simply by selecting the language type displayed at the top of the language list. Therefore, it is possible to set a desired language type with a small number of operations, and it is possible to reduce time and labor when setting the desired language type. Further, each time the TV receiver 1 is activated, the processing may be performed as shown in FIG.

  In the TV receiver 1, as shown in FIG. 8, the priority of each language is given priority based on the sound input to the microphone 16 when the user instructs the all setting reset (initialization). It is stored in the degree information 18d. Therefore, when the user displays the language setting screen after resetting all settings, the language setting screen displays a language list based on the content of the priority information 18d in which the priority of each language is stored. Therefore, even when the language setting screen is displayed after resetting all settings, the user can easily set the desired language type simply by selecting the language type displayed at the top of the language list. Therefore, it is possible to set a desired language type with a small number of operations, and it is possible to reduce time and labor when setting the desired language type.

  In the TV receiver 1, as shown in FIG. 9, the control unit 10 is input using the voice recognition unit 10 a and the language determination unit 10 b based on the voice input to the microphone 16. The speech language type is determined, and the language type with the highest priority is automatically stored in the set language 18b as a language type candidate. Therefore, the user does not have to search for and manually set a desired language type from among a plurality of language types, so that the language type can be easily set.
