The voice information acquisition unit 10 uses, for example, a microphone and acquires the voice as it is as voice information.
The audio information acquisition unit 10 is not limited to acquiring audio as it is, but may be designed to acquire the audio signal as audio information after the audio is converted into an audio signal.

  The remote control signal light receiving unit 11 receives an input operation signal such as an infrared ray that is output when various keys provided on the remote control 2 are pressed by the user, and outputs the input operation signal to the control unit 12.

  For example, as shown in FIG. 1, the control unit 12 includes a CPU (Central Processing Unit) 121, a RAM (Random Access Memory) 122, a storage unit 123, and the like.

  The CPU 121 performs various control operations according to the command table and various processing programs stored in the storage unit 123.

  The RAM 122 includes a program storage area for expanding a processing program executed by the CPU 121, a data storage area for storing input data, a processing result generated when the processing program is executed, and the like.

The storage unit 123 stores a system program that can be executed by the device main unit 1, various processing programs that can be executed by the system program, data that is used when these various processing programs are executed, and processing results that are calculated by the CPU 121. Store data etc. Note that the program is stored in the storage unit 123 in the form of a computer-readable program code.
Specifically, the storage unit 123 stores control command information extracted by the CPU 121 executing a command information extraction program 123c described later.
The storage unit 123 functions as a control command information storage unit by storing such control command information.
Further, as shown in FIG. 1, for example, a command table 123a, a voice recognition program 123b, a command information extraction program 123c, a discrimination program 123d, a calculation program 123e, a control program 123f, and the like are stored in the storage unit 123.

The command table 123a includes control command information for controlling the device body 1, repetitive command information for repeatedly executing control based on the control command information, and stop command information for stopping control repeatedly executed based on the repetitive command information. Is a table storing
Specifically, as shown in FIG. 2, for example, “ON”, “OFF”, “CHANNEL UP”, “VOLUME UP”, etc. are stored as control command information, and the CPU 121 determines a determination program described later. When executing 123d, it is stored in such a manner that it can be identified whether or not it is preset control command information to be repeated.
In addition, “more”, “much”, “one”, “two”, “three”, etc. are stored as repeated command information, and repeated command information “more”, “one”, “two”, “three” The number of repetitions is set in advance, and the repetition command information “all” is set to be repeated endlessly. The number of repetitions may be designed so that the user can change the setting.
In addition, “stop” or the like is stored as stop command information.

The command table may be designed to store the control command information, the repeat command information, and the cancel command information separately as a control command table, a repeat command table, and a stop command table.

The voice recognition program 123b is a program that causes the CPU 121 to realize a function of performing voice recognition processing on the voice information acquired by the voice information acquisition unit 10.
Here, speech recognition is realized by, for example, using Julius speech recognition software and accumulating enormous speech patterns and language pattern statistical data. The basic principle of speech recognition is to store the frequency pattern of an acoustic model (phoneme (equivalent to one Roman letter) or syllable (equivalent to one kana character)), and refer to the word dictionary while referring to the word dictionary. It performs matching with the syllable string signal obtained by cutting out a single syllable part from the signal and recognizes the voice.

The command information extraction program 123c is a program that causes the CPU 121 to realize a function of extracting command information that matches a word string obtained by executing the speech recognition program 123b from the command table 123a.
Specifically, by executing the command information extraction program 123c, for example, when the word string “channel up” is acquired as a voice recognition result, the CPU 121 stores it in the command table 123a as shown in FIG. The control command information “channel up” is extracted.
The CPU 121 functions as a command information extraction unit by executing the command information extraction program 123c.

When the repetitive command information is extracted after the control command information by executing the command information extracting program 123c in the CPU 121, the determination program 123d determines whether the latest control command information is the control command information to be repeated. It is a program that realizes a function of determining whether or not.
Specifically, when the CPU 121 executes the command information extraction program 123c to repeatedly extract command information, the CPU 121 executes the determination program 123d to thereby execute the latest control command stored in the storage unit 123. It is determined whether the information is preset control command information to be repeated. More specifically, for example, as shown in FIG. 2, when the latest control command information stored in the storage unit 123 is “channel up”, the CPU 121 executes the determination program 123 d to thereby execute the control command. It is determined that the information is control command information to be repeated. When the most recent control command information stored in the storage unit 123 is “ON”, the CPU 121 determines that the control command information is not the control command information to be repeated by executing the determination program 123d.
The CPU 121 functions as a determination unit by executing the determination program 123d.

The calculation program 123e is a program that causes the CPU 121 to realize a function of calculating the number of repetitions based on the length of a long note following the end of the word string obtained by executing the speech recognition program 123b.
Specifically, for example, when the user utters with the word “channel up-oo” extended, the CPU 121 executes the calculation program 123e, whereby the word string “channel” obtained by the execution of the speech recognition program 123b. Based on "up--", the time length of the long note "---" following the ending of "channel up" is measured, and the number of repetitions is calculated according to the time length.
The CPU 121 functions as a calculation unit by executing the calculation program 123e.

The control program 123f is a program that causes the CPU 121 to execute a command information extraction program 123c to realize a function of repeatedly performing control based on the control command information when repeated command information is extracted following the control command information. .
Specifically, when the CPU 121 executes the determination program 123c, it is determined that the most recent control command information stored in the storage unit 123 is preset control command information to be repeated, and the command information extraction program When the time when the command information is repeatedly extracted by the execution of 123c is within a predetermined time after the latest control command information is stored in the storage unit 123, the CPU 121 extracts the command information by executing the control program 123f. The control based on the latest control command information stored in the storage unit 123 is repeatedly performed until the cancel command information is extracted by executing the program 123c.
The CPU 121 functions as a control unit by executing the control program 123f.

  In step S6, if the command information is repeatedly extracted by the CPU 121 executing the command information extraction program 123c (step S6; Yes), the process proceeds to step 7. On the other hand, when the CPU 121 executes the command information extraction program 123c in step S6 and the command information is not repeatedly extracted (step S6; No), the process skips steps S7 to S9 and proceeds to step S10.

On the other hand, when it is determined in step S7 that the control command information stored in the storage unit 123 is not the control command information to be repeated by the CPU 121 executing the determination program 123d (step S7; No), Step S9 is skipped and the process proceeds to step S10.

  Subsequently, in step S8, the CPU 121 repeatedly stores the command information “channel up” in the storage unit 123 for the time when the CPU 121 repeatedly extracted the command information “more” by executing the command information extraction program 123c. To determine whether it is within a predetermined time.

  In step S8, the time when the CPU 121 repeatedly extracts the command information “more” by executing the command information extraction program 123c is within a predetermined time after the latest control command information “channel up” is stored in the storage unit 123. When it is determined that there is (step S8; Yes), the process proceeds to step S9. On the other hand, in step S8, the time when the CPU 121 repeatedly extracts the command information “more” by executing the command information extraction program 123c is a predetermined time after the latest control command information “channel up” is stored in the storage unit 123. When it is determined that it is not within (step S8; No), step S9 is skipped and the process proceeds to step S10.

Next, in step S9, the CPU 121 repeatedly executes control based on the control command information “channel up” by executing the control program 123f.
In such a case, the control based on the control command information “channel up” is repeatedly executed as many times as preset in the repeat command information “more”.

  Next, in step S10, the CPU 121 executes the command information extraction program 123c to extract stop command information from the voice recognition result.

  In step S10, when the CPU 121 executes the command information extraction program 123c and no stop command information is extracted (step S10; No), the process proceeds to step S11. On the other hand, when the CPU 121 executes the command information extraction program 123c to extract stop command information (step S10; Yes), the process proceeds to step 12.

  Next, in step S11, the CPU 121 determines whether or not the control based on the control command information has ended. If it is determined that the control based on the control command information has ended (step S11; Yes), the process ends. To do. On the other hand, when it is determined in step S11 that the control based on the control command information has not ended (step S11; No), the process returns to step S10. Here, the description has been made on the premise that the repetitive command information that is repeated a preset number of times is extracted, and the control is performed a preset number of times, but the repetitive command information that is repeatedly executed in an endless manner is extracted. If YES in step S11, step S11 is omitted, and if stop command information is not extracted in step S10 (step S10; No), the process returns to step 10 repeatedly. On the other hand, when the CPU 121 executes the command information extraction program 123c to extract stop command information (step S10; Yes), the process proceeds to step 12.

  Next, in step S12, the CPU 121 executes the control program 123f to stop the control being repeatedly executed based on the stop command information extracted by the CPU 121 executing the command information extraction program 123c. This process ends.

  If the CPU 121 determines in step S21 that the audio information acquisition unit 10 has acquired the audio information “for example, channel up—” (step S21; Yes), the process proceeds to step S22. On the other hand, when the CPU 121 determines in step S21 that the voice information acquisition unit 10 has not acquired voice information (step S21; No), the voice information acquisition standby state is repeated.

  Next, in step S22, the CPU 121 executes the voice recognition program 123b to perform voice recognition of the voice information “channel up--” acquired by the voice information acquisition unit 10, and proceeds to step S23.

  Next, in step S23, the CPU 121 executes the command information extraction program 123c to extract the control command information “channel up” from “channel up” obtained as a result of speech recognition.

In step S23, when the control command information is extracted by the CPU 121 executing the command information extraction program 123c (step S23; Yes), the process proceeds to step S24. On the other hand, in step S23, when the control command information is not extracted by the CPU 121 executing the command information extraction program 123c (step S23; No), this process ends.

This process is terminated according to the number of repetitions calculated by the above.

According to the digital television receiver 100 according to the present invention described above, the control command information for controlling the device main unit 1 and the repetitive command for repeatedly executing the control based on the control command information endlessly by the command table 123a. The information and the stop command information for stopping the control repeatedly executed by the repeated command information can be stored, the voice information can be acquired by the voice information acquisition unit 10, and the CPU 121 executes the command information extraction program 123c. By performing the voice recognition of the voice information acquired by the voice information acquisition unit 10, it is possible to extract any of the control command information, the repeated command information, and the stop command information stored in the command table 123a, According to the storage unit 123 Thus, the control command information extracted by the CPU 121 executing the command information extraction program 123c can be stored, and if the command information is repeatedly extracted by the CPU 121 executing the command information extraction program 123c, the CPU 121 By executing the determination program 123d, it is possible to determine whether or not the latest control command information stored in the storage unit 123 is preset control command information to be repeated. Is executed, it is determined that the most recent control command information stored in the storage unit 123 is preset control command information to be repeated, and the CPU 121 executes the command information extraction program 123c to repeatedly execute the command. When the time when the command information is extracted is within a predetermined time after the latest control command information is stored in the storage unit 123, the CPU 121 executes the control program 123f, whereby the CPU 121 executes the command information extraction program 123c. Thus, the control based on the latest control command information stored in the storage unit 123 can be repeatedly performed until the cancel command information is extracted.
Therefore, when repeatedly executing the control based on the control command information, the control based on the control command information can be repeatedly executed by uttering the repeated command information without repeating the control command information. Convenient for users.
In addition, it is possible to determine whether or not the control command information is a preset repetition target control command, and thus it is possible to suitably prevent repetitive control that is not intended by the user.
In addition, if the repetitive command information is not extracted within a predetermined time after the most recent control command information is stored, the control based on the control command information is not repeatedly performed. When the same voice information as the repeated command information is acquired, it is possible to more suitably prevent the repeated control not intended by the user.
Furthermore, when the stop command information is input while the control based on the control command information is repeatedly performed, the repeated control can be stopped, which is more convenient for the user.

The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, voice recognition is a design that performs voice recognition of voice information using an acoustic model pattern related to a frequency pattern of a voice signal suitable for each user, which is associated with each user and stored in advance in a storage unit. Also good.
Further, the repetitive command information may be designed so that it can be customized by voice input or key input in a user-friendly manner, and new repetitive command information can be registered.
Further, the predetermined time for determining whether or not the time when the command information extraction means repeatedly extracts command information is within a predetermined time since the most recent control command information is stored in the control command information storage means is: The design can be changed by the user.
