  The dictionary (1) 107 and the dictionary (2) 108 are each composed of a nonvolatile memory such as a flash memory. FIG. 2 is a diagram showing an example of data stored in the dictionary (1) 107, and is composed of data of “name” and “phone number” of a person who has registered voice dialing from the telephone directory of the mobile phone 10. The name data includes both “reading” (for example, “Matsushita Taro”, “John Wayne”, etc.) and “display characters” (for example, “Taro Matsushita”, “John Wayne”, etc.). FIG. 3 is a diagram showing an example of data stored in the dictionary (2) 108. In addition to data similar to the dictionary (1) 107, each of “voice search”, “voice setting”, and “camera operation” is shown. It is composed of data and data corresponding to “how to use”, “speech recognition setting”, and “camera operation”. “Voice Search”, “Voice Setting”, and “Camera Operation” each include both “reading” and “displayed characters”.

  Dictionary (1) 107 is selected when the case of mobile phone 10 is closed, and dictionary (2) 108 is selected when the case of mobile phone 10 is open. That is, when the casing of the mobile phone 10 is in the open state, all the functions of “voice dial”, “voice search”, “voice setting”, and “camera operation” are enabled, but the casing of the mobile phone 10 is closed. When in the state, only the “voice dial” function is enabled.

  The case open / close detection unit 105 detects the open / close state of the case of the mobile phone 10, but the detection may be performed mechanically or electrically. As a mechanical detection, for example, there is a method using a push button switch. In this case, the push button switch main body is fixed to one of the two casings, and the movable part of the push button switch hits the other of the two casings. As a result, when the casing is closed, the movable part of the push button switch is pushed into the main body and turned on (or off), and when the casing is opened, the movable part of the push button switch is opened and turned off (or on). It becomes. On the other hand, as an electrical detection, for example, there is a method using a photosensor including a light emitting element and a light receiving element. In this case, the light emitting element and the light receiving element are configured to be blocked according to the opening / closing of the housing. Thereby, when the casing is closed, the output of the light receiving element becomes H (or L), and when the casing is opened, the output of the light receiving element becomes L (or H).

  The portable terminal control unit 115 activates the voice recognition unit 106 by receiving a voice recognition start request from the headset 20 via the Bluetooth wireless transmission / reception unit 103. Here, in the present embodiment, HFP (Hands Free Profile) is used for communication between the mobile phone 10 and the headset 20. This HFP is a profile for realizing hands-free calling in a vehicle or in a headset. Both the mobile phone 10 and the headset 20 have this HFP. As is well known, Bluetooth uses a 2.4 GHz frequency band and performs wireless communication at a maximum of 3 Mbps between Bluetooth-equipped devices within a radius of about 10 to 100 m.

  From the headset 20, a command of HFP AT + BVRA = “1” is transmitted to the mobile phone 10 when a voice recognition start request is made. Here, the AT + BVRA command is a command meaning “Enables or Disables voice recognition in the AG (Audio Gateway)”. That is, this is a command for instructing whether or not voice recognition is permitted in AG. When voice recognition is turned off (cancelled), a command of AT + BVRA = “0” is transmitted from the headset 20 to the mobile phone 10.

  When the cellular phone control unit 115 receives the command of AT + BVRA = “1” transmitted from the headset 20 via the Bluetooth wireless transmission / reception unit 103, the cellular phone control unit 115 activates the voice recognition unit 106. After the voice recognition unit 106 is activated, the voice recognition function of the voice recognition unit 106 is used to detect the opening / closing state of the two cases. One function is selected from the four functions of “voice dial”, “voice search”, “voice setting”, and “camera operation” according to the audio signal. In this case, if the housing is in the open state, the mobile phone control unit 115 causes the headset 20 to make a sound out of the four functions of “voice dial”, “voice search”, “voice setting”, and “camera operation”. Select the entered function. That is, when a voice signal specifying the “voice dial” function is input, the “voice dial” function is selected. When a voice signal specifying the “voice search” function is input, the “voice search” function is selected. When the audio signal specifying the “Voice setting” function is input, the “Voice setting” function is selected. When the audio signal specifying the “Camera operation” function is input, the “Camera operation” function is selected. To do. On the other hand, if the housing is in the closed state, the cellular phone control unit 115 selects only the “voice dial” function, and therefore, “voice dial” only when an audio signal designating the “voice dial” function is input. Select a function.

  In addition, when the casing is in a closed state as a detection result of the casing opening / closing detection unit 105, the mobile phone control unit 115 instructs the voice recognition unit 106 to use the dictionary (1) 107, and the casing If is in the open state, the voice recognition unit 106 is instructed to use the dictionary (2) 108. The cellular phone control unit 115 controls the voice recognition unit 106 using the dictionary (1) 107 or the dictionary (2) 108. That is, if the case is opened as a result of detection by the case opening / closing detection unit 105, the “voice dial”, “voice search”, “voice setting”, and “camera operation” functions of the own device are included. The function called by the headset 20 is selected, and the voice recognition unit 106 is controlled using the dictionary (2) 108 in which data for achieving the selected function is stored, while the casing is closed. If so, the “voice dial” function of the device itself is selected, and the voice recognition unit 106 is controlled using the dictionary (1) 107 in which data for achieving the “voice dial” function is stored. To do.

  The headset 20 is transmitted from the mobile phone 10 through Bluetooth communication with the mobile phone 10 via a Bluetooth wireless transmission / reception unit 201, an antenna 202 connected to the Bluetooth wireless transmission / reception unit 201, and wireless communication using Bluetooth. A speaker 203 for outputting a voice signal, an input button 204 for starting and canceling the voice recognition function of the mobile phone 10, a microphone 205 for inputting a user's voice, and each part of the headset 20. A headset control unit 206.

  When the headset control unit 206 detects that the input button 204 is pressed, the headset control unit 206 transmits a voice recognition start request to the mobile phone 10 via the Bluetooth wireless transmission / reception unit 201. In this case, as described above, the HFP AT + BVRA = “1” command is transmitted. Further, when the headset control unit 206 detects that the input button 204 is further pressed, the headset control unit 206 transmits a voice recognition end request to the mobile phone 10 via the Bluetooth wireless transmission / reception unit 201. In this case, as described above, the HFP AT + BVRA = “0” command is transmitted.

  Next, the operation of the wireless communication system 1 according to the present embodiment will be described with reference to the flowchart shown in FIG. In FIG. 4, in the headset 20, when the user presses the input button 204, the headset control unit 206 detects this and transmits a command of AT + BVRA = “1” from the Bluetooth wireless transmission / reception unit 201 to the mobile phone 10. (Step ST1). Next, when there is an audio input from the headset 20, the audio data is transmitted from the Bluetooth wireless transmission / reception unit 201 to the mobile phone 10 (step ST2).

  In the mobile phone 10, when the Bluetooth wireless transceiver 103 receives the AT + BVRA = “1” command transmitted from the headset 20, the mobile phone controller 115 establishes an HFP wireless link with the headset 20. Perform the process. After the wireless link by HFP is established with the headset 20, the mobile phone control unit 115 detects the open / close state of the case of the mobile phone 10 as a detection result of the case open / close detection unit 105 (step ST3). It is determined whether the casing state of the mobile phone 10 is open or closed (step ST4). If it is open, using the dictionary (2) 108, "voice dial", "voice search", "voice setting", and "camera" Of the four functions “operation”, the one designated by voice input from the headset 20 is selected, and voice recognition is performed for the selected function (step ST5). And the guide (guidance) message corresponding to voice recognition is displayed on the display part 110 (step ST6). On the other hand, if the housing state of the mobile phone 10 is closed, the dictionary (1) 107 is used to select the “voice dial” function by voice input from the headset 20, and the selected “voice dial” function is voiced. Recognition is performed (step ST7). At this time, the voice guidance data is transmitted from the cellular phone 10 to the headset 20 and output from the speaker 203 of the headset 20 regardless of whether the casing of the cellular phone 10 is open or closed. (Step ST8).

  For example, when the “voice dial” function is selected, when the user utters “Matsushita Taro” toward the microphone 205 of the headset 20, the voice recognition unit 106 of the mobile phone 10 recognizes the voice and enters the housing state. Accordingly, if the data of the display character “Taro Matsushita” corresponding to the reading “Matsushita Taro” stored in the dictionary (2) 108 or the dictionary (1) 107 is read and the housing state is open, Is displayed on the display unit 110. Then, automatic transmission to the telephone number (090-xxxxxxxx) of “Taro Matsushita” is performed by the “voice dial” function. The “telephone number” at this time is transmitted to the headset 20 as voice guidance, and is output from the speaker 203 of the headset 20 as voice.

  In addition, when the housing state is open and the user utters “voice voice” toward the microphone 205 of the headset 20, the voice is recognized by the voice recognition unit 106 of the mobile phone 10 and stored in the dictionary (2) 108. The data of the display character “How to use” corresponding to the reading “Voice Kensaku” is read and displayed on the display unit 110. Then, a process of searching for a function that the user wants to search is performed by the “voice search” function. As described above, there are a camera, a clock and the like as a function to be searched for. The “how-to-use guidance” at this time is transmitted to the headset 20 as voice guidance and is output as voice from the speaker 203 of the headset 20.

  Further, when the housing state is open and the user utters “voice setting” toward the microphone 205 of the headset 20, the voice recognition unit 106 of the mobile phone 10 recognizes the voice and saves it in the dictionary (2) 108. The data of the display character “speech recognition setting” corresponding to the reading “voice setting” is read and displayed on the display unit 110. Then, settings related to voice dialing are performed by the “voice setting” function. As described above, the voice dial related settings include automatic voice dial transmission and automatic voice transmission. The “voice recognition setting” at this time is transmitted to the headset 20 as voice guidance and is output from the speaker 203 of the headset 20 as voice.

  Further, when the housing state is open and the user utters “camera sous” toward the microphone 205 of the headset 20, the voice recognition unit 106 of the mobile phone 10 recognizes the voice and saves it in the dictionary (2) 108. The data of the display character “camera operation” corresponding to the reading “camera sousa” is read and displayed on the display unit 110. Then, the camera operation is performed by the “camera operation” function. The “camera operation” at this time is transmitted to the headset 20 as voice guidance and is output from the speaker 203 of the headset 20 as voice.

  Thereafter, when the casing state of the mobile phone 10 is closed, only the voice call by HFP is performed between the mobile phone 10 and the headset 20. That is, when the housing state is closed, since only the “voice dial” function is used, the voice from the mobile phone (including the fixed phone) of the communication partner connected by automatic transmission is transmitted from the mobile phone 10 to the headset. The voice that the user of the mobile phone 10 talks to the microphone 205 of the headset 20 is transmitted from the headset 20 to the mobile phone 10. On the other hand, when the housing state of the mobile phone 10 is open, other communication is performed between the mobile phone 10 and the headset 20 in addition to the voice call by HFP.

  As described above, according to the wireless communication system 1 of the present embodiment, when the mobile phone 10 communicates with the headset 20 wirelessly, and there is a voice recognition start request from the headset 20, the request is accepted. The voice recognition unit 106 is activated. If the case is opened when the open / closed state of the case is detected, the head of the “voice dial”, “voice search”, “voice setting”, and “camera operation” functions of the device itself The function designated on the set 20 side is selected, and the voice recognition unit 106 is controlled using the dictionary (2) 108 in which data for achieving the selected function is stored, while the case is closed. If so, the “voice dial” function of the device itself is selected, and the voice recognition unit 106 is controlled using the dictionary (1) 107 in which data for achieving the “voice dial” function is stored. Thereby, even if the housing of the mobile phone 10 is in a closed state, it can be used.

  In this embodiment, two dictionaries (1) 107 and dictionaries (2) 108 are used, but they can be combined into one. FIG. 5 is a diagram showing an example of data stored in the dictionary 120 in which the contents of the dictionary (1) 107 and the contents of the dictionary (2) 108 are combined. In the dictionary 120, the contents of the dictionary (1) 107 and the contents of the dictionary (2) 108 can be identified by flag bits FLAG. That is, when the casing of the mobile phone 10 is in the closed state, only data specified by the flag bit “11” is handled, and when the casing of the mobile phone 10 is in the open state, the flag bits “11” and “10” are handled. ”Is specified. By combining the two dictionaries (1) 107 and the dictionary (2) 108 into one, the cost can be reduced and the mobile phone 10 can be downsized.

  In this embodiment, the input button 204 of the headset 20 is used to make a voice recognition start request and a voice recognition end request. However, the input button 204 can also be used to cancel a voice recognition error. It is. For example, a cancel request is output by pressing the input button 204 for 1 second or longer. In this way, when the user of the mobile phone 10 searches for an undesired person, for example, the user can cancel by simply pressing the input button 204 of the headset 20 without performing a keypad operation. .

  In this embodiment, the pop-up (POPUP) screen when the casing of the mobile phone 10 is closed has not been described. However, the pop-up screen is not displayed when the casing of the mobile phone 10 is closed. The pop-up content may be listened to by the headset 20 as voice guidance.

  In this embodiment, if the housing is in an open state, one function is selected from the four functions of “voice dial”, “voice search”, “voice setting”, and “camera operation”. However, it is also possible to select one function from the three functions of “voice dial”, “voice search”, and “voice setting”.

  In the present embodiment, Bluetooth has been described as wireless communication performed between an external device and a mobile terminal. However, other wireless communication such as WLAN is possible.

  In the present embodiment, the mobile phone 10 is a foldable mobile terminal having two openable / closable casings. However, the mobile phone 10 can be opened and closed by sliding the two casings relative to each other. A slide-type portable terminal may be used. Furthermore, other types of portable terminals may be used as long as they can be opened and closed with two housings.

  Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.

  The present invention can be used even when the casing of the mobile terminal is closed, and can be used comfortably even if the mobile terminal is housed in an object separated from a human body such as a bag. Has the effect of reducing misrecognition when used with the body closed, has a voice recognition function, and can be applied to mobile devices that are wirelessly connected to external devices such as headsets. It is.
