  In the loudspeaker 1, as shown in FIG. 7, first, if the mode switch 12 is not in the translation mode, that is, in the megaphone mode (No in ST101), the voice switching unit 5 is received by the microphone 3. When the output switch 16 is pressed (Yes in ST102), the amplifier 7 enters a sound output state and starts outputting the original sound (ST103). At this time, the original voice spoken by the user is directly amplified by the amplifier 7 and output from the speaker 8. When the output switch 16 is returned (Yes in ST104), the output of the original voice is stopped (ST105). When the output switch 16 is not pressed (No in ST102), no special operation is performed.

  On the other hand, when the mode switch 12 is in the translation mode (Yes in ST101), it is next determined in the operation detection unit 31 whether or not the recording switch 14 is pressed (ST106). If the recording switch 14 is pressed (Yes in ST106), the display input panel 9 is turned on in the power saving control unit 39 (ST107). Then, the operation detection unit 31 determines whether or not the operation of the recording switch 14 is a long press (ST108).

  Here, when the operation of the recording switch 14 is a long press (Yes in ST108), the recording unit 32 starts a process of recording the original voice collected by the microphone 3 (ST109). At this time, the user may be notified of the start of recording by vibration or notification sound. When the recording switch 14 is returned (Yes in ST110), recording is stopped (ST111).

  Next, the voice recognition unit 33 performs voice recognition for converting the recorded original voice into character information (ST112). Next, the search unit 34 performs a search for searching for a fixed phrase similar to the original sentence (character information of the original voice) (ST113). Then, a fixed phrase display screen (see FIG. 6) for displaying the fixed phrases found by the search unit 34 is displayed on the display input panel 9 (ST114). And it progresses to the audio | voice output process (ST127 or later) shown in FIG.

  On the other hand, when the operation of the recording switch 14 is not a long press (No in ST108), as shown in FIG. 8, next, in the operation detection unit 31, whether or not the operation of the recording switch 14 is a single short press. Is determined (ST115). Here, in the case of one short press (Yes in ST115), next, in the screen control unit 38, whether or not the currently displayed screen is one of a plurality of continuous screens (pages). Is determined (ST116). Here, when the currently displayed screen is one of the continuous screens, specifically, when the screen is a fixed phrase display screen (see FIG. 6) (Yes in ST116), the next screen (page ) Is determined (ST117). If there is a next screen (Yes in ST117), the screen is switched to the next screen (ST118). When there is no next screen (No in ST117), no special operation is performed.

  In addition, when the currently displayed screen is not one of the continuous screens, specifically, when the screen is a standard text list screen (see FIG. 4) (No in ST116), next candidate (standard text) It is determined whether or not there is (ST119). If there is a next candidate (Yes in ST119), the next candidate is selected (ST120). At this time, if the last candidate is selected, the first candidate is changed to the selected state. When there is no next candidate (No in ST119), no special operation is performed.

  On the other hand, if the operation of the recording switch 14 is not a single short press (No in ST115), the operation detection unit 31 then determines whether or not it is a short press (ST121). Here, in the case of two short presses (Yes in ST121), the screen control unit 38 then determines whether the currently displayed screen is one of the continuous screens (ST122). Here, when the currently displayed screen is one of the continuous screens, specifically, when the screen is a fixed phrase display screen (see FIG. 6) (Yes in ST122), then the previous screen (page ) Is determined (ST123). If there is a previous screen (Yes in ST123), the screen is switched to the previous screen (ST124). When there is no previous screen (No in ST123), no special operation is performed.

  If it is not a continuous screen, specifically, if it is a fixed phrase list screen (see FIG. 4) (No in ST122), then whether there is a selected fixed phrase candidate (fixed sentence) or not. Is determined (ST125). Here, if there is a candidate being selected (Yes in ST125), the candidate is selected (ST126). Thereby, it changes to a fixed text display screen (refer to Drawing 5). When there is no candidate being selected (No in ST125), no special operation is performed.

  On the other hand, as shown in FIG. 7, when the recording switch 14 has not been pressed (No in ST106), the process proceeds to the audio output process (after ST127) shown in FIG. In this case, when the user operates the display input panel 9, a fixed phrase for performing voice output is selected without operating the recording switch 14.

  As shown in FIG. 9, in the audio output process, first, in the operation detection unit 31, it is determined whether or not the output switch 16 is pressed (ST127).
