Embodiment 1 FIG.
FIG. 1 is a block diagram showing Embodiment 1 of a portable information terminal equipped with a call voice recording function and a voice recognition function of the present invention.
In FIG. 1, the communication control / processing unit 1 controls connection to a number partner input to the dial unit 2 via the telephone line 3, sends the input voice from the microphone 4 to the telephone line 3, and the telephone line. The voice of the other party from 3 is output to the speaker 5. Further, based on the instruction signal, the voice recognition processing of the calling side voice and the voice of the other party (both are referred to as calling voice) and the voice text processing of the recognition result are performed. The call voice storage means 6 records the call voice for each call by a designation signal by operating the recording button 7 and the stop button 8. The call text storage means 9 stores the result of converting the call voice recorded in the call voice storage means into text by the communication control / processing means 1. The communication control / processing unit 1 stores call information such as the telephone number and time of the other party in the call history storage unit 10 for each call. Then, the association unit 11 associates the call voice storage unit 6 and the call text stored in the call text storage unit 9 based on the call information stored in the call history storage unit 10. The display means 12 displays the call information saved by the call history display button 13, the saved call information, and the saved call voice in association with each other. The operation means 14 selects the contents displayed on the display means and performs operations such as reproduction of call voice and display of call text.

  Next, the operation will be outlined with reference to FIG. The communication control / processing unit 1 establishes a call by establishing a call to the telephone number input from the dial unit 2 or processing an incoming call from the other party. The voice of the speaker is transmitted from the microphone 4 to the telephone line 3 by the communication control / processing means 1, and the voice of the communication partner from the telephone line 3 is sent from the communication control / processing means 1 to the speaker 5 and output as voice. . When the recording button 7 is pressed in a state where the call is established in this way (hereinafter referred to as “calling”), the communication control / processing unit 1 starts to capture the voice during the call and stores the voice as the call voice. When it is stored in the means 6 and the stop button 8 is pressed, the storage in the call voice storage means 6 is stopped. Further, the communication control / processing unit 1 assigns the call history ID to the call information such as the telephone number of the call partner and the call start time and stores the call history ID in the call history storage unit 10. When the stop button 8 is pressed during recording, the communication control / processing means 1 first reads out the call voice recorded during the current call from the call voice storage means 6 and executes voice recognition and text conversion on the call voice. The converted text is stored in the call text storage means 9. Next, in order to associate the call information with the recorded call voice and the textized call text, the call voice storage means 6 stores a pointer indicating the storage location of the call voice, and the call text storage means 9 stores the call text. A pointer indicating the location and a call history ID and a pointer indicating the location where the call information is stored are obtained from the call history storage means 10 and recorded in the correspondence table in the association memory area of the association means 11. The display means 12 displays a call history display screen from the call history storage means 10, and if there is a call voice recorded corresponding to each call information with reference to the associating means 11, the call voice for each call information. If there is a call text stored corresponding to each call information with reference to the association means 11, an icon representing the call text is displayed for each call information. Here, “VOICE” will be described as an icon indicating call voice, and “TEXT” will be described as an icon indicating call text.

  On the other hand, when the icon “TEXT” representing the call text displayed on the call history display screen is selected, the operation means 14 detects it and refers to the call history storage means 10 to display the selected call history. A pointer to the call text corresponding to the call history ID and the selected call text is obtained and notified to the communication control / processing means 1. The communication control / processing unit 1 displays the corresponding call text in the call text storage unit 9 based on the pointer information.

FIG. 2 is a flowchart for explaining processing from the start of a call to the display of a call history display screen. 1 and 2, the communication control / processing unit 1 checks whether or not the automatic recording mode setting satisfies the conditions for the call in advance by setting the call (step ST1). If not satisfied, the normal call state is set (step ST13). If the condition is satisfied, the voice during the call is recorded and stored in the call voice storage means 6 (step ST4), and the recording state is set (step ST14). The recording state continues and recording continues as long as the recording state and the call state are continuing (step ST5) and the stop button 8 is not pressed (step ST6). When the stop button 8 is pressed during voice recording, the voice recording is stopped, voice recognition is performed to create a call text, and the call text is stored in the call text accumulating means 9 (step ST7) so that a normal call state is obtained. When the recording button 7 is pressed while the normal call state is continued (step ST3), the voice during the call is recorded and stored in the call voice storage means 6 to enter the recording state. At the end of the call state, if it is in the recording state at the same time, the voice recording is stopped, voice recognition is performed, a call text is created, and stored in the call text storage means 9 (step ST8). Next, the communication control / processing unit 1 notifies the call history storage unit 10 of the call information such as the telephone number of the call partner and the call start time, and stores it as a call history (step ST9).

Next, the associating means 11 includes pointer information indicating the storage location of the call voice from the call voice storage means 6, a pointer indicating the storage location of the call text and the call text from the call text storage means 9, and the call history storage means 10. The call history ID and a pointer indicating the location where the call information is stored are obtained and recorded in the correspondence table in the association memory area of the association means (step ST10).
When the call history display button 13 is pressed (step ST11), referring to the correspondence table and the call history storage means 10, call information having a call history ID that matches the call history ID entered in the correspondence table is displayed. If it exists in the call history storage means 10, it means the recorded call voice and call text, so the display means 12 displays the icon "VOICE" representing the recorded call voice and the icon "TEXT" representing the text call text. Is displayed and a call history display screen is displayed from the display means 12 (step ST12).
