[Operation of First Embodiment]
Next, the operation of the telephone device according to the first embodiment of the present invention will be described with reference to FIG. FIG. 2 is a sequence diagram showing an incoming call operation of the telephone device according to the first embodiment of the present invention. Here, a case will be described in which a call path is established and a call is started after answering an incoming call from the partner telephone device 4.

The counterpart telephone device 4 transmits a connection request message to the data communication network 3 in order to call the destination telephone device 1 designated by the outgoing operation in response to the outgoing operation by the originating user (step 100). (Step 101).
This connection request message is transferred to the telephone device 1 via the data communication network 3 and the communication line 2.

When the communication I / F unit 11 receives the connection request message from the partner telephone device 4, the control unit 16 of the telephone device 1 controls the voice processing unit 12 and the display unit 14 with the communication control unit 16 </ b> A to receive the message. An incoming call display for informing the side user that the incoming call has been detected is started (step 102). Further, the communication control means 16A transmits a calling message from the communication I / F unit 11 to the destination telephone device 4 (step 103).
The partner telephone device 4 receives the ringing message from the telephone device 1 via the data communication network 3 and sends a ringing tone for notifying the calling user of the calling (step 104).

  Thereafter, when the control unit 16 of the telephone device 1 detects a response operation such as off-hook by the callee user using the operation input unit 13 (step 110), the communication processing unit 16A causes the voice processing unit 12 and the display unit 14 to be switched. The incoming call display is stopped by control (step 111), and a response message is transmitted from the communication I / F unit 11 to the destination telephone device 4 (step 112). At this time, media control information such as an encoding rule that can be used for voice data exchanged with the other party telephone device 4 is notified by the response message.

  After the response operation, the communication control means 16A switches and outputs the voice input from the transmitter 12A and converted into voice data by the voice processing unit 12 only to the voice recording means 16B (step 113). The means 16B starts processing to record the sound as recorded sound data 15A in the storage unit 15 (step 114). For this reason, the voice data from the voice processing unit 12 is not directly output to the communication path with the other party telephone apparatus 4 established thereafter.

  The partner telephone device 4 receives the response message from the telephone device 1 via the data communication network 3, stops transmission during the call (step 115), and then transmits a response confirmation message addressed to the telephone device 1 (step 115). 116). At this time, a coding rule used for voice data exchanged with the telephone device 1 is selected from the coding rules notified from the telephone device 1 by the partner telephone device 4, and the voice processing unit of the partner phone device 4 is selected. (Not shown) and is notified to the telephone device 1 by a response confirmation message.

When the control unit 16 of the telephone device 1 receives the response confirmation message from the partner telephone device 4 via the communication I / F unit 11, the communication control unit 16A determines the encoding rule notified by the response confirmation message. Set in the voice processing unit 12.
As a result, a call path is established between the other telephone apparatus 4 and the telephone apparatus 1 via the data communication network 3, and voice data for a call can be transmitted and received (step 117).

After the communication path is established, the communication control means 16A starts the process of reproducing the recorded voice data 15A in the storage unit 15 by fast-forwarding and sending it to the communication path by the voice reproduction means 16C (step 120). As a result, after the answering operation, the transmission voice input by the called user from the transmitter 12A and sequentially recorded in the storage unit 15 is sequentially transmitted to the communication path by fast-forwarding after the communication path is established. Is output.
Thereafter, when transmission of the recorded voice data 15A is completed (step 121: YES), the communication control means 16A stops recording by the voice recording means 16B (step 122) and the voice input from the transmitter 12A. Is switched from the voice recording means 16B to the communication path (step 123), and a series of incoming operations are terminated.

FIG. 3 is a timing chart showing the operation of the telephone device according to the first embodiment of the present invention.
When a response operation is performed at time T1 (step 110 in FIG. 2), the recording process by the voice recording unit 16B is started accordingly. At this time, the user's voice input from the transmitter 12A is switched and output only to the voice recording means 16B. Thereby, the voices V1 and V2 input after the response operation are sequentially recorded in the storage unit 15 as the recorded voice data 15A.

Thereafter, when a speech path is established at time T2 (step 116 in FIG. 2), reproduction processing by the audio reproduction means 16C is started. As a result, the voices V1 and V2 recorded as the recorded voice data 15A in the storage unit 15 are reproduced by fast-forwarding and sequentially sent to the speech path.
In this case, since the recording process in the voice recording unit 16B is performed in parallel, the user's voice V3 input after time T2 is once recorded in the storage unit 15 as the recorded voice data 15A. It is reproduced by fast-forwarding and sequentially sent out to the communication path.

  Thereafter, at time T3, when the voice V3 is played and the playback process by the voice playback unit 16C is finished, the recording process by the voice recording unit 16B is stopped and the user's input from the transmitter 12A is stopped. Audio is switched and output to the communication path. As a result, the voice V4 input from the transmitter 12A after time T3 is not recorded, but directly output to the call path, and the normal voice call is resumed.

  As described above, in this embodiment, the communication control means 16A of the telephone device 1 uses the voice input from the transmitter 12A by the voice recording means 16B as the recorded voice after the response operation to the incoming call from the other telephone device. The process of recording is started, and in response to the establishment of the communication path with the other party's telephone device thereafter, the process of reproducing the recorded voice at high speed by the voice reproduction means 16C and sending it to the communication path is started, and the recording voice data is transmitted. In response to the end, the recording by the voice recording means 16B is stopped and the voice input from the transmitter 12A is sent to the speech path.

For this reason, even after the response operation, even if the user starts speaking before the call path is established, the user's voice is sequentially recorded in the storage unit, and after the call path is established, the recorded voice is fast-forwarded to the call path. Sequentially sent and output to the other party telephone device.
Therefore, even when processing from the incoming call response operation to the establishment of the call path takes time, the influence on the call due to the interruption of the talk can be suppressed, and a smooth call can be realized.
