Abstract

In a telephone conference system including IP telephone terminals for transmitting and receiving packeted and encoded voice information that are connected to each other through an IP network; a storage server for being connected through the IP network and storing the encoded voice information is equipped, a marker assigning unit for generating marker information assigned to the encoded voice information at arbitrary timing is included in the IP telephone terminal; network address information, time information, and the marker information are associated with the encoded voice information to store them in the storage server when the marker information is generated. In addition, an agenda selecting unit is included in the IP telephone terminal, and only the encoded voice information assigned with the marker information corresponding to an agenda selected by the agenda selecting unit is used from the encoded voice information stored in the storage server to reproduce voice.

Claims

1. An IP telephone terminal that transmits and receives packeted and encoded voice information, comprising:

a marker assigning unit that assigns marker information to the encoded voice information,

wherein the IP telephone terminals are connected to a storage server over an IP network, the storage server storing the encoded voice information and the marker information assigned by the marker assigning unit by associating them.

2. The IP telephone terminal according to claim 1, further comprising:

an agenda selecting unit; and

a voice reproducing unit that reproduces voice using the encoded voice information stored in association with the marker information corresponding to the agenda selected by the agenda selecting unit.

3. The IP telephone terminal according to claim 1, further comprising a text information display unit that displays text information converted from the encoded voice information stored in the storage server.

4. The IP telephone terminal according to claim 1, wherein the storage server stores network address information as well as the marker information in association with the encoded voice information, and

wherein the IP telephone terminal further comprises:

a network address assigning unit; and

a voice reproducing unit that reproduces voice using the encoded voice information associated with the network address information agreeing with the network address assigned by the network address assigning unit.

5. The IP telephone terminal according to claim 1,

wherein the storage server stores time information as well as the marker information in association with the encoded voice information, and

wherein the IP telephone terminal further comprises:

a timing generating unit; and

a voice reproducing unit that reproduces voice using the encoded voice information associated with the time information agreeing with the time appointed by the timing generating unit.

6. The IP telephone terminal according to claim 1,

wherein the storage server stores network address information and time information as well as the marker information in association with the encoded voice information,

wherein the IP telephone terminal further comprises:

a speech congestion determining unit that detects congestion of plural speeches; and

a voice reproducing unit that makes timing of the respective speeches different using the network address information and the timing information and reproduces voice using the encoded voice information to be reproduced, when the speech congestion determining unit detects the congestion of the speeches with respect to the encoded voice information to be reproduced.

7. The IP telephone terminal according to any one of claims 2, 4, 5, and 6, further comprising a gain control unit that controls the volume of reproduction voice for every transmission source of the encoded voice information corresponding to voice, when the voice reproducing unit reproduces the voice.

8. The IP telephone terminal according to any one of claims 2, 4, 5, and 6, further comprising a voice modulating unit that modulates reproduction voice for every transmission source of the encoded voice information corresponding to voice, when the voice reproducing unit reproduces the voice.

9. The telephone conference system comprising the IP telephone terminals according to claim 1 and a storage server.
