Patent number: 8774388Abstract: A telephone terminal executes voice communication with a partner telephone terminal by using a selected codec program to code and decode voice signals. Both telephone terminals have facilities for storing codec programs and transferring codec programs over a communication network. During a voice call, one of the two telephone terminals may transfer a codec program to the other telephone terminal, and the call may then proceed by use of the transferred codec program. This enables voice communication to take place with the best codec program that either telephone terminal can provide, even if the two telephone terminals are associated with different communication systems.Type: GrantFiled: August 30, 2007Date of Patent: July 8, 2014Assignee: Oki Electric Industry Co., Ltd.Inventors: Shinji Usuba, Tatsuya Satoh, Kouki Yamaguchi

Patent number: 8484039Abstract: A voice mixing apparatus decodes input encoded narrowband voice data and encoded voice data for narrowband region of input encoded wideband voice data, and detects a speaker in accordance with the decoded voice signals of the entire narrowband. When encoded voice data from a speaker is included in the narrowband, a signal in a region outside the narrowband of the expanded data is encoded. When the data is included in the wideband, encoded voice data of the region outside the narrowband is extracted for output. When the destination terminal is compatible with the encoded narrowband voice data, the narrowband voice signal mixed is encoded and output. When the destination terminal is compatible with wideband, the narrowband voice signal mixed is encoded for the narrowband region, and the voice data of the speaker is used as the encoded voice data for the region outside the narrowband.Type: GrantFiled: February 3, 2010Date of Patent: July 9, 2013Assignee: Oki Electric Industry Co., Ltd.Inventors: Hiromi Aoyagi, Shinji Usuba
