Abstract: A speech decoder includes a first portion comprising an adaptive codebook and a second portion comprising a fixed codebook. The decoder generates a speech excitation signal selectively based on output signals from said first and second portions when said decoder fails to receive reliably at least a portion of a current frame of compressed speech information. The decoder does this by classifying the speech signal to be generated as periodic or non-periodic and then generating an excitation signal based on this classification. If the speech signal is classified as periodic, the excitation signal is generated based on the output signal from the first portion and not on the output signal from the second portion. If the speech signal is classified as non-periodic, the excitation signal is generated based on the output signal from said second portion and not on the output signal from said first portion.

Title: Multimedia conferencing using parallel networks
Inventor: STERN EDITH HELEN
IPC: H04M3/00
Filed: 1997-12-05
Granted: 2002-05-07
Abstract: A conference server system, for internal use in the public switched telephone network (PSTN), links to public data communication networks (e.g. the Internet) for distributing computer displayable data between participants in voice telephone conferences. The server system includes a computer sub-system for storing data generated by the participants and distributing the data in coordination with voice presentations of respective participants. Data so stored and distributed includes computer-displayable data. Other data handled by the computer subsystem represents commands and functional requests issued by participants which pertain to the handling of computer-displayable data and voice parameters of the conference. Conference participants, having separate and concurrent access to both the PSTN and the data network, receive and view computer-displayable data prepared by one of the participants in coordination with the respective voice conference. The conference server system connects to voice conference managementresources of the PSTN in a manner enabling the server system to control voice parameters of a voice conference in response to data requests received from participants (e.g. requests from hearing-impaired participants for enhanced audio service), as well as enabling the conference management resources to control functions performed in respect to distribution of displayable data in response to spoken requests uttered by the participants, when the telephone system contains appropriate speech recognition equipment. Telephone system conferences utilizing the present conference server system have the advantage of being usable to support voice-only and/or data-only participants (participants respectively linked to only the voice or data distribution parts of a conference session), as well as to provide conference service between exactly two participants which may be more effective than comparable services that the same two participants would obtain using a direct dial-up telephone connection for voice and a public data network connection completely isolated from the voice conference management resources of the PSTN to exchange data.
