摘要： Methods, devices, and software are provided for generating and sending data packets that contain redundant voice data over VoIP connections made under an unreliable network protocol. The redundant data is packaged either in redundant data packets, or in expanded original packets, to repeat data that originally belongs in other packets. Generation of the redundant voice data is either from the transmitting device or from a retransmitting device, such as a router in the network. Generation is triggered either when errors are detected, or simply when the network resources permit it, or both. The received voice data is processed by the second party to the connection, which is typically a telephone call. The redundant voice data that is actually received is discarded. The invention thus ensures that less voice data is lost than in the prior art over VoIP connections made under an unreliable network protocol.

摘要： Multiple audio streams are spatially separated with a context switching system to allow a listener to mentally focus on individual point sources of auditory information in the presence of other sound sources. The switching system simultaneously directs incoming sound sources to different spatial processors. Each spatial processor moves the received sound sources to different audibly perceived point sources. The outputs from the spatial processors are mixed into a stereo signal with left and right outputs and then output to the listener. Important sound sources are moved to a foreground point source for increased intelligibility while less important source sources are moved to a background point source.

摘要： Systems and methods are disclosed for packet voice conferencing. An encoding system accepts two sound field signals, representing the same sound field sampled at two spatially-separated points. The relative delay between the two sound field signals is detected over a given time interval. The sound field signals are combined and then encoded as a single audio signal, e.g., by a method suitable for monophonic VoIP. The encoded audio payload and the relative delay are placed in one or more packets and sent to a decoding device via the packet network.The decoding device uses the relative delay to drive a playout splitter—once the encoded audio payload has been decoded, the playout splitter creates multiple presentation channels by inserting the transmitted relative delay in the decoded signal for one (or more) of the presentation channels. The listener thus perceives a speaker's voice as originating from a location related to the speaker's physical position at the other end of the conference. An advantage of these embodiments is that a pseudo-stereo conference can be conducted with virtually the same bandwidth as a monophonic conference.
摘要翻译：公开了用于分组语音会议的系统和方法。编码系统接收两个声场信号，表示在两个空间分离点采样的相同声场。在给定的时间间隔内检测两个声场信号之间的相对延迟。声场信号被组合，然后被编码为单个音频信号，例如通过适合于单声道VoIP的方法。编码的音频有效载荷和相对延迟被放置在一个或多个分组中，并且经由分组网络被发送到解码装置。解码装置使用相对延迟来驱动播出分离器 - 一旦编码的音频有效载荷已被解码，播放分离器通过将一个（或更多个）演示频道的解码信号中插入传输的相对延迟来创建多个显示频道。因此，听众将演讲者的声音从与会议另一端的演讲人的身体位置相关的位置发出。这些实施例的优点是可以以与单声道会议几乎相同的带宽进行伪立体会议。

摘要： A system and method are disclosed for packet voice conferencing. The system and method divide a conferencing presentation sound field into sectors, and allocate one or more sectors to each conferencing endpoint. At some point between capture and playout, the voice data from each endpoint is mapped into its designated sector or sectors. Thereafter, when the voice data from a plurality of participants from multiple endpoints is combined, a listener can identify a unique apparent location within the presentation sound field for each participant. The system allows a conference participant to increase their comprehension when multiple participants speak simultaneously, as well as alleviate confusion as to who is speaking at any given time.

摘要： A PC-based server platform includes a first backplane bus used for transferring data and commands to various PC peripheral devices. A network router and a telephony endpoint card are coupled to the backplane bus and separately coupled through a second Time Division Multiplexed (TDM) bus. The router includes interfaces to various packet switched networks such as a Wide Area Network (WAN) and a Local Area Network (LAN). The TDM bus is used to route telephony data between the different Internet Protocol (IP)-based networks and the telephony card independently of the host system. The PC host processor also uses the router as a standard LAN interface for transferring data packets. A DSP voice processing card is coupled between the backplane bus and the TDM bus to compress and decompress the telephony data transferred on the TDM bus.
