摘要： System and method to improve intelligibility of coded speech, the method including: receiving an encoded speech signal from a network; extracting an encoded media data stream and one or more control data packets from the encoded speech signal; decoding the encoded media data stream to produce a decoded speech signal; boosting an upper spectral portion of the decoded speech signal to produce a boosted speech signal; and outputting the boosted speech signal. In another embodiment, the method may include: receiving an uncoded speech signal; processing the uncoded speech signal, wherein the processing comprises generating an unencoded data stream from the uncoded speech signal; boosting an upper spectral portion of the unencoded data stream to produce a boosted speech signal; encoding the boosted speech signal to produce an encoded speech signal; and outputting the boosted speech signal.

摘要： There is no common clock between two system over an asynchronous interface, such as an asynchronous network or bus. The rate of data transmission of constant bit rate data from one system can be considered constant when averaged over time. A receive system can synchronize its system clock by using timing information derived by counting received packets over a predetermined period of time.
摘要翻译：通过异步接口（例如异步网络或总线），两个系统之间没有通用时钟。当一段时间内平均时，来自一个系统的恒定比特率数据的数据传输速率可以被认为是恒定的。接收系统可以通过使用通过在预定时间段内对接收到的分组进行计数而导出的定时信息来同步其系统时钟。

摘要： A key telephone system (KTS) or a telephone private branch exchange (PBX) card is integrated into a personal computer to provide telephone system features. The telephone card includes a call controller, a switching network and an interface bus controller for coupling data signals between the PCI bus and an internal bus of the call controller whereby the telephone card is able to communicate with resources of the PC such as a LAN and a hard disk bulk memory for executing telecommunications functions. In this arrangement the PCI bus must carry both asynchronous data processing and control signals as well as reformatted synchronous signals. The addition of a synchronous bus for transporting synchronous signals is used to couple these signals between the switching network, a telephony features controller and the hard disk bulk memory. The use of the synchronous bus provides for improved telephone traffic capacity and PC functionality.
