    摘要: The automatic completion of composite characters is supported by the generation of lists of candidate words or characters. Such lists may be generated by specifying letters or word shapes that are required to be included in candidate words or characters, independent of the order in which a specified letter or word shape is traditionally added to the completed word or character. In a subtractive mode, a user may exclude words or characters that include one or more letters or word shapes specified by the user.

    摘要翻译: 复合字符的自动完成由候选词或字符列表的生成支持。 这样的列表可以通过指定需要包括在候选词或字符中的字母或单词形状来生成,而不依赖于传统上将完整的字或字符添加到指定的字母或字形状的顺序。 在减法模式中,用户可以排除包括用户指定的一个或多个字母或字形的字或字。

    摘要: A method and apparatus for testing network performance are provided. In data provided by an application on a first host for transport or communication to an application associated with a second host according to a first data transport protocol is intercepted at the first host and wrapped or encapsulated in a test data packet formatted according to a second data transport protocol. The test data packet formatted according to the second data transport protocol includes, in addition to data comprising all or a portion of the original data packet, instrumentation information. The test data packet is then delivered to the second host, which unpacks the original data packet and the instrumentation information. A response packet containing instrumentation information may be sent from the second host to the first host to provide roundtrip performance metrics.

    摘要: The present invention is directed to voice communication devices in which an audio stream is divided into a sequence of individual packets, each of which is routed via pathways that can vary depending on the availability of network resources. All embodiments of the invention rely on an acoustic prioritization agent that assigns a priority value to the packets. The priority value is based on factors such as whether the packet contains voice activity and the degree of acoustic similarity between this packet and adjacent packets in the sequence. A confidence level, associated with the priority value, may also be assigned. In one embodiment, network congestion is reduced by deliberately failing to transmit packets that are judged to be acoustically similar to adjacent packets; the expectation is that, under these circumstances, traditional packet loss concealment algorithms in the receiving device will construct an acceptably accurate replica of the missing packet. In another embodiment, the receiving device can reduce the number of packets stored in its jitter buffer, and therefore the latency of the speech signal, by selectively deleting one or more packets within sustained silences or non-varying speech events. In both embodiments, the ability of the system to drop appropriate packets may be enhanced by taking into account the confidence levels associated with the priority assessments.
