    • A computer implemented method, system and computer program product for evaluating pronunciation. Known phonemes are stored in a computer memory. A spoken utterance corresponding to a target utterance, comprised of a sequence of target phonemes, is received and stored in a computer memory. The spoken utterance is segmented into a sequence of spoken phonemes, each corresponding to a target phoneme. For each spoken phoneme, a relative posterior probability is calculated that the spoken phoneme is the corresponding target phoneme. If the calculated probability is greater than a first threshold, an indication that the target phoneme was pronounced correctly is output; if less than a first threshold, an indication that the target phoneme was pronounced incorrectly is output. If the probability is less than a first threshold and greater than a second threshold, an indication that pronunciation of the target phoneme was acceptable is output.
    • 一种用于评估发音的计算机实现方法,系统和计算机程序产品。 已知的音素被存储在计算机存储器中。 由目标音素序列组成的与目标语音对应的语音话语被接收并存储在计算机存储器中。 讲话的话语被分割成一系列的语音音素,每个对应的是一个目标音素。 对于每个口语音素,计算相对后验概率,即口语音素是相应的目标音素。 如果计算出的概率大于第一阈值,则输出目标音素被正确发音的指示; 如果小于第一阈值,则输出目标音素发音不正确的指示。 如果概率小于第一阈值且大于第二阈值,则输出目标音素的发音是可接受的指示。

    • A protocol engine is for use in each node of a computer system having a plurality of nodes. Each node includes an interface to a local memory subsystem that stores memory lines of information, a directory, and a memory cache. The directory includes an entry associated with a memory line of information stored in the local memory subsystem. The directory entry includes an identification field for identifying sharer nodes that potentially cache the memory line of information. The identification field has a plurality of bits at associated positions within the identification field. Each respective bit of the identification field is associated with one or more nodes. The protocol engine furthermore sets each bit in the identification field for which the memory line is cached in at least one of the associated nodes. In response to a request for exclusive ownership of a memory line, the protocol engine sends an initial invalidation request to no more than a first predefined number of the nodes associated with set bits in the identification field of the directory entry associated with the memory line.
    • 协议引擎用于具有多个节点的计算机系统的每个节点。 每个节点包括存储信息存储线,目录和存储器高速缓存的本地存储器子系统的接口。 目录包括与存储在本地存储器子系统中的信息的存储器线相关联的条目。 目录条目包括用于识别可能缓存信息的存储器线的共享者节点的标识字段。 识别字段在识别字段内的关联位置具有多个位。 识别字段的每个相应位与一个或多个节点相关联。 协议引擎还将存储线被高速缓存的标识字段中的每一位设置在相关联的节点中的至少一个中。 响应于对存储器线路的独占所有权的请求,协议引擎将初始无效请求发送到与存储器线相关联的目录条目的标识字段中与设置位相关联的不超过第一预定数量的节点。
