摘要： An Active User Registry system includes a database which is integrated with the POTS network and a packet network to exploit the outstanding strengths of both of its constituents. The Active User Registry database is a dynamic data structure of all the ways in which one or more users can be reached via some type of communication network. A key feature of the Active User Registry is the ability to broker between a subscriber's request for communications contact information corresponding to a user and the user's preferences of being reached by various communications alternatives.

摘要： Speaker independent recognition of small vocabularies, spoken over the long distance telephone network, is achieved using two types of models, one type for defined vocabulary words (e.g., collect, calling-card, person, third-number and operator), and one type for extraneous input which ranges from non-speech sounds to groups of non-vocabulary words (e.g. `I want to make a collect call please`). For this type of key word spotting, modifications are made to a connected word speech recognition algorithm based on state-transitional (hidden Markov) models which allow it to recognize words from a pre-defined vocabulary list spoken in an unconstrained fashion. Statistical models of both the actual vocabulary words and the extraneous speech and background noises are created. A syntax-driven connected word recognition system is then used to find the best sequence of extraneous input and vocabulary word models for matching the actual input speech.
摘要翻译：使用两种类型的模型来实现对长途电话网络上的小词汇的独立识别，一种用于定义的词汇单词（例如，收集，呼叫卡，人，第三号码和运营商）的模型，以及一种类型对于从非语音声音到非词汇单词组（例如“我想要收集电话”）的无关输入。对于这种类型的关键词发现，对基于状态转换（隐马尔科夫）模型的连接词语音识别算法进行修改，这允许其识别来自以无限制方式说明的预定义词汇列表中的单词。创建实际词汇单词和无关语音和背景噪声的统计模型。然后使用语法驱动的连接词识别系统来找到用于匹配实际输入语音的外来输入和词汇词模型的最佳序列。

摘要： Recorded telephone messages may be automatically handled as specified by the called party by means of a background speech recognition server for a telephone network, a private branch exchange, or a personal computer telephone manager. The called party initializes the method by storing multiple action records in a computer, each containing a key word and an action description. Incoming telephone messages can then be automatically processed by subjecting the audio record of each message to a speech recognition program to produce a text record. The computer then compares the text record with the key words in the action records. When a match is found, the action specified in the action record bearing the matching key words, is performed. In this manner, recorded telephone messages may be automatically handled and prioritized as specified by the called party.

摘要： A general purpose interpolator-decimator circuit for increasing or decreasing the sampling rate of a digital signal by a factor L/M, where L and M are integers, is disclosed. The circuit includes means for determining each output sample by multiplying a sequence of previous input samples by a set of coefficients and accumulating the resulting products. L sets of coefficients, in which each coefficient is a function of the factors L and M, are stored in a specific sequence which permits sequential addressing of both the coefficients and input signal samples. A multistage decimator cascaded with a multistage interpolator to effect a narrow-band FIR filter is also disclosed.
