摘要： A weapons system is disclosed that provides hot-start navigational information to the Global-Positioning-System receivers on missiles prior to flight. The system comprises a Global-Positioning-System receiver that uses a classified red cryptographic key to decode the P(Y) signal from one or more of the Global-Positioning-System constellation of satellites. Once the P(Y) signal is decoded, one or more characteristics (e.g., the PRN code synchronization, the Doppler shift, the modulation bit sequence, etc.) of the signal is derived. These characteristics of the signal—and some other information including a black cryptographic key that comprises the red cryptographic key—are then provided to the Global-Positioning-System receivers on missiles prior to flight. By giving the missiles this information, the missiles are able to acquire the P(Y) signals themselves more quickly than they otherwise could, which enables them to determine their position more quickly than they otherwise could.

摘要： A voice activated and operated Internet web browser where voiced utterances are digitized and the digitized representation is input to a speech recognition program is disclosed. The speech recognition program determines the most likely set of words from a stored vocabulary making up the utterances. The words are analyzed and searched against a database of topics or micro-domain areas. If a match occurs the words are analyzed by a subprogram associated with the specific topic area and key words are identified and other words discarded. The key words are input to a search engine or the equivalent. The search engine returns information associated with the topic. If no topic match is found a general search on the recognized words is performed. The recognized words are fed to a identification module where key words are extracted that are associated with names of people, organizations, locations, and companies; times; money amounts; percentages; dates; and not-a-name. The extraneous not-a-name words are discarded and the remaining key words are passed to a search engine. The search engine returns with web pages or other such information are found and displayed to the user. The user may re-run the identification module for marking hyperlinks for more particular information.

摘要： The invention provides a method of large vocabulary speech recognition that employs a single tree-structured phonetic hidden Markov model (HMM) at each frame of a time-synchronous process. A grammar probability is utilized upon recognition of each phoneme of a word, before recognition of the entire word is complete. Thus, grammar probabilities are exploited as early as possible during recognition of a word. At each frame of the recognition process, a grammar probability is determined for the transition from the most likely preceding grammar state to a set of words that share at least one common phoneme. The grammar probability is combined with accumulating phonetic evidence to provide a measure of the likelihood that a state in the HMM will lead to the word most likely to have been spoken. In a preferred embodiment, phonetic context information is exploited, even before the complete context of a phoneme is known. Instead of an exact triphone model, wherein the phonemes previous and subsequent to a phoneme are considered, a composite triphone model is used that exploits partial phonetic context information to provide a phonetic model that is more accurate than aphonetic model that ignores context. In another preferred embodiment, the single phonetic tree method is used as the forward pass of a forward/backward recognition process, wherein the backward pass employs a recognition process other than the single phonetic tree method.

摘要翻译： 本发明提供了一种在时间同步过程的每个帧处采用单个树结构语音隐马尔可夫模型（HMM）的大词汇语音识别方法。 在识别整个单词完成之前，在识别单词的每个音素时使用语法概率。 因此，在识别单词时尽可能早地利用语法概率。 在识别过程的每个帧处，确定从最可能的前一语法状态到共享至少一个公共音素的一组单词的转换的语法概率。 语法概率与积累的语音证据相结合，以提供HMM中的状态将导致最有可能发音的单词的可能性的量度。 在优选实施例中，甚至在已知音素的完整语境之前利用语音上下文信息。 考虑到音素之前和之后的音素被认为是一种精确的三音节模型，而是使用复合三音模型，它利用部分语音上下文信息来提供比忽略上下文的无声模型更准确的语音模型。 在另一个优选实施例中，使用单个语音树方法作为前向/后向识别过程的前向，其中后向通过采用除了单个语音树方法之外的识别过程。
