    摘要： Aspects of this disclosure provide techniques for generating a viseme and corresponding intensity pair. In some embodiments, the method includes generating, by a server, a viseme and corresponding intensity pair based at least on one of a clean vocal track or corresponding transcription. The method may include generating, by the server, a compressed audio file based at least on one of the viseme, the corresponding intensity, music, or visual offset. The method may further include generating, by the server or a client end application, a buffer of raw pulse-code modulated (PCM) data based on decoding at least a part of the compressed audio file, where the viseme is scheduled to align with a corresponding phoneme.

    摘要： A non-transitory processor-readable medium stores code representing instructions to be executed by a processor. The code causes the processor to receive a request from a user of a client device to initiate a speech recognition engine for a web page displayed at the client device. In response to the request, the code causes the processor to (1) download, from a server associated with a first party, the speech recognition engine into the client device; and then (2) analyze, using the speech recognition engine, content of the web page including text in an identified language to produce analyzed content based on the identified language, where the content of the web page is received from a server associated with a second party. The code further causes the processor to send a signal to cause the client device to present the analyzed content to the user at the client device.

    摘要： The content of an instructor-student interaction set in an automated teaching system is represented in a graph-based format. In a graph-based representation, not only can variations branch away from each other at a node (branching point), as in the tree-based representation, but they can also merge back together. Not only does this make the -structure more compact, but it increases the number of variations that can be represented in the content while simultaneously eliminating the need to individually author each variation.

    摘要翻译： 自动化教学系统中的教师 - 学生交互设置的内容以基于图表的格式表示。 在基于图形的表示中，不仅可以使变量在一个节点（分支点）上彼此分支，如在基于树的表示中，而且它们也可以合并在一起。 这不仅使得结构更紧凑，而且增加了可以在内容中表示的变化的数量，同时消除了对每个变体的单独编写的需要。

    摘要： A non-transitory processor-readable medium storing code representing instructions to be executed by a processor includes code to cause the processor to receive acoustic data representing an utterance spoken by a language learner in a non-native language in response to prompting the language learner to recite a word in the non-native language and receive a pronunciation lexicon of the word in the non-native language. The pronunciation lexicon includes at least one alternative pronunciation of the word based on a pronunciation lexicon of a native language of the language learner. The code causes the processor to generate an acoustic model of the at least one alternative pronunciation in the non-native language and identify a mispronunciation of the word in the utterance based on a comparison of the acoustic data with the acoustic model. The code causes the processor to send feedback related to the mispronunciation of the word to the language learner.
