摘要： A phonetic vocabulary for a speech recognition system is adapted to a particular speaker's pronunciation. A speaker can be attributed specific pronunciation styles, which can be identified from specific pronunciation examples. Consequently, a phonetic vocabulary can be reduced in size, which can improve recognition accuracy and recognition speed.
摘要翻译：用于语音识别系统的语音词汇适用于特定说话者的发音。扬声器可以归因于特定的发音风格，可以从具体的发音示例中识别。因此，可以减小语音词汇量，从而提高识别精度和识别速度。

摘要： Bootstrapping of a system from one language to another often works well when the two languages share the similar acoustic space. However, when the new language has sounds that do not occur in the language from which the bootstrapping is to be done, bootstrapping does not produce good initial models and the new language data is not properly aligned to these models. The present invention provides techniques to generate context dependent labeling of the new language data using the recognition system of another language. Then, this labeled data is used to generate models for the new language phones.
摘要翻译：当两种语言共享相似的声学空间时，将系统从一种语言引导到另一种语言通常会很好。然而，当新语言的语音不会出现在引导引导的语言中时，引导不会产生良好的初始模型，并且新的语言数据未正确对齐这些模型。本发明提供了使用另一种语言的识别系统来生成新语言数据的上下文相关标签的技术。然后，这个标记的数据用于生成新语言手机的模型。

摘要： A method, a computer system and a computer program product for generating baseforms or phonetic spellings from input text are disclosed. The baseforms are initially generated using rules defined for a particular language. Then, phones are identified in the language that are exceptions to the defined rules and an action is associated with each identified phone. A statistical technique is applied to determine whether the identified phones can be modified. Finally, baseforms containing the identified phones that can be modified, are corrected according to the associated actions. Preferably, the statistical technique is only applied to baseforms containing phones that are exceptions to the defined rules. The defined rules can comprise spelling-to-sound rules for a particular phonetic language that incorporate all possible alternative pronunciations of each baseform.

摘要： A computer implemented method in a language independent system generates audio-driven facial animation given the speech recognition system for just one language. The method is based on the recognition that once alignment is generated, the mapping and the animation hardly have any language dependency in them. Translingual visual speech synthesis can be achieved if the first step of alignment generation can be made speech independent. Given a speech recognition system for a base language, the method synthesizes video with speech of any novel language as the input.

摘要： The present invention provides a hybrid call handling method and system. The method comprises navigating a plurality of received calls from a plurality of callers. The method further comprises monitoring a call health status for each of the plurality of the calls being navigated for entire call duration and notifying a bad call health status of the monitored call to a human agent for employing at least one rectification action. The call health status is determined by monitoring and measuring one or more call parameters. The invention provides for a system for call handling and navigation by an automated system with a human agent assisting the automated system for rectification of calls with bad call health status. Once the call with a bad health is transferred to the human agent, he assists the automated system either by directly communicating with the caller or by communicating using a machine interface.

摘要： A language model is constructed for mixed language expressions that have words from more than one natural language. Word equivalence probabilities for pairs of words among the languages are generated and stored. Word equivalence probabilities are used as required to generate a monolingual word history. The monolingual history is used by a monolingual language model to generate a next-word hypothesis. The word equivalence probabilities are also used to compute the next word probabilities in the foreign language.
