摘要： A method and apparatus for interactive language instruction is provided that displays text files for processing, provide key features and functions for interactive learning, displays facial animation, and provides a workspace for language building functions. The system includes a stored set of language rules as part of the text-to-speech sub-system, as well as another stored set of rules as applied to the process of learning a language. The method implemented by the system includes digitally converting text to audible speech, providing the audible speech to a user or student (with the aid of an animated image in selected circumstances), prompting the student to replicate the audible speech, comparing the student's replication with the audible speech provided by the system, and providing feedback and reinforcement to the student by, for example, selectively recording or playing back the audible speech and the student's replication.

摘要： A speaker verification method and apparatus which advantageously minimizes the constraints on the customer and simplifies the system architecture by using a speaker dependent, rather than a speaker independent, background model, thereby obtaining many of the advantages of using a background model in a speaker verification process without many of the disadvantages thereof. In particular, no training data (e.g. speech) from anyone other than the customer is required, no speaker independent models need to be produced, no a priori knowledge of acoustic rules are required, and, no multi-lingual phone models, dictionaries, or letter-to-sound rules are needed. Nonetheless, in accordance with an illustrative embodiment of the present invention, the customer is free to select any password phrase in any language. Specifically, and in accordance with an illustrative embodiment of the present invention, the background model comprises a hidden Markov model having a cruder acoustic resolution than the customer model, which may, for example, be achieved by providing a background model containing fewer states than the customer model.
摘要翻译：扬声器验证方法和装置，其有利地最小化对客户的约束并且通过使用说话者依赖而不是独立于扬声器的背景模型来简化系统架构，从而获得在说话者验证过程中使用背景模型的许多优点没有许多缺点。特别是，不需要除客户以外的任何人员的培训数据（例如语音），不需要制作无须讲话的独立模型，不需要对声学规则的先验知识，也不需要多语言手机模型，词典或需要符合条件的规则。然而，根据本发明的说明性实施例，客户可以随意选择任何语言的任何密码短语。具体地，根据本发明的说明性实施例，背景模型包括具有比客户模型更为重要的声音分辨率的隐马尔可夫模型，其可以例如通过提供包含比该模型更少的状态的背景模型来实现客户型号。
