A system architecture for providing human intelligible information by processing a flow of input data; e.g., converting speech (source information) into printable data (target information) based on target-dependent probabilistic models; and for enabling efficient switching from one target field of information into another. To that end, the system is provided with a language modeling device including a data base loadable with an application-dependent corpus of words and/or symbols through a workstation; and a language modeling processor programmed to refresh, in practice, a tree-organized model, efficiently, with no blocking situations, and at a reasonable cost.
Method and apparatus for adaptively generating field of application dependent language models for use in intelligent systems
