Intel virtualization technology

A virtualized system includes a new layer of software, the virtual machine monitor. The VMMs principal role is to arbitrate accesses to the underlying physical host platforms resources so that multiple operating systems (which are guests of the VMM) can share them. The VMM presents to each guest OS a set of virtual platform interfaces that constitute a virtual machine (VM). Once confined to specialized, proprietary, high-end server and mainframe systems, virtualization is now becoming more broadly available and is supported in off-the-shelf systems based on Intel architecture (IA) hardware. This development is due in part to the steady performance improvements of IA-based systems, which mitigates traditional virtualization performance overheads. Intel virtualization technology provides hardware support for processor virtualization, enabling simplifications of virtual machine monitor software. Resulting VMMs can support a wider range of legacy and future operating systems while maintaining high performance.

Selecting one of multiple speech recognizers in a system based on performance predections resulting from experience

A method for selecting a speech recognizer from a number of speech recognizers in a speech recognition system. The speech recognition system receives an audio stream from an application and derives enabling information. The speech recognition system then enables at least some of the speech recognizers and receives their results. It derives selection information and uses it to select the best speech recognizer and its results and returns those results back to the application.
