Want to teach or learn about speech processing? Need resources? The Speech Recognition Virtual Kitchen [speechkitchen.org] might be helpful:
The Speech Recognition Virtual Kitchen aims to extend the model of lab-internal knowledge transfer to community-wide dissemination through the use of virtual machines, with the primary goal of cultivating student interest in speech recognition via immediate, straightforward access to the tools and techniques used by advanced researchers. Speech recognition draws from many disciplines (e.g., phonetics, linguistics, computer science, electrical engineering, physics), each with myriad idiosyncratic computational methods and practices, making it difficult to establish an initial educational code base (or improve upon the state of the art). The kitchen environment addresses this difficulty through the use of virtual machines that provide a consistent, end-to-end environment for experimentation, without the need to install other software or data, and cope with their incompatibilities and peculiarities.
The Kitchen is flexible and can be used in many ways:
