The SAPPHIRE system is a powerful, extensible, object oriented toolkit allowing researchers to rapidly build and configure customized speech analysis tools. Implemented in Tcl/Tk and C, the current version of SAPPHIRE provides a wide range of functionality, including the ability to configure and run the SUMMIT speech recognition system. We use SAPPHIRE widely in almost all aspects of our speech analysis and recognition research.
