Washington, District of Columbia-based Entropic Research Laboratory Inc says it has HTK, the Hidden Aprkov Model Toolkit, providing the software tools needed to build Hidden Aprkov pattern classification and continuous speech recognition systems. The company claims the product, originally developed by the Cambridge University Engineering Department Speech Group and available through an exclusive alliance with Cambridge University Technology Transfer Co, marks the first time these capabilities have been available in a single commercial product. Users do not need to write computer programs, it says. The software is currently offered on Sun Microsystems Inc, Hewlett-Packard Co, Digital Equipment Corp and Silicon Graphics Inc workstations.
