Li Deng, Jian lai Zhou, Frank Torsten Bernd Seide, Asela J R Gunawardana, Hagai Attias, Alejandro Acero, Xuedong Huang: Method of speech recognition using time-dependent interpolation and hidden dynamic value classes. Microsoft Corporation, Theodore M Magee, Westman Champlin & Kelly P A, April 17, 2007: US07206741 (6 worldwide citation)

A speech signal is decoded by determining a production-related value for a current state based on an optimal production-related value at the end of a preceding state, the optimal production-related value being selected from a set of continuous values. The production-related value is used to determin ...
