  • Instantaneous context switching for speech recognition systems
    Patent number: 5513298
    Abstract: An instantaneous context switching speech recognition system is disclosed which enables a speech recognition application to be changed without loading new pattern matching data into the system. Selectable pointer maps are included in the memory of the system which selectively change the relationship between words and phonemes between a first application context and the pattern matching logic to a second application context and the pattern matching logic.

  • Telephony channel simulator for speech recognition application
    Patent number: 5475792
    Abstract: A telephony channel simulation process is disclosed for training a speech recognizer to respond to speech obtained from telephone systems. An input speech data set is provided to a speech recognition training processor, whose bandwidth is higher than a telephone bandwidth. The process performs a series of alterations to the input speech data set to obtain a modified speech data set. The modified speech data set enables the speech recognition processor to perform speech recognition on voice signals from a telephone system.
