Abstract:

The final report for the Speaker-Independent Connected Speech effort documents RCAs accomplishments in five general areas 1 A two hundred word database was recorded for a group of 46 speakers across eight samplings of dialect regions 2 A pitch synchronous acoustic parameter extraction algorithm was designed and implemented 3 A series of human perception experiments led to several conclusions which are pertinent to automatic speech recognition 4 A feature-based speaker-independent connected-digit recognizer was implemented 5 The parameter extraction and recognition algorithms were tested and evaluated under a variety of noise conditions.
