Abstract
We describe the ICSI-SRI-UW team’s entry in the Spring 2004 NIST Meeting Recognition Evaluation. The system was derived from SRI’s 5xRT Conversational Telephone Speech (CTS) recognizer by adapting CTS acoustic and language models to the Meeting domain, adding noise reduction and delay-sum array processing for far-field recognition, and postprocessing for cross-talk suppression. A modified MAP adaptation procedure was developed to make best use of discriminatively trained (MMIE) prior models.[…]
