Abstract

This paper presents the design and results of the Rich Transcription Spring 2005 (RT-05S) Meeting Recognition Evaluation. This evaluation is the third in a series of community-wide evaluations of language technologies in the meeting domain. For 2005, four evaluation tasks were supported. These included a speech-to-text (STT) transcription task and three diarization tasks: Who Spoke When, Speech Activity Detection, and Source Localization. The latter two were first-time experimental proof-of-concept tasks and were treated as dry runs. For the STT task, the lowest word error rate for the multiple distant microphone condition was 30.0% which represented an impressive 33% relative reduction from the best result obtained in the last such evaluation -- the Rich Transcription Spring 2004 Meeting Recognition Evaluation. For the diarization Who Spoke When task, the lowest diarization error rate was 18.56% which represented a 19% relative reduction from that of RT-04S.
