Maternal and Breastmilk Viral Load: Impacts of Adherence on Peripartum HIV Infections Averted—The Breastfeeding, Antiretrovirals, and Nutrition Study

Antiretroviral interventions are used to reduce HIV viral replication and prevent mother-to-child transmission. Viral suppression relies on adherence to antiretrovirals

The Rich Transcription 2006 Spring Meeting Recognition Evaluation

Abstract. We present the design and results of the Spring 2006 (RT-06S) Rich Transcription Meeting Recognition Evaluation; the fourth in a series of community-wide evaluations of language technologies in the meeting domain. For 2006, we supported three evaluation tasks in two meeting sub-domains: the Speech-To-Text (STT) transcription task, and the “Who Spoke When ” and “Speech Activity Detection ” diarization tasks. The meetings were from the Conference Meeting, and Lecture Meeting sub-domains. The lowest STT word error rate, with up to four simultaneous speakers, in the multiple distant micro-phone condition was 46.3 % for the conference sub-domain, and 53.4 % for the lecture sub-domain. For the “Who Spoke When ” task, the lowest diarization er-ror rates for all speech were 35.8 % and 24.0 % for the conference and lecture sub-domains respectively. For the “Speech Activity Detection ” task, the lowest diarization error rates were 4.3 % and 8.0 % for the conference and lecture sub-domains respectively. 1

1996 Preliminary Broadcast News Benchmark Tests

This paper documents use of Broadcast News test materials in DARPA-sponsored Automatic Speech Recognition (ASR) Benchmark Tests conducted late in 1996. In this year's tests, the source materials were broadened to incorporate both television and radio news broadcasts. A form of "partitioned evaluation" (PE) testing was implemented for the first time. At three sites, an additional testing protocol -- similar to that used in last year's "Dry Run" tests [1] -- was used, now termed an "Unpartitioned Evaluation" (UE). Participants in these tests included nine groups at eight sites: BBN Systems and Technologies, Cambridge University (two groups), Carnegie Mellon University, IBM, LIMSI, New York University, Rutgers University, and SRI International. Evaluation Test Set Word Error Rates are reported for the complete evaluation test set, drawn from 4 news broadcasts (2 radio and 2 TV), and for each "Focus Condition", corresponding to seven pre-defined subsets of similarly annotated data.
