The NIST Open Speech-Activity-Detection evaluation (OpenSAD) was intended to provide Speech-Activity-Detection (SAD) system developers with an independent evaluation of performance on a variety of audio data. The purpose of a SAD system is to find regions of speech in an audio file. The purpose of the evaluation was to advance SAD technology and broaden the research community.

## Documentation

                  - Evaluation Plan  (Version 10.0, May-12-2016)
                  - LDC Data-license agreement    (Note:  The evaluation is over, and we are no longer accepting license agreements.)  

## Changes in version 10 of the Evaluation Plan

                  - Updated to reflect what actually happened in the OpenSAD evaluation

## Scoring software

                  - OpenSAD scoring software tarball  -- includes mock example data  

## Schedule (dates are all in 2015)

                  - September 3:  Publish registration form, mock data, and beta-version scoring code
                  - September 7:  Release data-license agreements, from LDC
                  - Sept. 21: Release Training and DevTest datasets and release beta-version scoring code
                  - Oct. 1: Participant registration deadline
                  - Nov. 2-13: Evaluation period (two weeks to accommodate multi-site teams)
                  - Nov. 26: Release preliminary results (automated, non-refereed)
                  - Dec. 18: One-day OpenSAD workshop at NIST (Gaithersburg, MD)
                  - End of December:  Release official results
