- OpenSAT20 has completed for 2020 -

Welcome to the NIST 2020 Open Speech Analytic Technologies Evaluation (OpenSAT20)

OpenSAT20 supports the public safety communications domain with ASR, SAD and KWS.

Summary

OpenSAT20 is the second in the OpenSAT Series for speech analytic systems evaluations. OpenSAT provides an opportunity for participants to compare their system performance against a pool of systems performances for each task and is intended to encourage cross-learning among developers.

Click here for the OpenSAT20 Evaluation Plan (pdf). Updated July 1, 2020.

Tasks and Domains

System Tasks	Data Domains
Automatic Speech Recognition (ASR) Speech Activity Detection (SAD) Keyword Search (KWS)	Public safety communications (PSC)

Simulated Public Safety Communications (PSC)

The OpenSAT20 evaluation will include the ASR, SAD, and KWS tasks for simulated first responder public safety communications. Participants can participate with one, two, or all three tasks.

The simulated public safety communications dataset was created by LDC and funded by the Department of Homeland Security (DHS) to advance first responder assistant technologies in first responder noisy and stressed environments including its effects on speech. The public safety communications dataset includes simulated first responder communications with and without the Lombard effect in speech and moments in speech with expression of urgency. The audio also includes low-level and loud background sounds typical in first responder events.

The simulated first responder communications is intended to be a precursor in advancing assistive technologies for real-world operational communications. Real-world operational data is expected to be made available in future evaluations

Each participant, Site, and Team will have its own password. The creator(s) of the Site and Team creates those passwords respectively.

The NIST Agreement

Check the “I acknowledge that I have read and accepted the OpenSAT20 Terms and Conditions” box and then click the “Update the License Agreement” button.

The Data License Agreement

Site creator is required to agree to the LDC terms in order to access data for that site. Read the LDC license agreement and accept the terms by uploading the signed license agreement form. Participants cannot download data until LDC approves your uploaded signed LDC license agreement.

The Dashboard

The dashboard is the personalized page for each participant. To access the dashboard at any time, click the "Dashboard" at the top right of the screen. This is where you can make submissions and view results.

System Output Submission Instructions

Each submission must be associated with a Site, Team and Task.

Multiple systems may be created for each Task with a submission for each system.

Submit system output for validation checking or scoring following these steps:

1- Prepare for Submission

System output must be in the format described in the Evaluation Plan for the task that was performed (SAD, KWS, or ASR).
Have the .tgz or .zip file ready per Appendix IV in the OpenSAT20 Evaluation Plan and also shown below these steps.

2- Go to Dashboard. (Select "Dashboard" on the top right of the page.)

In "Submission Management", click the Task that represents the system output.
Click "Create new Submission" located at the upper right of the dashboard. A “Submission Name” page will display.

Select the Data Domain from the drop down
Enter a system identifier in “Name”.
Click “Submit”. A “Submissions” page will display.

On the “Submissions” page, click “Upload”. The “New Submission” page displays.

Click the "Choose File". Choose the .tgz or .zip file to upload.
Click "Submit".
A submission ID is automatically created for the submission.
The “Scoring” button on the “Submissions” page displays “submitted” until the scoring server completes scoring and then it changes to “Done”.
When “Done” is displayed, click “Scoring” button for a Scoring Run Report.
Click “View Submission” to see Submission information.

3- View Submission Results

To see a Scoring Run Report, click the “Scoring” button, after “submitted” changes to “Done” on the button.
To see information about the submission click the “View Submission” button.

Below is Appendix VI from the OpenSAT20 Evaluation Plan: Appendix IV- SAD, KWS, and ASR - System Output Submission Packaging

Each submission shall be an archive file named as "SysLabel".tgz or "SysLabel".zip.
Submit a separate .tgz or .zip file for each system output (e.g., a separate .tgz or .zip file for Primary, Contrastive1, and Contrastive2 systems).
"SysLabel" shall be an alphanumeric [a-zA-Z0-9] that is a performer-assigned identifier for their submission.
There should be no parent directory when the submission file is untarred. The tar command should be: > tar MySystemSubmissionFile.tgz or > tar MySystemSubmissionFile.zip respectively.

Prior to uploading the submission file to the NIST scoring server, performers will be asked for information about the submission. The scoring server will attach the following information to the submission filename to catorigize and uniquely identify the submission:

Field	Information	Method
TeamID	[Team]	obtained from login information
Task	{SAD \| ASR \| KWS}	select from drop-down menu
SubmissionType	{primary \| contrastive}	select from drop-down menu
SubmissionType	{primary \| contrastive}	select from drop-down menu
Training Condition	{unconstrained}	default - hard-coded
EvalPeriod	{2019}	default - hard-coded
DatasetName	{PSC \| VAST \| Babel}	select from drop-down menu
Date	{YYYYMMDD}	obtained from NIST scoring server at submission date
TimeStamp	{HHMMSS}	obtained from NIST scoring server at submission time

Below is an example of a resulting filename:

NIST_ASR_primary_uncontrained_2019_PSC_20190415_163026_ MySystemSubmissionFile.tgz

The NIST scoring server will perform a validation check on each system output submission for conforming to the submission format required for each task.

Submission of a system description conforming to the system description guidelines in Appendix V is required before receiving the system’s score and ranking results in the Evaluation phase.
