Contribute software

To contribute new software, please

• create an account and login
• go to the wiki page above corresponding to your application; if it does not exist yet, you may create it
• click on the "Edit" link at the top of the page and add a new section for your software (software is ordered by year of the latest version)
• click on the "Save page" link at the bottom of the page to save your modifications

Please make sure to provide the following information:

• name of the software and year of the latest version
• authors, institution, contact information
• link to the software, ideally including a short demo, and to the external libraries needed
• short description (functionalities, inputs and outputs, programming language, operating system, license, etc) and link to a paper/report describing the software, if any
• whether running on well-known baselines (Aurora-2, Aurora-4, Switchboard, CHiME, etc) is included or requires wrapping by the user

In order to save storage space, please do not upload the software on this wiki, but link it as much as possible from a public repository (e.g., bitbucket, github, sourceforge) or from a stable URL on the website of your institution. If this is not possible, please contact the resources sharing working group.
