Over the recent years we have worked with multiple databases for speech recognition. As we want to share our efforts, you can download these automatic sign language recognition databases used at our institute from our FTP server. Yet, there are several things to consider:

• You'll have to agree on our license conditions. Please acknowledge that these databases are not intended for commercial usage and are hence not allowed to be used for that purpose.

• As we are curious who uses our databases and for internal tracking, we request you to fill a form before you can download our databases. The hereby collected data is stored for no other purpose than internal tracking and is not transmitted to third parties.

Thanks for being interested in downloading RWTH-Phoenix-Weather. As explained above, we request you to fill this form. The hereby collected data is stored securly and not transmitted to third parties.
