Distribution servers of this kind do already exist for special scientific speech data and are usually free to use. They require a considerable effort to set up and maintain.
For speech resources that are not absolutely freely available there are still many practical and legal problems to solve.
We recommend allowing the free download of the meta data and perhaps also of the annotation data of a speech corpus. Meta data are essential for prospective users to help them decide whether a speech resource meets their special needs. Annotation data are in most cases of not much use for commercial users without the corresponding signal data, but they might be of academic interest.
