In the future it would be nice to be able to add custom example sentences with audio.
I read that a future implementation may support tatoeba, but this would be a problem for audio that has copyright.
In cases where we bought a book (for example) with audio CD's, we are entitled to make personal recordings under copyright "fair use" for educational purposes, however we are not allowed to publish them. So, uploading the audio with the sample sentence to Tatoeba is not an option.
It would be great to be able to study the words in the context of the course materials that we are using. This would be invaluable for comprehension exercises.
I understand that this might require allocating storage for each user, which might be prohibitive.
A couple of alternatives spring to mind, would it be possible to reference audio sample files on local disks?
A completely seperate approach would be to choose a good comprehension text-book or audio-book and licence it for all users. This might actually appeal to a number of publishers, as it would encourage demand for their books.
I think Skritter is a superb tool. With support for comprehension it would make a complete self-study system.
