Conference interpretation is an oral intellectual exercise, quite distinct from drafting a written text.
Interpreters work in the heat of debate, thinking as they speak.
In most cases, it is probably easier to record the papers and discussions in the original language and to use the services of a translator afterwards if necessary. Intellectual and creative works and their use by third parties are protected by national legislation, bilateral and international agreements, in particular the International Copyright Convention and the Berne Convention for the Protection of Artistic and Literary Works. Conference organisers who wish to record the interpretation should therefore consult the interpreters.
