It came as news to me recently that the technology exists to search the spoken word in much the same way as e-discovery tools search the written word.
Bearing in mind the wide definition of “document” for the purposes of disclosure, lawyers need to consider whether voicemails and recorded messages and other forms of the spoken word should be disclosed. Basically, speech recognition companies offer a “culling” system similar to e-discovery by using search terms to pull out responsive material from audio tapes.
