As most PCs are laptops and all of these have microphone for videoconference and a lot of people use earphone or similar allways for meeting, why do not use the voice to look for a document, a practice or to move on in a workflow?
With the introduction of A.I. in a DMS system it is no longer necessary to have structured data such as indexes. Then look for a document or go to the workflow steps just with the voice, it may be more efficient.
