One of the disadvantages of oral communication is that
immediate feedback is not possible
information could be denied
it is very expensive
it does not promote cordiality
Erläuterung
Oral communications are not easy to maintain and thus they are unsteady. There may be misunderstandings as the information is not and may lack essentials. It requires attentiveness and great receptivity on part of the receivers/audience.
