ASA states in their case book that there CANNOT be verbal obstruction. However, there can be verbal interference.
Actually, the case book, at least back to 2007, makes no such statement.
I does give an example of defenders and a defensive coach screaming "go" prior to a ball being caught by F9 in order to get an appeal for leaving too soon. The justification was that the runner should recognize their own coach's voice and instructions.
That gives one simple scenario. It does not exclude all possible scenarios.
