The ruling on using a recorder in the adhan to remind employees of the time for prayer

Question:
Also, our Shaykh, one of the brothers asks. He says: Shaykh Salih al-Fawzan, what is the ruling on using recorders and tapes for the adhan in government offices to remind employees and workers of the time for prayer, especially the Zuhr prayer? Is there any religious objection to this?

Answer:
This does not achieve the required and prescribed purpose. One person should call the adhan, or one employee or worker should be assigned to do so, and he should call the adhan with his own voice, because vocalizing the adhan is required and is an act of worship, and a recorder is not sufficient. Yes.
