Auto voice calls refer to automated phone calls that are initiated using software and do not require a live operator to make the call. These calls are often used for mass communication purposes, such as marketing campaigns, political surveys, appointment reminders, and more.

Auto voice calls can be made using a computer or a specialized auto dialing system that can automatically call a list of phone numbers and play a pre-recorded message. Some auto voice call systems also have the capability to detect voicemail and answer machines, and can leave a pre-recorded message or transfer the call to a live operator if necessary.
