An audio conference system is a technology setup that enables multiple participants to engage in a voice-only communication session over a phone line or an internet connection. It is often used in business, education, and other professional settings to facilitate group discussions, meetings, and presentations without the need for participants to be physically present in the same location.

Overall, an audio conference system is a practical solution for enabling real-time voice communication among multiple participants, enhancing collaboration and decision-making in various contexts.
