A speakerphone is a telephone feature that allows multiple people to hear and speak to each other during a call without needing to hold the phone. It uses a built-in microphone and speaker to amplify sound, making it easier for groups to participate in a conversation. Speakerphones are commonly used in business meetings, conference calls, or when hands-free communication is needed. They can be found on landline phones, mobile phones, and other communication devices, offering convenience for group discussions or when the user cannot hold the phone.
