- VoiP: this utility is first and foremost a Voice Over Internet Protocol (VoiP). Like email or instant messaging software, Speak Freely enables to send and receive voice free of charge. This means that it can call anyone on its network.
- Half/Full-Duplex: communication is not simultaneous but in both direction. This means that Speak Freely is working as a walkie-talkie. There is no waste of the channel switching which is making it interesting. If the sound hardware is equipped with a full-duplex, there is an option to perform "conference calls" with this tool.

- It enables to communicate with other network audio programs.
- Speak Freely is downloadable free of charge.
- The interface is plain.
