Latest Patents
Matsushima's latest patents include a voice communication system, a voice communication method, and a voice communication program. This voice communication system notifies a terminal device of transmission restriction information when the number of received voice signals reaches a predetermined number. A server device continuously counts the number of simultaneously received voice signals. A first terminal device transmits a voice signal with identification information of a second terminal device to the server. The server then transfers the voice signal to the second terminal device. However, when the number of simultaneous receptions reaches a predetermined restriction value, the server transfers the received voice signal with transmission restriction information attached. Consequently, the second terminal device does not transmit a voice signal, even if a user attempts to do so during the reception of the voice signal with the attached restriction information. Another notable patent is for a relaying device and monitoring method of voice communication. This device can track and record the communicated voice of a specific communication terminal using a mixing function. When a communication terminal sends a call packet to another terminal, a communication session is established. The relaying device records the voice signal transmitted to a virtual device registered as a participating terminal in the session.
