If this feature is enabled, you can initiate an intercom conversation with the last connected intercom friend by voice. When you want to start intercom, say a word such as “Hello” loudly or blow air into the microphone. If you start an intercom conversation by voice, the intercom terminates automatically when you and your intercom friend remain silent for 20 seconds. However, if you manually start an intercom conversation by tapping the Front Button, you have to terminate the intercom conversation manually.
However, if you start intercom by voice and end it manually by tapping the Front Button, you will not be able to start intercom by voice temporarily. In this case, you have to tap the Front Button to restart the intercom. This is to prevent repeated unintentional intercom connections by strong wind noise. After rebooting the 10U, you can start intercom by voice again.
