PROBLEM TO BE SOLVED: To smoothly perform the transmission and reception of voice data if a microphone is blocked, in television conference communication with an opposite terminal connected through a network.SOLUTION: A mobile terminal device outputs from a speaker 12 voice data received from the opposite terminal connected through the network, and also collects voice data output from the speaker 12 by a microphone 11. A correlation operation unit 34 performs correlation operation between the voice data output from the speaker 12 and voice data collected from the voice data, output from the speaker 11, by the microphone 11. A microphone block determination unit 35 determines whether or not the microphone 11 is in a blocked state, using the correlation operation result of the correlation operation unit 34. A warning unit 22 issues a notification that the microphone 11 is in the blocked state. |
