Abstract: PROBLEM TO BE SOLVED: To provide a microphone-speaker integrated speech unit capable of detecting a direction of a sound source with high reliability. SOLUTION: A sound source unit direction particularizing processing means 255 detects a microphone which detects a highest level and a microphone which detects a second highest level (S311, 312). Further, a detection level difference between a pair of microphones is obtained (S313), whether or not the microphone adjacent to the microphone detecting the highest level detects the second highest level is checked, and in this case, whether or not the detection level difference between the pair of microphones is coincident with a prescribed pattern is checked. When coincident, it is determined that the sound source is present in the direction of the microphone detecting the highest level and the output of particularizing the direction of the sound source is provided (S321).
