    Patent number: 7158645
    Abstract: Provided are an orthogonal circular microphone array system for detecting a three-dimensional direction of a sound source, the system comprising a directional microphone which receives a speech signal from the sound source, a first microphone array in which a predetermined number of microphones for receiving the speech signal from the sound source are arranged around the directional microphone, a second microphone array in which a predetermined number of microphones for receiving the-speech signal from the sound source are arranged around the directional microphone so as to be orthogonal to the first microphone array, a direction detection unit which receives signals from the first and second microphone arrays, discriminates whether the signals are speech signals and estimates the location of the sound source, a rotation controller which changes the direction of the first microphone array, the second microphone array, and the directional microphone according to the location of the sound source estimated by th
