| Abstract(in English) | We describe about an estimation method of loudspeaker direction. The method estimates the direction from level ratio between signals received by four microphones. The method is evaluated by simulations estimated from short segments of Japanese sentences every 0.2 seconds. A simulation results showed that estimation accuracies are 43.0%, 65.4%, 84.0% and 93.0% under the center frequencies i.e. 500Hz, 1000Hz, 2000Hz and 4000Hz of 1/3 octave bands. The most highest accuracy was achieved by the condition using 4000Hz as center frequency. |
