摘要
PROBLEM TO BE SOLVED: To provide a technology capable of obtaining two voice data with the noises reduced in a system in which a plurality of independent recording devices exist.SOLUTION: A first frequency analysis part 204 performs first frequency analysis to first voice data for each of a plurality of analysis ranges, and generates first result information indicating the result of first frequency analysis for each of the plurality of analysis ranges. A condition determination part 215 determines the analysis range under the consideration of first voice quality in the first voice data. A noise band detection part 213 detects a noise band for each of a plurality of analysis ranges on the basis of first result information and second result information. A first filter processing part 203 generates a first filter for filtering data of the noise band for each of the plurality of analysis ranges, and performs first filter processing by the first filter to the first voice data for each of the plurality of analysis ranges to generate third voice data.SELECTED DRAWING: Figure 2
