In this paper, we propose a method to provide speech privacy by deforming the frequency characteristics of the voice. An active noise control is used in this method. Major factor determining the phonological in speech recognition is relative relationship of the feature quantity of speech called formant frequency. Breaking this relationship by control in the frequency domain, performs speech masking making it difficult to recognize phonemes. With to verify the control effect by the simulation, to examine the effectiveness of the proposed method by evaluation using quantitative indicators.
