Abstract
A voice signal may be adjusted to mask traits such as the gender of a speaker by separating source and filter components of a voice signal using cepstral analysis, adjusting the components based on pitch and formant parameters, and synthesizing a modified signal. Features are disclosed to support real-time voice masking in a computer network by limiting computational complexity and reducing delays in processing and transmission while maintaining signal quality.
