Abstract

See full text

Methods and apparatus to provide speech privacy are disclosed. An example method includes forming a sampling block based on a first received audio sample, the sampling block representing speech of a user, creating, with a processor, a mask based on the sampling block, the mask to reduce the intelligibility of the speech of the user, wherein the mask is created by converting the sampling block from a time domain to a frequency domain to form a frequency domain sampling block, identifying a first peak within the frequency domain sampling block, demodulating the frequency domain sampling block at the first peak to form a first envelope of the sampling block, distorting the first envelope to form a first distorted envelope, and emitting an acoustic representation of the mask via a speaker.
