12. The non-transitory processor readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to: receive a signal associated with a sound detected by a microphone; identify a pause associated with a human associated with a human voice from the sound not speaking; generate a masking language including a plurality of phonemes and a matrix-filling sound; combine a matrix-filling sound with the masking language a timing of the matrix-filling sound associated with a timing of the pause; and transmit a signal representing the matrix-filling sound and masking language to a speaker after combining the matrix-filling sound with the masking language.
12. The non-transitory processor readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to: receive a signal associated with a sound detected by a microphone; identify a pause associated with a human associated with a human voice from the sound not speaking; generate a masking language including a plurality of phonemes and a matrix-filling sound; combine a matrix-filling sound with the masking language a timing of the matrix-filling sound associated with a timing of the pause; and transmit a signal representing the matrix-filling sound and masking language to a speaker after combining the matrix-filling sound with the masking language. 13. The non-transitory processor readable medium of claim 12 , wherein the masking language is a first masking language, and the speaker is a first speaker, the code further comprising code to cause the processor to: identify a feature associated with a human voice from the sound, at least a phoneme from the plurality of phonemes matching the feature; generate a second masking language based on the first masking language, at least a component of the second making language shifted in at least one of volume, frequency, or time relative to the first making language; and transmit a signal representing the second masking language to a second speaker.
