Can anyone point to information on the security and methods of solution
of voice scramblers which temporily reassemble segments of speech over
periods of the order of a second?

Is it known whether straightforward real-time solutions exist, or,
equivalently, is this a reasonable method for medium security 
(say, commercial) applications?

My question assumes the most for the security of the reassembly
sequence.
