It is known that speech remains intelligible when it is interrupted at a slow rate (about 50 cps). Such interruption reduces the time duration of transmission without increasing the bandwidth and, hence, can increase the effective utilization of a communication channel. The reasons for the intelligibility of interrupted speech are explained, and the theoretical limits to the interruption rate and sampling period are estimated. Interrupted speech, even if it does not reduce the information content appreciably, will still not be directly suitable for communication purposes because of switching noise. Three methods for overcoming this noise, namely, by reverberation, by integration, and by the reiteration of synchronized speech samples are described. It is shown that there is a possibility of increasing the efficiency of speech communication by a factor of at least two, perhaps, as much as ten times. |
