A system capable of speech gap modulation, comprising a processing circuitry and configured to: (a) receive at least one composite speech portion, the at least one composite speech portion comprising at least one speech portion and at least one dynamic-gap portion, wherein the composite speech portion comprises at least one of input audio-format speech and input text-format speech, wherein the at least one speech portion comprising at least one variable-value speech portion, wherein the at least one dynamic-gap portion associated with a pause in speech; (b) receive at least one synchronization point, wherein the at least one synchronization point is associating a point in time in the at least one composite speech portion and a point in time in an at least one other media portion; and (c) modulate the at least one dynamic-gap portion, based at least partially on the at least one variable-value speech portion, and on the at least one synchronization point, thereby generating at least one modulated composite speech portion, wherein the modulation of the least one dynamic-gap portion comprises determining an estimated speech portion playback time of the at least one variable-value speech portion, wherein the modulation of the least one dynamic-gap portion comprises at least one of increasing gap playback time and decreasing gap playback time associated with the at least one dynamic-gap portion, wherein the at least one modulated composite speech portion comprises at least one of output audio-format speech and output text-format speech, thereby facilitating improved synchronization of the at least one modulated composite speech portion and the at least one other media portion at the at least one synchronization point, when combining the at least one other media portion and an audio-format modulated composite speech portion into a synchronized multimedia output. (a) receive at least one composite speech portion, the at least one composite speech portion comprising at least one speech portion and at least one dynamic-gap portion, wherein the composite speech portion comprises at least one of input audio-format speech and input text-format speech, wherein the at least one speech portion comprising at least one variable-value speech portion, wherein the at least one dynamic-gap portion associated with a pause in speech; wherein the composite speech portion comprises at least one of input audio-format speech and input text-format speech, wherein the at least one speech portion comprising at least one variable-value speech portion, wherein the at least one dynamic-gap portion associated with a pause in speech; (b) receive at least one synchronization point, wherein the at least one synchronization point is associating a point in time in the at least one composite speech portion and a point in time in an at least one other media portion; and (c) modulate the at least one dynamic-gap portion, based at least partially on the at least one variable-value speech portion, and on the at least one synchronization point, thereby generating at least one modulated composite speech portion, wherein the modulation of the least one dynamic-gap portion comprises determining an estimated speech portion playback time of the at least one variable-value speech portion, wherein the modulation of the least one dynamic-gap portion comprises at least one of increasing gap playback time and decreasing gap playback time associated with the at least one dynamic-gap portion, wherein the at least one modulated composite speech portion comprises at least one of output audio-format speech and output text-format speech, wherein the modulation of the least one dynamic-gap portion comprises at least one of increasing gap playback time and decreasing gap playback time associated with the at least one dynamic-gap portion, wherein the at least one modulated composite speech portion comprises at least one of output audio-format speech and output text-format speech, <EOS>
