Interleaving has shown to be a useful technique to provide robust distributed speech recognition over IP networks. This is due to its ability to disperse consecutive losses. However, this ability is related to the delay introduced by the interleaver. In this work, we propose a novel multi-flow block interleaver which exploits the presence of several streams and allows to reduce the involved delay. Experimental results have shown that this interleaver approximates the performance of end-to-end interleavers but with a fraction of their delay. As disadvantage, this interleaver must be placed in a common node where more than one flow are available.
