Intelligibility Evaluation of a VoIP Multi-flow Block Interleaver

چکیده
This work contributes to demonstrate what perceptual benefits can be expected by adding some processing capabilities to the network nodes for the class of interactive audio streaming applications. In particular, we propose a new voice stream multi-flow block interleaver and we show that it provides an intelligibility performance very close to the reference end-to-end interleaver, even under conditions where the end-to-end interleaving is unfeasible.

Multi-flow Block Interleaving app Recognition over IP
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 del...
متن کاملEfficient Signal Quality Improvement Approach for Wideband VoIP System in Pervasive Environment
-Voice over Internet Protocol (VoIP) is a the best alternative to the traditional voice communication system, since VoIP system converges the data, voice and video data and reduces the cost of call transmission by passing packets through the available bandwidth through internet protocol. Since the environmental noise may affect the intelligibility of the speech signal, so it is desirable to use...
متن کاملDetecting VoIP Traffic Based on Human Conversation Patterns
Owing to the enormous growth of VoIP applications, an effective means of identifying VoIP is now essential for managing a number of network traffic issues, such as reserving bandwidth for VoIP traffic, assigning high priority for VoIP flows, or blocking VoIP calls to certain destinations. Because the protocols, port numbers, and codecs used by VoIP services are shifting toward proprietary, encr...
متن کاملLow Complexity Multi Mode Interleaver Core for WiMAX with Support for Convolutional Interleaving
A hardware efficient, multi mode, re-configurable architecture of interleaver/de-interleaver for multiple standards, like DVB, WiMAX and WLAN is presented. The interleavers consume a large part of silicon area when implemented by using conventional methods as they use memories to store permutation patterns. In addition, different types of interleavers in different standards cannot share the har...
متن کاملNumerical Investigation on Compressible Flow Characteristics in Axial Compressors Using a Multi Block Finite Volume Scheme
An unsteady two-dimensional numerical investigation was performed on the viscous flow passing through a multi-blade cascade. A Cartesian finite-volume approach was employed and it was linked to Van-Leer's and Roe's flux splitting schemes to evaluate inviscid flux terms. To prevent the oscillatory behavior of numerical results and to increase the accuracy, Monotonic Upstream Scheme for Conservat...
