In harsh channel conditions, the quality of the synthetic speech at low bit rate would be affected severely. In order to improve the robustness of the vocoder and make it more resilient to errors in random channel, unequal error protection (UEP) channel coding is usually adopted. However, when the errors cannot be corrected in some cases, UEP channel coding will not improve the quality of the synthetic...
With rapid development of information technology and upgrading of intelligent terminals, two-dimensional barcode has been widely used as a carrier to store, transfer and retrieve information. Due to the limited capacity, current two-dimensional barcodes are designed to embed text-only messages. In this paper, a generation method for acoustic two-dimensional barcode is proposed. It is based on speech...
In new generation networks like 3G wireless and VoIP, a great deal of emphasis is put on transcoder-free operation (TrFO), where speech remains coded throughout the core network. Any network-based speech processing function must, therefore, operate on the coded parameters directly if the value of TrFO is to be realized. Many of these functions, like echo control, noise reduction, and gain control...
