The performance of unreliable voice transmission (Voice over IP) over wireless links is measured not by the throughput but by the perceptual speech quality. The speech quality is impaired by packet losses, which are common on wireless links, and by high transmission delays. In this paper, we describe the design and implementation of a novel Speech Property Based Booster that improves the qualit...

This article presents a methodology for the preservation of audio documents, the operational protocol that acts the methodology, and an original open source software system that supports and automatizes several tasks along the process. The methodology is presented in the light of the ethical debate that has been challenging the international archival community for the last thirty years. The ope...

We propose to explore a new problem called audio-visual segmentation (AVS), in which the goal is output pixel-level map of object(s) that produce sound at time image frame. To facilitate this research, we construct first benchmark (AVSBench), providing pixel-wise annotations for sounding objects audible videos. Two settings are studied with benchmark: 1) semi-supervised single source and 2) ful...

Audio pattern recognition (APR) is an important research topic and can be applied to several fields related our lives. Therefore, accurate efficient APR systems need developed as they are useful in real applications. In this paper, we propose a new convolutional neural network (CNN) architecture method for improving the inference speed of CNN-based tasks. Moreover, using proposed method, improv...
