In mobile speech communications, because of the noise interfering with speech at one end, the intelligibility of speech degrades at the other end. In this paper, we focus on suppression of noise produced by vehicular and automobile mechanical engines, in whose presence the intelligibility of the speech deteriorates, when transmitted to the other end (or) while recording. We propose a method using...
There have been several methods to enhance the speech corrupted by echo and broadband noise. Predominantly speech enhancement can be categorized as echo cancellation and noise reduction. Several techniques were introduced to reduce various kinds of background noise and echo; some frequency techniques are based on spectral subtraction. In any mobile communication system (uplink or downlink) the corrupted...
We explore the impact of the playout buffer size on the video quality and the response time in a video streaming application. Large buffer generally improves video quality, since it accommodates wide range of rate variability. However it incurs large buffering delay, and it is not suitable for many streaming applications (e.g., video sharing). In this paper, we investigate the playout buffer requirement...
