Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

1. INTRODUCTION
A machine can be considered intelligent if a human judge involved in a natural conversation with a human and the machine, cannot distinguish between the two. The field of artificial intelligence thus has its roots in making machines human-like, with the ability to perceive, analyze and respond to their surroundings in a way that is natural and seamless to humans. Since human perception is multimodal in nature, with speech and vision being the primary senses, significant research effort has been focu ....etc

Welcome to the world of intelligent speech processing!! Ordinary Automatic speech recognition systems use only audio information for speech processing. On the contrary, human speech is bimodal in nature. It consists of two main parts ? audio and video information. Audio information is the usual speech signal that we receive. Video signal consists of the lip movements and other visual information. The relevant data in a video signal is isolated and features are extracted from it. From a series of feature vectors, we make a set of higher set of s ....etc

INTRODUCTION

Demodulating a signal decomposes it into a slowly varying temporal envelope and a rapidly varying cosine (or fine structure--related to the instantaneous frequency of the signal). The motivation in representing a signal by envelope and fine structure comes from our desire to understand an ....etc

Evaluating Existing Audio CAPTCHAs and an Interface Optimized for Non-Visual Use




INTRODUCTION AND MOTIVATION

The goal of a CAPTCHA1 is to dierentiate humans
from automated agents by requesting the solution to a
problem that is easy for humans but dicult for com-
puters. CAPTCHAs are used to guard access to web re-
sources and, therefore, prevent automated agents


Making CAPTCHAs Accessible

Audio CAPTCHAs were introduced soon after their vi-
sual alterna ....etc
