pre-recorded template that stores each speaker’s distinctive features. We will use this template to do a mix and match with the speakers in our system. Speaker identification refers to the process of identifying an individual by extracting and processing information from his speech. This is a fascinating area of research. From speech itself‚ we can deduce quite accurately whether the speaker is male or female‚ adult or child. It is also possible to detect the emotional state‚ and attitude of

INTRODUCTION SPECTRUM ESTIMATION is an important application of the Digital Signal Processing. Spectral analysis is used in many applications such as to get the target location and its velocity information in the radar applications [9]. In general many practical applications such as Ocean noise‚ Wind speed give a time series data

How to get the best results from VoIP In this project‚ the discussion will be on how to get the best results from VoIP. Firstly‚ use the four basic rules in selecting the right Codec. Rule one; using band with 64k or less one must use G.729‚ G. in choosing 723 or alternative one determines the right Codec to use for VoIP? In making the choice of what codec to use in VoIP‚ low bandwidth codec. Rule two; use the best codec possible by decreasing the Mean Opinion Score. Rule three; Use of more

Filtering of the speech signal is one way to increase the difficulty of the perceptual task. Filtered speech has the ability to decrease the redundancy of the speech signal and increase the sensitivity to the brain lesion. The listener’s performance will be significantly worse on a filtered Speech recognition task than on an unfiltered speech recognition task because the CANS would be incapable of compensating for the missing information with a breakdown of redundancy of the CANS (lesion). The filtered

communications curriculum. Most modern communications curriculum at the undergraduate level have a networking course hence no coverage is given for networking. For communications majors it is expected that this course will be followed by a course in digital communications (EE702). The course objectives for EE501 that can be taught from this text are (along with their ABET criteria) 1. Students learn the bandpass representation for carrier modulated signals. (Criterion 3(a)) 2. Students engage in engineering

Modulation 2. Upper Side Band (USB) Modulation FM [3]Frequency modulation (FM) is a method of impressing data onto an alternating-current (AC) wave by varying the instantaneous frequency of the wave. This scheme can be used with analog or digital data. Frequency modulation is similar in practice to phase modulation (PM). When the instantaneous frequency of a carrier is varied‚ the instantaneous phase changes as well. The converse also holds: When the instantaneous phase is varied‚ the instantaneous
