Abstract
Abstract: The area of forensic speech and audio analysis encompasses a vast range of operations, the much more prominent of which is, without the need of a doubt, speaker identification. In addition, comprehensibility improvement of the recorded voice signal, analysis of disputed speech, and assessment of the legitimacy of audio recordings are also activities in the field. Using voice analysis, the examiner has two ideas about how to make an identification. Initially, he or she might compare the accent, conversational habits, breathing rhythms, and intonations of the evidence sample with the suspicious samples. After then, the corresponding voiceprints are compared. Voice parametrization is the process of converting a voice signal into a set of selected features that emphasize the speaker unique characteristics. The goal of this modification is to establish a new depiction that is more concise and more appropriate to speaker characterization. While evaluating deteriorated acoustic situations, recognizing voice parts becomes challenging. Time interval measure, zero-crossing rate, pitched spectrum analysis, higher cognitive statistics in the LPC residual domain, and fusions of various characteristics are among the Voice Activity Detection (VAD) approaches employed.
