Published Thesis On Forensic Accounting

This article provides a primer on forensic voice comparison (aka forensic speaker recognition), a branch of forensic science in which the forensic practitioner analyzes a voice recording in order to provide an expert opinion that will help the trier-of-fact determine the identity of the speaker. Once the practitioner has specified the prosecution and defence hypotheses they have adopted, including the relevant population they have adopted, and has specified the type of measurements they will make, their task is to empirically calculate an estimate of a likelihood ratio which has a true but unknown value. Shepherd, smith, edward & kantas know the ins and outs of stockbroker conduct and law.

This amount would be deducted from the tuition fees for non ukeu students. The present paper argues that the courts opinion is based on misunderstandings of statistics and of the likelihood-ratio framework for the evaluation of evidence.

In order for a score-based approach to produce a forensically interpretable likelihood ratio, however, in addition to accounting for the similarity of the questioned sample with respect to the known sample, it must also account for the typicality of the questioned sample with respect to the relevant population. We believe that at this point there is no actual disagreement, and that both groups of authors are calling for greater collaboration in order to reduce the likelihood of future misunderstandings. The present study examines the strength of evidence which can be produced by a likelihood-ratio analysis based on the coefficients of polynomial curves fitted to the formant trajectories of australian english ai tokens.

Substantial improvements in validity were found for all supervisors systems, but some supervisors systems were more reliable than others. Forensic strength of evidence statements should preferably be likelihood ratios calculated using relevant data, quantitative measurements, and statistical models a response to lennard (2013) fingerprint identification how far have we come? Lennard (2013) fingerprint identification how far have we come? Aus j forensic sci. In 2015 the criminal practice directions (cpd) on admissibility of expert evidence in england & wales were revised.

Interpol survey of the use of speaker identification by law enforcement agencies morrison, g. The likelihood-ratio framework is a logical framework and not itself dependent on the use of objective measurements, databases, and statistical models. Durante los años 90 este nuevo paradigma se adopt ampliamente en la comparacin de los perfiles de adn, y se ha ido extendiendo gradualmente a otras ramas de las ciencias forenses, incluyendo la comparacin forense de la voz.

Acoustic-phonetic approaches to forensic voice comparison often include analysis of vowel formants. We also make a comparison with the performance of a procedure using a dichotomous matchnon-match similarity score, and compare the performance of 1 and 2 on real data. The mean procedure has a tendency to result in better accuracy, but the pooled procedure always results in better precision of the likelihood-ratio output. Distinguishing between forensic science and forensic pseudoscience testing of validity and reliability, and approaches to forensic voice comparison in this paper it is argued that one should not attempt to directly assess whether a forensic analysis technique is scientifically acceptable. The impact in forensic voice comparison of lack of calibration and of mismatched conditions between the known-speaker recording and the relevant-population sample recordings in a 2017 new south wales case, a forensic practitioner conducted a forensic voice comparison using a gaussian mixture model - universal background model (gmm-ubm).

    The study also assesses the validity of forensic-voice-comparison systems including a human-supervised and five fully-automatic formant trackers under landline-to-landline, mobile-to-mobile, and mobile-to-landline conditions, each of these matched with the same condition and mismatched with the high-quality condition.

The human-supervised systems always outperformed the fullyautomatic formant-tracker systems, but in some conditions the improvement was marginal and the cost of human-supervised formant-trajectory measurement probably not warranted. The thesis and two papers above use discriminant analysis to model perception data, a more appropriate technique would be logistic regression. All approaches require the forensic practitioner to use subjective judgement, but constraining subjective judgement to decisions relating to selection of hypotheses, properties to measure, training and test data to use, and statistical modelling procedures to use decisions which are remote from the output stage of the analysis will substantially reduce the potential for cognitive bias. Score based procedures for the calculation of forensic likelihood ratios scores should take account of both similarity and typicality score based procedures for the calculation of forensic likelihood ratios are popular across different branches of forensic science.

The present paper includes descriptions of the selection of the relevant hypotheses, sampling of data from the relevant population, simulation of suspect and offender recording conditions, and acoustic measurement and statisticalmodelling procedures.
