Abstract

This paper examines the level of awareness and utilization of forensic linguistic services in the Nigeria justice dispensation system. It surveys the employment of forensic linguistic services during interrogation and cross-examination of crime suspects in Police stations and law courts, respectively, as well as the admissibility of forensic linguistic evidences in courts. Data for the study were gathered from security and legal personnel in police stations, law chambers and courts with questionnaires. Data analysis was done by a simple statistical method. The study finds that the level of awareness about Forensic Linguistics among police and other legal personnel is high, even though only a few of them have ever consulted or worked with any. They however submitted that forensic linguist' evaluation and advise are useful and will make their work easier, and that forensic linguistic evidences are admissible in the Nigerian courts. The study recommended, among others, that Forensic Linguistics programs should be established in Nigerian universities to enhance its practice of among the people.

Abstract

There is still much to learn about speakers’ similarities and differences in the field of Forensic Phonetics with respect to consonant acoustics. This article analyses of acoustic features of three sibilants /s, z, ʃ/ in British English. The analyses have been carried out on twenty male speakers from the DyViS corpus focusing on static features (intensity, centre of gravity, standard deviation, skewness and kurtosis) and dynamic features (centre of gravity depending on F2 vowel onset and offset) to see if they cue speaker-specific information. The results obtained demonstrate the high speaker-specificity of centre of gravity, standard deviation and intensity. However, we must be careful with intensity because it depends on the recording circumstances. As for skewness and kurtosis, they show speaker-specificity for /z/, but results are weaker the other two. This article has shown that spectral and acoustic properties of these three sibilants in English present promising results.

Abstract

This thesis is intended to analyze the implementation of the forensic method using voice recognition technique to analyze voice resemblance towards mobile phone’s voice recorder, by using Forensic audio method In Audio forensics: Theory and Analysis, namely Pitch Statistical Analysis, Forman and Bandwidth Statistical Analysis, Graphical Distribution Analysis and Spectogram Analysis. However, in this study, researchers only focus on identifying pitch and formants in the data to be analyzed. The aims of this study is to provide an example scenario the application of digital forensic techniques for voice pain recognizes Greetings compare the sound in the evidence and the sound suspect on mobile phone media with a voice case study woman. So it is hoped that the output of this research can become a reference or enrichment material for law enforcement agencies law and academics who wish to continue their research related to digital forensics. In doing on In this study, a Praat application was used to help with the audio comparison process from Known Samples and Unknown Sample. The results of each sample of digital evidence of native speakers' voices and recorded comparisons on the two assessment factors, namely Pitch and Formant, the researcher can't distinguish between the original speaker's voice and the comparison voice. The researcher can state that the accuracy of the pitch and formant analysis through Praat is very low and cannot be used as an indicator to distinguish that a date is correct as of the original voice, as evidenced by the results of the F0 value of the original voice data and the comparison obtained. Very flexible and inconsistent, some are the same, close to and even far from the F0 value of the subject data. This shows that everyone has a different pitch value because the intonation of each person's word pronunciation is different. It is possible that there are pitch values from several subjects that are almost the same.
