Recorded speech and written texts are increasingly presented as scientific evidence in legal cases. This is due to the fact that the accessibility and anonymity of mobile phones and the internet mean that they are often exploited for criminal acts, but at the same time they leave records which must then be analysed as forensic evidence. This has led to a rapid growth of forensic voice/text comparison as a field of forensic science. The theories and techniques, which are necessary to analyse linguistic evidence, are introduced and demonstrated, with a particular focus on voice and text as linguistic evidence, using examples taken from various languages. In this course, we overview the process of forensic voice/text comparison, including extraction of individualising information from speech/text samples; modelling of speakers/authors, experimental procedures; calculation of evidential strength and performance assessment. Students will be trained so that they can apply their acquired skills and knowledge to actual linguistic data.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

After successfully completing this course, students should be able to 1. Enhance the linguistic knowledge of the target language and beyond; 2. Explain the admissibility of scientific evidence; 3. Explain why the likelihood ratio-based framework is not only logically but also legally a correct way of analysing and presenting forensic evidence; 4. Understand the concept of likelihood ratio and Bayesian theorem; 5. Understand the nature of speech and text data as forensic evidence; 6. Extract individualising features from speech and text samples, and model them using appropriate statistical procedures; 7. Carry out forensic voice/text comparison tests; 8. Understand the concept of the metrics used in forensic voice/text comparison and appropriately use those metrics in the experiments; and 9. Understand and discuss the current issues surrounding forensic voice/text comparisons.

Staff Feedback

Students will be given feedback in the following forms in this course:

• Written comments
• Verbal comments
• Feedback to the whole class, to groups, to individuals, focus groups

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the ANU Online website Students may choose not to submit assessment items through Turnitin. In this instance you will be required to submit, alongside the assessment item itself, hard copies of all references included in the assessment item.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.

Participation

Students are expected to attend all classes, keep up with assigned readings, and contribute to class

discussions, as well as do the assignments given out.

Assessment Task 1

Paper summary/critical review assignment

Due: 11:55pm, Friday 22 March

Students will be given a journal paper and are asked to provide a one page summary/critical comment (should be more than 1000 words, but less than 1100 words) of the paper. Your submission must contain 1) a summary (c.a. 400 words) and 2) a critical comment (c.a. 600 words) of the paper. For writing critical reviews, please see: http://www.anu.edu.au/students/learning-development/writing-assessment/critical-reviews. A summative feedback will be given to the whole class together with individual written feedback by the end of Week 6.

Assessment Task 2

Take-home assignment 1

Due: 11:55pm, Friday 03 May

This take-home assignment is mainly on forensic voice comparison.

Individual feedback will be given. The course convenor endeavors to finish marking and return the assignment within two weeks after the submission due. Marks may be subject to moderation. This means that the raw score that you end up with at the end of the semester may not be your final mark.

Assessment Task 3

Take-home assignment 2

Due: 11:55pm, Friday 24 May

This take-home assignment is on forensic text comparison.

Individual feedback will be given. The course convenor endeavors to finish marking and return the assignments within two weeks after the submission due. Marks may be subject to moderation. This means that the raw score that you end up with at the end of the semester may not be your final mark.
