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 can then be analysed as forensic evidence. This has led to the 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 are expected to demonstrate that they can appropriately apply their acquired skills and knowledge to actual linguistic data extracted from various languages, and then that they can provide an in-depth analysis of the data. They are also expected to critically discuss the results of the analysis by referring to the current issues of forensic voice/text comparison.
Upon successful completion, students will have the knowledge and skills to:
Upon completion of this course, students should be able to:
1. Critically evaluate different methodologies used in forensic voice/text comparisons;
2. Demonstrate high level analytical skills required for forensic voice/text comparisons;
3. Carry out forensic voice/text comparison experiments with a small set of data;
4. Present the outcomes in a written and/or oral format;
5. Critically examine readings on the current issues surrounding forensic voice/text comparisons; and
6. Exercise higher-level critical thinking and judgment in identifying and solving problems related to forensic voice/text comparisons.
Staff FeedbackStudents 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
Student FeedbackANU is committed to the demonstration of educational excellence and regularly seeks feedback from students. Students are encouraged to offer feedback directly to their Course Convener or through their College and Course representatives (if applicable). The feedback given in these surveys is anonymous and provides the Colleges, University Education Committee and Academic Board with opportunities to recognise excellent teaching, and opportunities for improvement. The Surveys and Evaluation website provides more information on student surveys at ANU and reports on the feedback provided on ANU courses.

PoliciesANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:
Assessment RequirementsThe 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 AssessmentMarks 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.
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
Learning Outcomes: 1,2,5,6
Paper summary/critical review and bibliography/annotation assignment
Due: 11:55pm, Friday 19 March
This assignment consists of two parts: i) paper summary/critical review and ii) bibliography/annotation assignment.
- First part: paper critical review assignment
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) critical comments (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.
- Second part: bibliography/annotation assignment:
Using the keywords relating to forensic voice/text comparison, compile a bibliography of 10 peer-reviewed journal articles, using Google scholar. Your keyword can be anything on forensic voice/text comparison, but it is better if you have a specific topic of forensic voice/text comparison. Consult the course convener about your topic no later than Week 3. Failure to do so will result in a deduction of your mark (-10%). From the compiled bibliography, choose one paper and provide a critical annotation for it (should be more than 1000 words, but less than 1100 words). A critical annotation should contain:
- Summary of the paper (ca. 400 words)
- Critical review of the paper (ca. 600 words)
When you write up a critical review, think about how you could have done/written the same research better. Criticise the papers as much as you can. A summative feedback will be given to the whole class together with individual written feedback by the end of Week 6.
Assessment Task 2
Learning Outcomes: 1,2,3,4,6
Take-home assignment 1
Due: 11:55pm, Friday 30 April
This take-home assignment is mainly on forensic voice comparison. A more detailed instruction will be given on Wattle. 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. This assignment is a hurdle assessment.
Assessment Task 3
Learning Outcomes: 1,2,3,4,6
Take-home assignment 2
Due: 11:55pm, Friday 21 May
This take-home assignment is on forensic text comparison. A more detailed instruction will be given on Wattle. 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. This assignment is a hurdle assessment.
Assessment Task 4
Learning Outcomes: 1,2,6
Date: TBA (Check the exam timetable)
A two~three hour-long final exam (take-home) will also be held during the examination period. Students are required to be and available for the duration of the examination period. You should not make any external commitments or travel plans during this time. A more detailed instruction will be given on Wattle. The final exam is a hurdle assessment.
