SELT Survey Results

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.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills 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 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

Student Feedback

ANU 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.

Other Information

Graduate students attend joint classes with undergraduates but are assessed separately.
