The MSc programme combines a foundation in general linguistic-phonetic theory and method with extensive practical experience in analysis of forensic materials.
The MSc has been designed in conjunction with one of the world's leading forensic speech laboratories, JP French Associates. The director of the laboratory, Professor Peter French, will deliver some of the taught components and will supervise some research projects.
Students are given the opportunity to go on site visits that will allow them to observe the working practices of the laboratory, as well as those of cognate institutions such as courts. They will carry out analyses of recordings from real forensic cases and will have the opportunity to develop expert witness communication skills by undergoing cross-examination from a practising barrister in the University’s moot court.
Areas of the MSc overlap with those central to speech and recording technology and students will have the opportunity to gain hands-on experience of the latest generation of automatic speaker recognition software used in banking and law enforcement, made available through the Department’s partnership with Nuance.

STUDENTSHIPS: The Department is offering two studentships, each to the value of £3,500 towards course fees, for students who have no other funding. All such applicants currently holding offers of a place for 2017 will automatically be considered. The date for reviewing studentship applications is 30 March 2017.
The MSc in Forensic Speech Science provides a comprehensive foundation in the aims, practices, and principles of speech analysis for forensic purposes. The course will:
The course will be of interest to:
The Autumn Term provides a general introduction to linguistics (especially language variation), phonetics and acoustics. The typical Autumn term modules are:
The Spring Term comprises modules which enable students to expand their knowledge and skills in speech analysis, performing detailed work on a variety of recorded materials using a range of practical methods. There will also be forensics labs sessions which are not credit-bearing. The typical Spring Term modules are:
In the Summer Term students apply their knowledge and analytic skills to authentic forensic materials, with a focus on case work in speaker identification.
The programme is then completed by a research dissertation. However, the programme may be taken without the dissertation element for the award of a postgraduate diploma.
The MSc is not intended as a stand-alone vocational qualification. However, successful completion of the programme will provide students with the requisite skills, understanding, and knowledge to work effectively and increase their employability in forensic domains as well as in related fields such as the police, prison service, emergency call services and security services.
The MSc also provides distinctive training for students who wish to continue their academic careers to PhD level in phonetics, sociolinguistics/language variation and change, or acoustics.
Graduates of the MSc programme have found employment with police services, forensic laboratories, and as academic researchers.
The MSc qualification will equip students to apply for membership of the International Association for Forensic Phonetics and Acoustics.
Forensic speech science is the application of linguistics, phonetics and acoustics to legal investigations and proceedings.
Speaker comparison is the most common task in forensic speech analysis. It involves the comparison of speech patterns to assess the possibility of identity or non-identity of voices. Comparison is made by examining the phonetic, linguistic and acoustic components of the speech, and may be supplemented by automated procedures using speaker recognition technology.
Voices are highly variable, and comparison can be a very complex matter.
Disputed utterance examination involves analysis of problematic sections of recordings to determine what was said. There may be dispute, for example, because of noisy conditions, overlapping speech, accents, dialects, or even language.
Enhancement may be carried out to assist in this kind of work. Enhancement involves applying digital filters and dynamic processors to recordings to reduce background noise and improve intelligibility of speech.
Profiling involves analysis of recordings of unknown speakers to gain information about the regional and social background of the speaker.
Background noise may also provide information about where and when the recording was made.
Sometimes voice evidence can be crucial in a case even when it has not been recorded. A witness may have heard a voice but not seen the face of the speaker, for example if receiving abusive phone calls, witnessing a crime in the dark, or encountering masked robbers.
It is now generally accepted that witnesses must undergo formal testing in order to demonstrate their ability to recognise a particular voice. This is usually done via the construction of a voice "identification parade" in which the witness is asked to identify the criminal's voice within a group of foils.
Forensic speech analysts are also involved in general experimental work to test recognition and recall of voices.
Authentication involves examining recordings for evidence of editing or tampering, or assessing whether a recording has been made on a particular machine.
Some forensic cases involve analysis of recordings of non-speech sounds such as gun shots, machine noise or coughs.
In other cases sound propagation tests may be carried out, for example to assess whether a particular sound would have been audible to a witness at a particular location.
You should normally hold or expect to receive a good 2:1 or equivalent in your first degree.
If your first language is not English and your first degree was not taken in an English speaking country, you will need to show evidence that you meet our English Language requirements. We accept an IELTS score of 7, including 7 in both the written and oral assessment components. Full details of other accepted qualifications are given here.
You can apply for this course using our online application system. If you've not already done so, please read the application guidance first so that you understand the various steps in the application process.

I really enjoy the forensic laboratory sessions in which we are working with real case recordings.
