Unit description Unit description

Human speech makes use of the special acoustic properties of the vocal tract to generate the sounds of each language and to communicate them with an unlimited range of expression. In this unit, we explore the acoustic properties of speech which make this possible, and acoustic theories of speech production which describe its linguistic use. Topics include: general acoustics, source-filter theory, acoustics of vowels and consonants, acoustic description of Australian English and sounds in other languages, voice quality, speech variation, coarticulation, and prosody. Practical exercises include analysis of your own vowel space.

General Assessment Information

Grade descriptors and other information concerning grading are contained in the Macquarie University Assessment Policy.

All final grades are determined by a grading committee, in accordance with the Macquarie University Assessment Policy, and are not the sole responsibility of the Unit Convenor.

Students will be awarded a final grade and a mark which must correspond to the grade descriptors specified in the Assessment Procedure (clause 128).

To pass this unit, you must demonstrate sufficient evidence of achievement of the learning outcomes, meet any ungraded requirements, and achieve a final mark of 50 or better.

Further details for each assessment task will be available on iLearn.

Late Submissions

Unless a Special Consideration request has been submitted and approved, a 5% penalty (OF THE TOTAL POSSIBLE MARK) will be applied each day a written assessment is not submitted, up until the 7th day (including weekends). After the 7th day, a grade of ‘0’ will be awarded even if the assessment is submitted. Submission time for all written assessments is set at 11.55pm. A 1-hour grace period is provided to students who experience a technical concern.

Research Participation

Assessment Type 1: Participatory task
Indicative Time on Task 2: 1 hours
Due: Week 13
Weighting: 5%

 

Students will participate in a study to learn more about current research directions in speech and language, and to gain first-hand experience in the research process. Research participation typically involves one hour of your time. You will be able to choose from a short list of studies being conducted by researchers in Linguistics, Psychology, and Cognitive Science. If you do not wish to participate in any of the available studies, you will be given the option of completing an alternative assessment task to satisfy this component of the unit.

 


On successful completion you will be able to:
  • Engage in a research-rich environment.

Delivery and Resources

This unit is designed to foster a detailed understanding of speech acoustics, its relevance to phonetics and phonology, and methods used to study the acoustic properties of speech. These concepts will be studied through an extensive set of readings and multimedia resources, and will be consolidated in a series of companion lectures, workshops and assessment tasks. The unit provides students with essential theoretical and practical skills that are fundamental to further study of speech and which assist clinicians in keeping abreast of current research findings in speech and hearing.

Topics to be covered include: general acoustic theory; sound waves; spectrograms; resonance; turbulence; source-filter theory; formants; acoustic properties of vowels; acoustic properties of consonants; coarticulation; prosody; and digital representation of speech.

Students are required to engage seriously with all learning materials following the unit schedule provided on iLearn. Announcements and discussion forums should be consulted regularly, and recorded teaching materials must be reviewed in a timely manner to ensure that all participants in the unit are up-to-date with communications and aware of unit requirements. Active participation in the learning activities throughout the unit will require students to have access to a tablet, laptop or similar device. Students who do not own their own laptop computer may borrow one from the university library.

In workshops and assessment tasks, you will be presented with different types of speech data, and record your own speech for analysis, to consolidate your understanding of acoustic phonetics. These materials are designed to help you explore how speakers of different languages manipulate the acoustic properties of speech to generate phonological contrast, to signal linguistic information, and to communicate information about who we are.

Preparation for and attendance at all classes is expected. Classes are designed to consolidate concepts introduced in readings, through explanation and presentation of examples, engagement with different types of data, questions, discussion, and seminar-type exercises. Learning the concepts necessary to gain a solid understanding of speech acoustics and speech analysis techniques requires dedication, practice, and engagement. We are here to support your learning and we can only do this successfully through structured contact to guide you through the materials and techniques. It is your responsibility to actively engage in the learning process with your teachers and peers.

Inclusion and Diversity

Social inclusion at Macquarie University is about giving everyone who has the potential to benefit from higher education the opportunity to study at university, participate in campus life and flourish in their chosen field. The University has made significant moves to promote an equitable, diverse and exciting campus community for the benefit of staff and students. It is your responsibility to contribute towards the development of an inclusive culture and practice in the areas of learning and teaching, research, and service orientation and delivery. As a member of the Macquarie University community, you must not discriminate against or harass others based on their sex, gender, race, marital status, carers' responsibilities, disability, sexual orientation, age, political conviction or religious belief. All staff and students are expected to display appropriate behaviour that is conducive to a healthy learning environment for everyone.

Professionalism

In the Faculty of Medicine, Health and Human Sciences, professionalism is a key capability embedded in all our courses.

As part of developing professionalism, students are expected to attend all small group interactive sessions including clinical, practical, laboratory, work-integrated learning (e.g., PACE placements), and team-based learning activities. Some learning activities are recorded (e.g., face-to-face lectures), however you are encouraged to avoid relying upon such material as they do not recreate the whole learning experience and technical issues can and do occur. As an adult learner, we respect your decision to choose how you engage with your learning, but we would remind you that the learning opportunities we create for you have been done so to enable your success, and that by not engaging you may impact your ability to successfully complete this unit. We equally expect that you show respect for the academic staff who have worked hard to develop meaningful activities and prioritise your learning by communicating with them in advance if you are unable to attend a small group interactive session.

Another dimension of professionalism is having respect for your peers. It is the right of every student to learn in an environment that is free of disruption and distraction. Please arrive to all learning activities on time, and if you are unavoidably detained, please join activity as quietly as possible to minimise disruption. Phones and other electronic devices that produce noise and other distractions must be turned off prior to entering class. Where your own device (e.g., laptop) is being used for class-related activities, you are asked to close down all other applications to avoid distraction to you and others. Please treat your fellow students with the utmost respect. If you are uncomfortable participating in any specific activity, please let the relevant academic know.
