Additional
reading may be assigned.
Students with
Disabilities: If you have a specific disability that
qualifies you for academic accommodations, please notify the instructor and
provide certification from Disability Services in the Office of Special Student
Services. The Office of Special Student Services is located in Room 270 of the
Notice About HIPAA regulations: The USA Speech
and Hearing Center is compliant with the Privacy Rules of the Health Insurance
Portability and Accountability Act of 1996 (HIPAA). As part of this class, you may be required to
directly and/or indirectly observe therapy procedures conducted with actual
clients. Direct observations will take
place in our Clinic; whereas, indirect observations may be offered through the
use of videotaped therapy sessions which are shown during class time. In compliance with HIPAA, the patients and/or
patient representatives have given authorization to allow for the
observations. Additionally, the amount
of Protected Health Information (PHI) that is provided to you will be limited
to the “minimum necessary.” We require
you, as future professionals in the field of Speech Pathology and Audiology, to
be respectful of the learning opportunity afforded to you through these
observations.
Course Objectives/Goals:
To provide a
meaningful experience in the study of speech science through lecture,
demonstration, laboratories and textbook study.
To enhance the
student's knowledge of the physiologic and acoustic bases of sound and it's
measurement.
To enhance the
student's knowledge of instrumentation used in the measurement of speech.
To provide
basic understanding of psychoacoustic principles.
To provide
basic understanding of speech perception principles.
Course Content:
1.
Introduction, Speech Chain, Exponents, Metric System, Basic Acoustics, Sound
propagation
2. Basic Acoustics,
Simple Harmonic Motion, Resonance, Physiology of the Speech Producing
Mechanisms
3. Acoustics of
Speech, articulation, resonance
4. Filtering,
Spectrograms, Feedback, Suprasegmentals
5. Speech
Production Theories
6. Introduction
to psychoacoustics, Psychophysical testing, Scaling, measurement variables
7. Masking,
critical bands. Non-linear systems, Binaural hearing, Pitch perception,
Adaption
8. Acoustic
cues to perception, Theories of speech perception
Additional Course Requirements: In addition to class lectures, there are
speech production and perception laboratory requirements. The first will
involve spectrographic identification of sound components for various stimuli
and the second will involve the recording of acoustic stimuli, manipulation of
the stimuli, presentation of stimuli to listeners, and a written report
describing the correlation of the acoustic presentations with listener
perceptions. Students will work in groups for the second assignment. Time for
the laboratories will not be incorporated into class time.
Behaviorally
defined objectives for student knowledge and skill:
Each of the
objectives below describes the behavior to be achieved and the mechanism for
evaluation.
The student
(with a partner) will compare a pre-recorded sentence produced by a dysarthric
speaker with a sentence recorded by the student. The student will produce a
written summary of similarities and differences in acoustic and perceptual
information between the speakers. Acoustic information will be obtained from
spectrograms generated by the student. The report is to include differences in
vocal tract control that result in the acoustic and perceptual judgements.
(Addresses SLP ASHA standards III-A, III-B, III-C (articulation, voice and
resonance, expressive language), III-D (articulation, voice and resonance,
expressive language), AUD ASHA standards B7 (
The student
(with other partners) will complete a lab that will involve the production of
acoustic recordings of a set of syllables, a listening component to identify
undegraded and degraded syllables, and a written summary that reconciles the
listener responses to the undegraded and degraded syllables with spectrograms
generated from representative syllables. (Addresses SLP ASHA standards III-A,
III-B, AUD ASHA standard B7, B9 (Principles, methods, and applications of
psychoacoustics), B13).
The student will
pass a final exam covering semester content regarding speech production,
psychoacoustics and speech perception. (Addresses SLP ASHA standard III-A,
III-B, III-C, AUD ASHA standard B7, B9, B13).
Evaluation: Grades for this
class will be determined from scores obtained for the midterm examination, the
final examination and the laboratory assignment. The breakdown is as follows:
Midterm examination: 30%
Final examination: 40%
Laboratory assignments 30%
Grades for this
course are applied as follows:
Grade A: 90 - 100%
Grade B: 80 - 89%
Grade C: 75 - 79%
Grade D: 68 - 74%
Fail: below 68%
Students should
be advised that they are required to maintain a 3.0 GPA in order to continue in
the graduate program.
Plans for Record
Keeping, Feedback to Students, Faculty, Supervisors, & Student Remediation: Grades for
assignments are kept on a spreadsheet by the instructor. Completed assignments
are returned to the students with instructor feedback at every step of the
prospectus. The instructor meets regularly with students (individually or in
small groups) to discuss progress. Instructor and faculty mentoring of student
progress forgoes the need for remediation. Faculty mentors for student projects
are informed of student progress as needed. Students who perform poorly on the
final exam are required to rewrite portions to demonstrate knowledge and skill
acquisition to instructor’s satisfaction. Students are assigned a final course
grade.
Statement on
Changes in Course Assignments: Any changes in the course assignments
will be made in a timely manner and students will be notified of the changes
during class meetings.
Attendance
Policy:
Graduate level study is the final preparation before students enter the
profession. As such, students should
consider class attendance to be similar to attendance in a professional
setting. It is mandatory. Students will be allowed one unexcused
absence during the lecture series.
Subsequent unexcused absences will be penalized by a drop of one letter
grade per absence. Absences during exam
periods or during the class presentations must be accounted for by appropriate
documentation such as a doctor’s notice of illness. Students are advised that
they are allowed only one grade of C before being dismissed from the program.
For absences of
two or more consecutive class meetings due to illness, death in the family, or
family emergency, students should contact the Vice President for Student Affairs.
Absence notices will be sent to each instructor notifying him/her of the reason
for the approximate length of absence. This notification does not constitute an
excused absence.
