Purpose/Description:
        The purpose of this course is to provide the students with basic
information concerning the scientific bases of human speech production and
perception.  A basic understanding of the scientific processes of speech
production and speech perception are essential to students in our field
whether their ultimate goals are to be teachers, researchers, clinicians,
or some combination of these three professional interests.   This course is
a study of the production, transmission, and perception of speech signals;
anatomy, physiology, phonetics, acoustics, psychoacoustics, and acoustic
cues.  This course also includes lab experience and clinical applications.
Whenever it is relevant, multicultural aspects pertaining to the topics of
study will also be discussed.

Course Objectives:
        Upon successful completion  of this course, the student will be
able to:
- discuss relation between acoustics, speech science, speech production,
and speech perception.
- explain acoustic parameters of sound/speech and how they relate to
physiological changes.
- explain acoustic parameters of hearing and how they relate to speech.
- describe the anatomical components of respiration, phonation, and
articulation; explain how   these systems work together for the production
of speech; relate the information for phonation and articulation to the
parameters of frequency, intensity, and duration; and discuss appropriate
theories concerned with the physiological operations of these systems
during the speech production process.
- discuss the source-filter theory of vowel production.
- describe models/theories of speech production and speech perception.
- describe the acoustic cues for the speech sounds of English; and explain
the cues in terms of manner of production, place of articulation, and
suprasegmental influences.
- develop an awareness of technological applications as they relate to
analysis of speech.

Exams & Requirements:
        There will be a total of three exams.  The final exam will be held on ... The final exam will be a comprehensive one.  The first exam will account for 75 points.  The second and the final exams will account for 100 points each.  If there is a change
in the scheduling of the exams, it will be announced by the instructor well in advance.
        In addition to the above, practicum and lab work are essential.
The practicum and lab work will include the exercises and instrumentation
used in the fields of speech science and perception.  The projects in the
lab will account for 25 points.  The project reports are to be turned in on
time.  The project reports are due on the following week from the day they
are assigned.  Thus, you will have at least one week to complete a project
report.   Project reports turned in late will be lowered by 25% of the
total points designated for that particular project.
        Students are responsible for all materials, assignments, etc.
presented in the class by the instructor.  If you miss a class it is your
responsibility to make up for that class missed.

Grading:
        Final Class Grades will be determined by the number of points
obtained out of the possible 300 points.
        Grading Scale - 93-100 = A
                                85-92   = B
                                77-84   = C
                                66-76   = D
                                <65      = F
Pass/Fail Information:
        Graduate students have the option of registering on a pass/fail
basis for courses not included in their degree plan.  Courses on a
pass/fail basis may not be used for degree credit at SLU.  For credit
courses, a grade of P will be assigned only if the work is of at least C
quality.

Professional Standards:
        Students are expected to maintain professional standards of
behavior at all times when fulfilling course requirements.  Free
discussion, inquiry, and expression is encouraged in this class.  Classroom
behavior that interferes with either (a) the instructor's ability to
conduct the class or (b) the ability of students to benefit from the
instruction is not acceptable.  Examples may include routinely entering
class late or departing early; use of beepers/cellular phones, or other
electronic devices; repeatedly talking in class without being recognized;
talking while others are speaking; or arguing in a way that is perceived as
"crossing the civility line".  In the event of a situation where a student
legitimately needs to carry a beeper/cellular phone to class, prior notice
and approval of the instructor is required.
        Students must demonstrate proficiency in written composition as
written communication skills are basic to professional
communication/activities.  The written component of
examinations/assignments will be graded on correctness of usage, word
choice, spelling, punctuation, organization, neatness, as well as content.
        Students should consult the current catalogue for information
regarding the last day to drop or resign from the university without grade
penalty.  Students are responsible for completing required forms when they
find it necessary to discontinue university work prior to the end of the
semester.
       Tape recording of the lectures/class presentations is not permitted
unless prior permission to do so is taken from the instructor.
        Students will not be given make-up exams without a valid written
excuse for the absence.  If a student is too sick and unable to take an
exam,  she/he should bring a note from her/his physician which can be
verified by the instructor.  Without such a valid written note there can be
no excused absences from an exam.  Any student who is excused from an exam
will be able to take a make-up exam until the time the original test is
returned to the entire class.  Once a test has been returned, make-ups are
no longer possible.  In such situations, alternate arrangements will be
made on a case by case basis.  The make-up exam will be in the form of oral
exams.
        If you are a qualified student with a disability seeking
accommodations under the Americans with Disabilities Act, you are required
to self-identify with the Office of Student Life, Room 202, Student Union.
