Overview of the Class

In this course you will learn the fundamentals of human and speech . You will learn how the produces the energy source for production; how the laryngeal system valves this airflow into a voiced sound source; vocal tract and physiology; what theoretical issues drive speech motor control research; what sound waves are and how they are captured by spectrograms; how phoneme classes are generated: vowels, stops, fricatives, etc.; what the acoustic correlates of phonemes are for ; what theories guide speech perception research; what feature detectors are; how researchers study infant speech perception; how locus equations de-mystify the non-invariance dilemma in stop consonant perception.

Course Requirements: (a) The textbook book for the class is the course packet, available at UT Co-op (b) Attendance will not be formally taken, but is highly encouraged to maximize success in this difficult class. (c) Makeups will be arranged for missed exams due to either sickness, religious holidays, or family emergencies. Timely arrangement is a must. (d) There is no final exam; +/- grades will be assigned [see Student Evaluation section for grading procedure]

Grading There will be four objective short answer type exams. Each = 100 points. Final letter grade will be assigned according to cumulative total as follows: Plus/minus grades will be assigned to these accumulative totals

A = 360 to 400 B+ = 340 – 349 C+= 301-309 D = 240-269 A- = 350 - 359 B = 320 - 339 C = 280-300 F = < 240 B- = 310 - 319 C- = 270-279

Pass/Fail grades: need a D to receive credit (minimum = 240 points )

The TA will conduct a review session prior to each exam
