Course Title:               PHYSICS OF SOUND AND VOICE PRODUCTION

Course Number:                     RHS 377

Credit hours:               2+2 = 4

Prerequisite:               RHS 247

 

Course in-charge:       Dr. Ravi S Shukla

 

 

Course Description:  An examination of the basic fundamentals, concepts and theories of acoustics of speech and signal processing.  The application of scientific technique methodologies and instrumentation used in quantification, recognition and identification of speech and other acoustic phenomena

 

 

Course Objectives:

 

1.      To develop an understanding of the laws and principles that governs the transmission of sound waves.

2.      To develop an understanding of the acoustic properties of voice and speech sounds.

3.      To familiarize with the procedures and instruments used in the analysis of speech sounds

 

 

SYLLABUS:

 

WEEK 1 and 2: Introduction to sound, speech, acoustics of speech, and physical quantities like force, energy, velocity acceleration, inertia; properties of sound and ultrasonic sounds

 

 

Week 3:  Production and propagation of sound, pure tones, simple harmonic motion (SHM) with pendulum analogy, concept of waveform, amplitude, wavelength, velocity, echo, reverberations, beat frequency, decibels, equal loudness contours and free and forced vibration with pure tones and types of wave motion

Week4 and 5: Complex tones: periodic and aperiodic sounds, concept of harmonics, and spectrum of sound, free and forced vibration with complex tones. Introduction to the concept of resonance

 

Week 6: INCOURSE EXAMINATION 1

 

Week 7 and 8:  Speech mechanism as sound generator: Review of the anatomy and physiology of respiratory mechanism.  Respiratory mechanism for voice production, and understanding the following terminologies; vital capacity, total lung volume, tidal volume, residual volume, inspiratory reserve volume and expiratory reserve volume

 

 

Week 9 and 10: Review of anatomy of the phonatory mechanism; theories of voice production, introduction to the following concepts; fundamental frequency, habitual frequency, frequency Range, speaking fundamental frequency & range, semitones and the quality of voice 

 

 

Week 11: INCOURSE EXAMINATION 2

 

 

Week 12: Mechanisms involved in frequency and intensity changing process and the relationship between frequency and Pitch, and intensity and loudness. 

 

 

Week 13: Vocal tract as resonator and the acoustic properties of the vocal tract, theoretical background of format frequencies.   

 

 

Week 14:  Spectrograph and types of spectrograms, acoustic characteristic of vowels and consonant sounds

 

 

Week 15and 16: FINAL EXAMINATION:

 

 

Practical:  Practical aspects of the course include familiarizing the students with the instruments like, Vocal II, Computerized speech Lab, spirometer, Spectrograph etc and the methods of measuring various voice and speech parameters mentioned above using these instruments.
