This course is designed to introduce students to the techniques of sound processing including basic aspects of human hearing,
physics of acoustics, cognitive psychology of hearing, audio transmission quality, digital audio, and speech synthesis and
speech recognition technology.
In the first half of the lecture, participants learn analogue aspects centered on the correspondence between the physical
properties of sound and human senses. In the second half of the lecture, participants learn the basics of audio signal processing,
and then learn about coding of speech signals, speech synthesis, and speech recognition.
- Be able to explain the outline of basic concepts related to sound and sound processing engineering and the basic mechanism of sound information processing.
- Be able to explain basic technical terms related to acoustic and speech processing engineering.
- Be able to explain representative techniques and information processing methods related to digital sound processing.
