Introduction
Welcome to the "Acoustic-Phonetics Demonstration" website! This website introduces demonstrations of interdisciplinary fields related to acoustic phonetics. We have a collection of demonstrations, some of which you may have only read about in textbooks, but have never actually heard the sounds or seen the demonstrations. We have a number of speech and sound demonstrations, as well as demonstrations using graphics and videos. The number of demonstrations is expected to increase. If you have any questions, comments, or requests, please feel free to send an email to the following.
