LIN228H1 Lecture Notes - Speech Recognition, Sine Wave, Sound
Document Summary
The way we have described speech sounds so far was in terms of how they are produced by manipulating the vocal apparatus and how they can be transcribed with phonetic symbols on paper. However, we can also describe sounds in terms of how we can hear them. How we can hear a sound depends on its acoustic structure. Acoustic phonetics: the science of the physical properties of sounds. the science of the physical properties of speech sounds. A line of people waiting to buy tickets to a concert is useful analogy for a sound wave (based on. The movement of the person at the front of the line creates a gap ( rarefaction"); this gap travels through the line. Then the first person is shoved back into the second person, creating more crowdedness ( compression"); the crowdedness also travels through the line. Wave motion in a line of seven people (1-7), from time 1 to time 15 in arbitrary units.
