Document Summary
Acoustic phonetics: physical properties of speech sounds (not covered in this course) Auditory phonetics: how sounds are heard and perceived (not covered in this course) Identify the beginning sound of ban" as the same as the beginning sound of bun" brick", etc. Identify the ending sound of ban as the same as the ending sound of ton, thin, etc. We know that as a rule because we are. Acoustic signals do not come with segment boundaries. You cannot really isolate b" from a" or n" from a" in the continuous acoustic signal. The articulatory gestures for different segments are typically produced with a significant amount of overlap. While your mouth is closed for b your tongue is already in position for a. In other words english speakers hear segments when they are not necessarily evident in the physical signal. Listeners hear segments, but they ignore things that are not useful to them.
