Document Summary
Lin228 l ec tu r e 4: a co u s ti c p h o n e ti cs. Speech sounds can be described based on how they"re made (articulation: how they"re transcribed (transcription; written, how they can travel through the air i. e. transmitted and become heard (acoustic structure, today"s lecture) This time between when the sound is emitted before it is heard defines the acoustic structure.
