Speech and Segments
Native speakers of English can:
-identify the beginning sound of ban as the same as the beginning sound of bun brick’,
-identify the ending sound of ban as the same as the ending sound of ton, thin, etc.
- how do we know that we have speech segments? We know that as a rule because we are
English native speakers.
-evidence of segments from speech errors
-slips of the tongue/spoonerisms
-you have hissed my mystery lecture
-segments as planning units in speech production
-spelling doesnt help with segments. Were working with how out mouth moves.
We hear things that are not there.
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. Compare
with bean
