Part Five: Ch 23.3~6 How do Listeners Compensate for Phonology?
23.3 Experiment 2
23.3.1 Methods
Use monomorphemic non-words in (C)VCCV(V)
A linguistically naïve female native Korean speaker recorded the stimuli
310 different items occurred twice
Ten Korean native speakers as listeners
23.3.2. Results
Listeners show high rates of correct response(96.8%) to the fillers.
23.3.3 Discussion
Goal
Whether listeners can infer the underlying forms
From phonetic homorganic clusters in non-words
Interesting result
Velar stimuli
Both /s.k/ and /p.k/ assimilate to [k.k] in natural speech
Main factors of lowering YES response
Frequency of labial-to-velar assimilation
Coronal-to-noncornoal assimilation
23.4 Experiment 3
23.4.1 Methods
Stimuli is pseudo-compounds consisting of two words
Listeners were provided transcription options
Ten Korean native speakers
23.4.2. Results
Rate of YES is 96.3%
Subject understood the task
23.4.3 Discussion
Purpose
Test the expectation
If listeners identified the initial morpheme in a new compound
Response
Higher than the previous ones
23.5 General Discussion
Subject are
preferred homorganic clusters as underlying forms
preferred coronal as targets of assimilation
Response pattern in Experiment 2 &3
Support the phonological-inference account
Listeners did not recover legal heterorganic clusters as underlying form
Result of Experiment 3
Show listeners reply more on phonological inference.
23.6 Conclusion
Goal
To test whether listeners use their phonological knowledge to infer original forms in speech recognition
Result suggest
Phonological inference is a part of the speech recognition process
