Abstract
-
This study investigated the role of sentence context on the perception and production of internal open juncture. Three experiments were performed. The first was designed to determine whether there are differences in intelligibility between internal open juncture phrase pairs produced in isolation and produced in context but heard in isolation. Phrases spoken and heard in isolation are easy to identify. These phrases spoken in a sentence and presented in isolation cause difficulty for the listeners. The acoustic characteristics in both conditions are largely the same.;Experiment II investigated the effect of sentence context on the perception of internal open juncture. It employed grammatically and semantically anomalous sentences to demonstrate the role of context. When the context is varied such that the phrases are anomalous in certain sentences, the listener uses contextual cues although the acoustic cues are present. When context was correct, almost no listening errors occurred. When context was present but provided no information as to which phrase was spoken, the listener made a considerable number of errors.;The third experiment examined specific hypotheses developed from the results of the first two experiments, regarding the relative importance of contextual and acoustic cues in the perception of internal open juncture. Phrases in anomalous context and in correct context were used. In addition, the same phrases excised from the sentences were presented to the listeners for identification. The anomalous context situation caused considerable listening errors. The excised phrases also caused listeners some degree of difficulty. When the phrases were in anomalous contexts the only factor that affected the responses (in terms of juncture decision) was how anomalous the context was. In the isolated condition phrases with the consonant before the juncture were more difficult than those with the consonant after the juncture. Phrases with the stop consonants /d/ and/t/ were easier to identify than those with the consonants /m/ and /s/.;It was concluded that for internal open juncture, acoustic information serves to delimit the choice to one of two possibilities and the context is used in making the final decision as to which phrase the speaker intended.
