Acoustic Prominence and Reference Accessibility in Language Production
نویسندگان
چکیده
Two experiments explored discourse and communicative factors that contribute to the perceived prominence of a word in an utterance, and how that prominence is realized acoustically. In Experiment 1 two hypotheses were tested: (1) acoustic prominence is a product of the given-new status of a word and (2) acoustic prominence depends on the degree to which a referent is accessible, where greater acoustic prominence is used for less accessible entities. In a referential communication task, speakers used acoustic prominence to indicate referent accessibility change, independent of givennew status. In Experiment 2 a variant of Tic Tac Toe was used to investigate whether effects of accessibility are driven by a need to signal the importance of a word or to indicate the word’s predictability. The results indicate that both importance and predictability contribute to the prominence of a word, but in different ways.

Acoustic Analysis of Persian EFL Learners' Pronunciation of English Vowels
This paper reports the results of an experimental study on non-native production of English vowels. Two groups of Persian EFL learners varying in language proficiency were tested on their ability to produce the nine plain vowels of American English. Vowel production accuracy was assessed by means of acoustic measurements. Ladefoged and Maddison’s (1996) F1 F2 measurements for American English v...

This study explores prosodic strengthening in the production of fortis plosives in Italian as a function of four structural levels of prominence, reflecting differing focal conditions (in order of increasing prominence: postfocal, broad focus, narrow focus and contrastive narrow focus). The overall analysis indicated that for lingual consonants closure duration was the most important acoustic p...
متن کاملTic Tac Toe: effects of predictability and importance on acoustic prominence in language production.
Importance and predictability each have been argued to contribute to acoustic prominence. To investigate whether these factors are independent or two aspects of the same phenomenon, naïve participants played a verbal variant of Tic Tac Toe. Both importance and predictability contributed independently to the acoustic prominence of a word, but in different ways. Predictable game moves were shorte...

Running head: PROSODIC PROMINENCE AND SPEAKERS’ RECALL Reduction in Prosodic Prominence Predicts Speakers’ Recall: Implications for Theories of Prosody
Repeated words are often reduced in prosodic prominence, but the underlying mechanisms remain unclear. The present study contrasted two theories: does prosodic reduction reflect the choice of a particular linguistic form, or does ease of retrieval within the language production system lead to facilitated, less prominent productions? One test of facilitation-based theories is suggested by findin...
