第二言語習得における躊躇現象

2011年度

研究成果概要:One of the many linguistic needs of second language learners is to learn the temporal patterns of the target langua...One of the many linguistic needs of second language learners is to learn the temporal patterns of the target language. That is, in addition to developing grammatical accuracy and broad lexical knowledge, learners must learn how and when to pause appropriately and in a native-like manner in order to fully master their second language productive skills. Hesitation phenomena --- including silent pauses, filled pauses (uh, um), repairs, repeats, lengthenings, and so on --- are a key overt feature of speech and can provide cues to a learner's mastery of the temporal patterns of a target language. Thus, a close examination of HP is useful to understand how learners develop and where they need to develop.This research project has therefore focused on the creation, annotation, and analysis of a corpus of first and second language speech called the Crosslinguistic Corpus of Hesitation Phenomena (CCHP) as part of a larger effort to understand the second language learner's developmental process. In principle, the project was performed as a pilot project in order to test the elicitation methods, annotation procedures, and overall design of the corpus in preparation for a larger scale corpus-building effort. However, even with its small-scale nature, the CCHP has yielded some interesting and novel findings.The CCHP currently consists of elicited recordings from ten native speakers of Japanese. Recordings were elicited in their native language (L1) as well as in a second language (L2), English. Participants were asked to perform parallel elicitation tasks in each language, varying from read speech to spontanous speech. Samples from these recordings were transcribed and annotated with respect to word and pause intervals and hesitation phenomena. Acoustic measurements of duration and first and second formant (F1,F2) values of filled pauses were also taken. Finally, native English speakers (experienced English as a foreign language teachers) rated the English speech samples for degree of native/nonnative accent and fluency.Analysis of the corpus data shows that the corpus is largely consistent with previous research of a similar nature. Results show that several features correlate well with second language proficiency. These are described one by one in greater detail in the following paragraphs.Speech rate refers to the number of tokens (i.e., words) per minute. Previous research shows that as higher level L2 speakers have a higher speech rate in their L2. The results from the CCHP are consistent with this, yet suggest that this is only part of the story: Higher level L2 speakers also have a higher speech rate in their L1. This result further suggests that speech rate ― taken by many as an indicator of L2 proficiency ― is not, in fact, a reliable indicator. Or, if it is, it is a predictor in a more determinative sense: people who naturally speak faster are more likely to achieve a higher L2 proficiency level.Token duration refers to the time duration of speakers' utterance of individual tokens in the corpus. The mean token duration shows a pattern that is consistent with previous work: Higher proficiency L2 speakers have a shorter mean token duration that lower proficiency L2 speakers. Furthermore, results show that the mean token duration does not vary when speaking in L1. Thus, unlike speech rate above, token duration can be seen as a reliable indicator of L2 proficiency., as distinct from L1 performance characteristics.Silent pause rate refers to the number of silent pauses which occur per 100 tokens. In previous research, silent pause rate has been observed to correlate well with L2 proficiency: Higher-level L2 speakers have a lower silent pause rate than lower-level speakers. The corpus in the present project confirms this result, and further shows that it is independent of L1 performance characteristics.Silent pause duration refers to the time duration of individual silent pauses. The corpus results are consistent with previous research showing that higher-level L2 speakers have a shorter mean silent pause duration, but the results further suggest that this not independent of L1 performance characteristics. That is, just like for speech rate above, results suggest that those who pause shorter in L1 are also those who pause shorter in L2.Filled pause rate refers to number of filled pauses ('uh'/'um' in English, 'e-(to)'/'ano'/'n' in Japanese) per 100 tokens. The results of the corpus are consistent with most previous research showing no difference in mean filled pause rate across L1 or L2. Filled pause rate is not a reliable indicator of L2 proficiency at all.Filled pause duration refers to the time duration of filled pauses. Previous work has not looked at this feature of speech closely. In the current project, results show that higher-level L2 speakers use shorter filled pauses than lower-level speakers. Furthermore, this trend is independent of L1 speaker performance characteristics. Hence, the results pattern like those of token duration and silent pause rate, above.Formant measurements of the filled pause vowels showed that low-level learners have an L2 vowel height that is close to the typical L1 vowel (/E/) and that as L2 proficiency gets higher, the L2 vowel height gets lower and closer to that of the typical L2 vowel (/@/). However, this same trend was also observed in L1, suggesting a backward influence of L2 filled pause vowels on L1 filled pause production. In contrast, vowel backness did not show the same trend: Higher-level L2 speakers use a more centralized vowel than lower-level speakers ― more back than the typical L1 vowel. Thus, filled pause vowel backness is a better predictor of L2 proficiency than vowel height. These results parallel other results from the corpus that relate speakers' production to accent ratings. Speakers who consistently lowered their vowels were judged more native-like (i.e., closer to L2 target pronunciation) than those who consistently backed their vowels.Repair rate refers to the number of repairs (repeats and self-corrections) that occur per 100 tokens. The corpus results here show merely that speakers have a higher repair rate when speaking in their L2 than in their L1. This is consistent across L2 proficiency levels.Repair duration refers the the length in tokens of repair sequences. Similar to the results for repair rate, speakers use longer repair sequences in their L2 than in their L1. However, this is consistent across L2 proficiency levels.These various findings are consistent with previous work showing the validity of the CCHP and the method used to obtain and annotate it. Furthermore, the findings that speech rate and silent pause duration are not strong predictors of L2 proficiency, as well as the findings that filled pause duration and filled pause vowel height are predictors of L2 proficiency are novel findings that have implications for how such things as fluency and accent are measured.

The application, called Word Quiz Creator (WQC), is a Java application that takes selected sublists of the Academic Word List (Coxhead 2000) and creates multiple-choice fill-in-the-blank quiz items by drawing sample sentences from on-line and off-line corpora.In a useability experiment, items created by WQC were compared to items created manually by an experienced test creator. The items were evaluated by experienced teachers as well as tested on student volunteers in an experimental setting.  Results showed generally that WQC created items that were nearly on a par with the manually-produced items.A description of WQC and the results of these useability experiments were reported at two different conferences during the summer of 2014. Valuable feedback was obtained from other researchers on how to improve the performance of WQC and several teacher practitioners (particularly those working at institutes with large-scale language programs) expressed an interest in downloading the application for their own use. A distribution version of WQC for download and use by researchers and teachers is now in preparation.

Providing automatic realtime feedback on temporal parameters of speech for second language fluency development

研究成果概要:This research project focused on the development and user testing of a computer application called Fluidity which i...This research project focused on the development and user testing of a computer application called Fluidity which is designed to help second language learners develop their speed fluency by giving real-time feedback on fluency-related features of speechin a manner that resembles human-human communication.At first, several speech researchers in Lisbon, Portugal who are experts in second language fluency and digital signal processing were consulted. Their advice included detailed recommendations about application design and audio libraries for signal processing.Thereafter, Fluidity was completely reprogrammed. Two main practice functions were implemented: scripted speech and free speech practice. Also, a virtual character named Fludie was added, which gives feedback to the learner via facial expressions. Also implemented were different visualizations of the learner's speech for review purposes.Finally, Fluidity underwent user testing by a number of second language learners in Portugal, France, and the United States. Afterward, each user completed a survey about their experience. Responses to Fluidity were very positive, with many users saying they would likely use it for their own language learning purposes.The new version of Fluidity and results of user testing were presented to various professional audiences in Portugal, France, Germany, Belgium, and the United States, who gave expert suggestions for further development. It is anticipated that an alpha version of the application will be released during AY2018.

The production and perception of hesitation phenomena in native spoken and written English

2015年度

研究成果概要:Many if not most language perception phenomena have listening and reading correlates in psycholinguistic experiment...Many if not most language perception phenomena have listening and reading correlates in psycholinguistic experimentation. In the perception of filled pauses (e.g., uh/um in English, e-to/ano in Japanese), experimental work has thus far looked only at filled pauses in speech showing that hearers process incoming speech differently when there are filled pauses. The present research therefore was a pilot experiment which sought to examine whether analogous results could be obtained in reading.The experiment used a self-paced reading task design with three syntactic configurations: subordinate clauses, coordinate clauses, and nouns of high contextual probability. The sentences were presented on scren in either a disfluent (with a filled pause) or fluent condition. The prediction was that the disfluent condition should generate processing difficulty and hence longer reading times.Results (N=22 native English speakers) showed that longer reading times were obtained in the disfluent condition in the region of interest (immediately after the filled pause). The results do not quite reach statistical significance, however, using mixed-effects modeling with fluency as a fixed effect and users and stimuli as random effects.  Future work will seek to increase the number of participants to that comparable to other studies of similar design.

Readers' inferences from filled pauses in written texts

They interpreted this as evidence of a structural signalling effect of filled pauses.(1) [While [the man hunted] the uh uh deer ran into the woods].(2) [While [the man hunted] the deer uh uh ran into the woods].With the rapid rise of social media, filled pauses are being increasingly observed even in print material like blogs and messaging. Therefore, it is an open question whether printed filled pauses may have comparable effects on readers. The present work seeks to examine whether the structural signalling effect extends to the reading of written stimuli. Similar to the previous work, readers judged sentences like (2) as ungrammatical more often. Furthermore, in a self-paced reading paradigm, participants’ reading times were slower in the first three regions (words) after a printed disfluency in a nonboundary location. This suggests the effect is robust across perceptual paradigms.This research was conducted via Amazon Mechanical Turk and the results were reported at the CUNY 2019 Human Sentence Processing Conference.

Modeling speech fluency for open-source e-learning application development

This year’s efforts were focused on two main goals:  first, continued development and validation of a speaking practice application called Fluidity that embodies such a model; and second, the organization of an exchange of ideas regarding fluency modeling for theoretical and practical purposes. On the first goal, the Fluidity application detection mechanisms were subjected to some acoustic validation tests to gauge how accurately the speech, pause, and syllable detection mechanisms work. The results of these tests were quite positive, showing that Fluidity performs better than a widely-used script based on the Praat acoustic phonetics analysis tool. These results are to be published in the proceedings of the annual Speech Prosody conference. On the second goal, informal discussions with the research collaborators generated interesting ideas about fluency modeling including a debate about how to make such modeling useful to such diverse fields as pedagogy and engineering. Unfortunately, a plan to host a public meeting to discuss these topics could not be carried out due to the COVID-19 situation.
