  • Crosslinguistic Corpus of Hesitation Phenomena: A corpus for investigating first and second language speech performance

    14TH Annual Conference of the International Speech Communication Association (INTERSPEECH 2013)     991 - 995  2013  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    There is a growing consensus that there is a need to evaluate second language speech performance with respect to first language speech behavior. To support this need, the Crosslinguistic Corpus of Hesitation Phenomena was developed. This freely available corpus is designed to investigate the crosslinguistic influence of speech patterns and consists of recordings of speakers producing first and second language speech samples in response to parallel elicitation tasks in each language. Preliminary results from the corpus are consistent with other findings that second language performance is sometimes correlated with first language speech behavior. In particular, findings show that silent pause rate and duration as well as other hesitation phenomena correlate with first language performance while speech rate does not. Interestingly, repeats also differ from first language production. Results show that the corpus may be a useful tool for researchers who wish to investigate the correspondence between first and second language speech, particularly with respect to the use of hesitation phenomena.

    INTED2016: 10TH International Technology, Education and Development Conference     8032 - 8040  2016.03  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Word Quiz Constructor is a java application designed to automatically generate vocabulary quiz questions based on corpora. Past work has shown that it generates multiple-choice cloze items using sentences from Wikipedia that are comparable to manually-produced items, but the context sentences tend to be longer and more difficult. The present study describes an evaluation of Simple English Wikipedia as an alternative source for quiz items generated by Word Quiz Constructor. Results show that items generated are shorter and at a lower reading level than those from regular English Wikipedia. But a validation test with native English speakers via Amazon Mechanical Turk suggests that Simple English items with a higher reading level have a somewhat diminished quality. Simple English Wikipedia seems optimal for the generation of low reading level items only. Suggestions are made for the future development of Word Quiz Constructor with Simple English Wikipedia.

    2010 IEEE International Professional Communication Conference     138 - 142  2010.07  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    This paper describes a course in pronunciation for science and engineering students studying English as a foreign language in Japan. The course is designed to address the pronunciation needs of science and engineering students while simultaneously catering to the sensory, visual, and active learning styles of these students as well as their interest in and higher aptitude for math, physics, and technology. Students are introduced to the sound system of English and use computer-based tools to look at graphic representations of their own voice, comparing it to those of native speakers. Students learn how to diagnose their own pronunciation problems and develop skills so that they may continue their pronunciation development long after the course is finished through autonomous learning.

    Authorship:Lead author, Corresponding author

     View Summary

    Beginning with the observation that syntactic and semantic information often coincide (i.e., subjects are often agents, objects often patients), this study investigates the possibility that preference to resolve a sentence-initial pronoun to a syntactically prominent antecedent might actually be better explained in terms of preference for resolving to a semantically prominent antecedent. The study takes Discourse Prominence Theory (Gordon and Hendrick [11,12]) as an underlying framework. Results of three psycholinguistic experiments using a self-paced reading task show that both syntactic and semantic information guide readers' pronoun resolution preferences. This suggests a revised understanding of Discourse Prominence Theory in which the prominence of discourse referents is determined through a complex process depending on multiple linguistic factors. Results further show that the relative degree of prominence among competing candidates influences resolution processes.

     View Summary

    The crosslinguistic study of speech phenomena is very common and often involves investigating native speakers of various languages to discover similarities and differences between their respective languages. When studying second language speech production, a native speaker group may be included as a reference. But much less often is native speech from second language speakers also gathered to provide a baseline (cf., Segalowitz 2010). In this talk, I will present data from a series of studies based on such a crosslinguistic corpus, containing first and second language speech samples from each participant. In particular, I will focus on the pausing patterns of these speakers to show how they use silent pause and filled pauses (e.g., ‘uh’/’um’) in their second language speech, and how we may better interpret this use in light of their first language speech behavior. Finally, I will discuss and demonstrate some practical approaches to the development of their L2 proficiency based on the findings.

    Psycholinguistic research shows that in a text, focus of attention shifts and unnatural pronoun use require greater cognitive effort for readers/listeners to process. The presenter will extend the Gricean (1975) concept of cooperation with such psycholinguistic evidence to outline a compact model of how speakers/writers cooperatively maintain the focus of attention across utterances. The presentation will conclude with suggestions for classroom activities designed to raise learners' awareness of these features of discourse competence.

Specific Research

  • Constructing a corpus for the study of simulated filled pauses

    2021  

     View Summary

    When actors and voice artists speak within the context of a dramatic presentation, they may use disfluencies to make their speech sound more authentically spontaneous. However, there has been little study of whether these simulated disfluencies match patterns produced during truly spontaneous (that is, unscripted and unprepared) speech. The aim of this project was to evaluate this in a mini corpus of film and television dramas, as well as in elicitation from professional voice actors. A small corpus of 10 films and television shows was assembled, comprising a total of 122 filled pauses. The relatively small number means that conclusions are tentative, but the use of filled pauses seemed to fit typical patterns of use. They were more frequent at major than minor discourse boundaries, and uh was more frequent than um. An exception was that they did not necessarily precede words of low contextual probability, as has been previously shown in spontaneous speech. Two professional voice actors were hired to re-produce two different texts in three manners: scripted speech, scripted speech with simulated disfluency, and original spontaneous paraphrase. Two voice actors made recordings and results showed that the simulated disfluency was quite different from their actual disfluency.

  • Hesitation phenomena and disfluencies in artificial speech generation

    2021  

     View Summary

    Artificial speech generation has existed for many decades and recent applications produce quite convincing results as evidenced by a number of widely known commercial applications. However, only recently have some of these applications begun to exhibit typical signs of spontaneous speech with the inclusion of disfluencies, despite the fact that these applications are most definitely NOT producing spontaneous speech. While the idea of inserting disfluencies has been tested in some ways for the past decade, there is not much controlled investigation of this trend. A corpus study was performed to look at patterns of disfluency use in a cross-linguistic manner. The experiment used the Crosslinguistic Corpus of Hesitation Phenomena (Rose, 2013) and extracted a wide variety of acoustic features of disfluencies exhibited in this speech corpus. The acoustic information was processed through a clustering algorithm to find common disfluency trends among sub-groups of the 35 speakers in the corpus. Surprisingly, the clustering method yielded a large number of groupings, suggesting that speakers are quite unique in their disfluency methods and cannot be easily categorized. One conclusion is that “mean” disfluency trends might be used in generated speech, for example as “nudges” to help learners achieve certain learning outcomes more readily.

  • Developing gold standard data for Vocabulary Training and Testing

    2021   折田 奈甫, 菅原 彩加, ワン チャオ

     View Summary

    We established three main aims during the year: to create a “gold standard” set of testing items, to develop a mock-up application for testing purposes, and to carry out a pilot investigation involving the gold standard items and the mock-up application. The gold standard items focused on creating a large number of multiple choice cloze vocabulary test items based on the General Service List and the Academic Word List. 5,000 items were generated automatically and then evaluated and corrected by experienced language teachers. In the end 2,786 items were retained in the gold standard set. Concurrently, an on-line vocabulary training and testing application was developed. Learners can choose a specific GSL or AWL sublist to focus on and receive practice items or take a short test occasionally to evaluate their knowledge of a specific sublist. Finally, a pilot experiment was carried out with 12 student participants. Over a two-week period, the participants were free to use the vocabulary application at their own pace, but with a target to study vocabulary a total of about 6 hours, spread out evenly across the time. Pre- and post-test results showed a significant gain in vocabulary knowledge over the two-week period.

  • Converting an automatic word quiz creation application into an open-source tool

    2020  

     View Summary

    Word Quiz Constructor (WQC: Rose 2014) is a Java console application designed to automatically generate vocabulary quizzes with questions testing learners’ knowledge of Academic Word List (AWL: Coxhead 2000) words. This project’s aim was to prepare the project for public distribution in two ways: (1) Develop the application for greater user customizability while evaluating its custom features to suggest optimal settings for different scenarios and (2) converting the application to a publicly distributable archive. For the development aim, WQC was further implemented with the capability to make use of different readability algorithms which are useful for controlling the difficulty level of stem sentences in cloze questions. It was also further implemented to make use of different frequency lists for checking the frequency of tri-gram sequences surrounding target words. The optimal configuration overall was found to be that using the Linsear Write readability algorithm with the British Academic Written English (BAWE) corpus frequency list and drawing carrier sentences from Simple English Wikipedia. The Coronavirus situation pressed WQC into full-time service in the English program with the creation of question banks. Results showed good discrimination ability of the questions produced. Finally, the second aim was achieved with the publication of a distributable application on the Roselab web site (author’s university web page).

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

    2019   Sheppard, Chris, Kinoshita, Naoko, Shinohara, Yasuaki, Sagisaka, Yoshiori, Kondo, Mariko, Sun, Yue

     View Summary

    This project aims to develop a shareable model of second language speech fluency that can be utilized by both language teaching practitioners as well as language learning technology engineers and programmers. 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.

  • Readers' inferences from filled pauses in written texts

    2018  

     View Summary

    In work by Bailey and Ferreira (2003), listeners who heard filled pause disfluencies (i.e., “uh uh”) at structural non-boundary locations (e.g., (2) below) judged the sentence stimuli as ungrammatical more often than when the disfluency was at (or very near to) a boundary location (e.g., (1) below). 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.

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

    2017  

     View Summary

    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  

     View Summary

    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.

  • 大規模第2言語教育用語彙認識クイズのマスプロダクション

    2014  

     View Summary

    The primary purpose of this project was to develop and report on an application which is designed to produce vocabulary tests en masse for large-scale English teaching programs. 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.

  • 第二言語習得における躊躇現象

    2011  

     View Summary

    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.
