Recap Semester 1 2022/2023

Uncategorised, ,

Since September 2022, our research group has been conversing in rich discussion about various research projects occurring both within and outside our P&P team. Recent talks and presentations which have been discussed this semester include:

  • SLS Seminar- Leveraging the Adaptable Speech Perception System for Dysarthria Remediation (Stephanie Borrie):
    Carol-Ann McConnellogue gave a run through of Stephanie Borrie’s seminar for those members who could not make her presentation. Her work stresses the importance of taking the focus off speakers with speech disorders impacting their intelligibility and encouraging listeners to take more responsibility in communication. Stephanie found that listeners increased their perceptive skills of disordered speech through listening, transcribing, and imitating the disordered speech.
  • Working Memory and Speech Perception (Kai Alter):
    Kai presented a study about working memory and lexical access. The study stressed the importance of memory capacity as (a) it correlates with language comprehension in children and geriatric populations; (b) it relates to performance on school achievement tasks; and (c) it offers opportunities for intervention in SLI and DLD, with the causes of DLD still under debate. This study used high-frequency, mono-syllabic concrete nouns recorded and presented at different paces to test participants’ maximal number of items to be recalled. Unlike previous research, it found that the medical number of memory capacity was 4 instead of 7 plus or minus 2.
  • Retainability and Sustainability of Phonetic Discrimination Ability of an English Vowel Contrast by German infants (Hiromasa Kotera):
    Hiromasa presented his preliminary PhD research to the group. More information on his presentation can be found HERE.
  • Tianjin Mandarin Prosody (Cong Zhang):
    Cong came to the group with some questions and ideas regarding a presentation she planned to present at talks in Cambridge and Edinburgh. Topics she brought to the group included: (a) Is there intonation in Chinese?; (b) tone systems of Standard Mandarin vs. Tianjin Mandarin; (c) floating boundary tone; (d) functional Principal Component analysis (fPCA); (e) chanted call tune in Tianjin Mandarin; and (f) how she can turn data from recorded TV shows into a scientific study. The group provided Cong with feedback and advice.
  • Nonword Learning Project (Rory Turnbull):
    Rory presented his nonword learning project to the group so that he could receive general feedback on the overall idea, specific feedback on the pilot methodology, and recommendations of any literature and related topics. His main question posed to the group focused on why languages are the way they are, with a secondary idea questioning what are the things that influence language structure. More information on his presentation can be found HERE.
  • Correlates of Stress in Palestinian Arabic (Niamh Kelly):
    Niamh discussed her study which is investigating the main indicators of lexical stress in Palestinian Arabic through acoustical analysis. After her presentation she opened the floor to members of the group for feedback and ideas on how to improve her methodology and analysis. More information on his presentation can be found HERE.
  • Pathological Speech Analysis (Shufei Duan):
    Shufei is a visiting scholar of scalable group. She is currently Associate Professor in Taiyuan University of Technology in China, Shanxi Province. Shufei spoke to us about her project focusing on the classification of imbalanced data of Chinese dysarthria based on affective articulation. The project forms an emotional Chinese pronunciation dataset and an emotional pathological speech dataset and conducts research on the data processing of affective articulatory movement for Chinese dysarthria. Her aim is to develop an AI-assisted medical treatment and diagnosis so that diagnoses can be made remotely. Shufei’s work was of great interest to many group members and gave rise to several question-and-answer sessions. She has since attended some of our sessions, alongside her host Elly, in Semester 2 to learn about the research occurring within our group.

A new subgroup with the lovely name PIG (Prosody Interest Group) has been set up this year for our members who have an interest in prosody and intonation. This group will involve practice talks, feedback on research ideas, and discussion of relevant papers.

Some members of our group have submitted abstracts to the International Congress of Phonetic Sciences (ICPhS). We wish them the best of luck in their submissions.  

We would also like to welcome three new members to our research group: Dr Cong Zhang, Niamh Kelly, and Hajar Moussa.

Recap Semester 2 2021/2022

Uncategorised, , , , ,

From January 2022 to May 2022, our research group has continued to be well-engaged in projects from Semester 1 and arranged new workshops to discuss topics of interest amongst our team members. The following is a summary of what we covered this semester:

  • Accent and Social Justice

Since the beginning of this academic year, we have focused on the theme ‘Accent and Social Justice’, reviewed several related articles, and had Melissa Baese-Berk from the University of Oregon share her and her colleagues’ recent research with us. We organised and held an interdisciplinary workshop on accent, communication, and social justice in March of this Semester which was very successful. We were honoured to have presenters from both within our research group and outside of the group share their research and opinions. More information can be found in this blog post.

  • Many Speech Analyses

One of our main discussion topics of Semester 2 has been the Many Speech Analyses project we signed up for at the end of last semester. This project aims to compare what approaches different researchers take to answer the same research question using the same dataset. The general research question is: ‘Do speakers phonetically modulate utterances to signal atypical word combinations?’. We scheduled fortnightly meetings for this project. We started by reviewing other studies to help us plan a suitable analysis and decided to measure the timing of utterances to answer the research question. We imported the sound files to the MFA (Montreal Forced Aligner) for the forced alignment, and the results were distributed to the members for the crossed hand-correcting. Rory Turnbull, our project leader who is also a member of the P&P research group, guided us in extracting the timing of articulation of certain vowels. After analysing the dataset and submitting our report, we took a few weeks to review the reports from other researchers/research groups. Some peer analyses involved certain research methods or related tools unfamiliar to us, allowing us to expand our knowledge outside our expertise. These included:

  • Forced alignment and inter-rater reliability in Praat

During a couple of weekly meetings, we had Caitlin Halfacre and Rory run Forced alignment in the Montreal Forced Aligner and demonstrate how to hand-correct it in Praat, such as tier setting, labelling and calibration of the initial phone etc. Group members teamed up separately to help each other and shoot problems together. Bruce Wang coded in Praat to sample and measure the agreement of each text grid from the crossed hand-correct. The inter-rater reliability of our group members turned out to be quite strong.

  • Praat Phonetic Analysis 

After checking the correctness and reliability of phone alignment, Rory led two sessions demonstrating how to extract specific labels and measure the timing of utterances by coding in Praat.

  • Digital Signal Processing (DSP)

When we reviewed other researchers’ reports, we found certain research methods which were unfamiliar to us, such as DSP. We used a session as an introduction to these techniques. During this session, we watched a video to recap the anatomy of sound perception, discussed the anatomy of the cochlea, and talked about the acoustic versus auditory differences between two tones that are 100 Hz apart and gammatone filter back. However, without a well-established background in neurolinguistics, it’s still difficult for us to fully understand what the results of one peer reviewed report meant.

To conclude, we successfully ran the ‘Accent and Social Justice’ workshop and completed the Many Speech Analyses project together this semester and learnt much research knowledge and relevant expertise from this experience. We expect to explore more exciting topics and themes in the future and keep updating and publicising our work here.

LabVanced Workshops and the Lab Tour

Uncategorised

We are excited to announce that our linguistics laboratory, which was under refurbishment last year, has been reopened. The Lab has many world-class pieces of equipment. It has two small sound-treated isolation booths and one sizeable sound-proof booth to provide an ideal experimental environment. It is also equipped with high-quality phonetic and speech recording tools, as well as ultrasound tongue imaging. The Lab can support a wide range of articulatory, phonetic, psycholinguistic, and corpus research, and you can read here for more information.

The Lab is licensed to use LabVanced, an online experimental designing and launching system. On the 19th and 25th May, Fengting Du and Andreas Krug, who are members of our research group, demonstrated how they used LabVanced to benefit their research. The questions covered were: (1) how to start up a new study; (2) how to import your stimuli; (3) how to set variables and record the data you want; (4) how to randomize the order of your questions or stimuli; and (5) how to launch your study and export your data. We also shot some problems about data analysis together during the workshops.

After the workshop, the research group had a demonstration of ultrasound tongue imaging from the Lab administrators. If you are interested in the Lab equipment and want to know more, you can call into the Lab or book the Lab here.

Please leave a comment if you have questions on LanVanced or would be interested in another training session. We look forward to arranging further workshops like this.

Accent and Social Justice Workshop

Workshops, , , , ,

Our research theme for 2021/22 has been “Accent and Social Justice”. We have read and reviewed literature on accent processing and perception, and discussed the prejudices towards certain accents and the injustices those may experience.

In order to spread awareness about accent and social justice, and the research our group has undertaken, we have organised an interdisciplinary workshop on accent, communication and social justice, which will be held on 30/03/2022.

The workshop will consist of presentations from members of our research group and academics outside of the field of Phonetics and Phonology who have an interest and knowledge in our research theme. Topics which will be discussed include self-descriptions of UK-based English accents; constructing native speakerism in Chinese community schooling; and racist nativism in England’s education policy, to name a few. The abstracts for each presentation can be found here. There will be time for discussion after each presentation to give attendees the chance to ask questions, exchange ideas, and explore the topics further.

The workshop will begin at 9am on Wednesday 30th March. It will be a hybrid event meaning people can attend in person or via Zoom. For those attending in person, the workshop will be held in room G.21/22 of the Devonshire Building at Newcastle University. Lunch will begin at 12pm and refreshments will be provided. This will be another opportunity for attendees to mingle and discuss the topics explored. The workshop will end at 1pm. The full workshop programme can be viewed here.

If you are interested in attending our workshop, you can sign up using this link.

We look forward to seeing you and hope this workshop enables you to delve into rich discussion around a very important issue.
