Toward a speech neuroprosthetic​

RSVP for this talk

Abstract

Speaking is a unique and defining human behavior.  Over the past decade, we have focused on deciphering the basic neural code that underlies our ability to speak fluently.

During speech production, vocal tract movement gestures for all speech sounds are encoded by highly specialized neural activity, organized as a map, in the human speech motor cortex.   A major effort is now underway to translate these findings towards building a articulatory-based speech neuroprosthetic device for people who cannot communicate.

Dr. Edward Chang, Professor of Neurological Surgery at the University of California, San Francisco, will present this Language Science Talks event as part of the Djavad Mowafaghian Centre for Brain Health Research Neuroscience Research Colloquium series.

This talk is co-hosted by the Djavad Mowafaghian Centre for Brain Health Research and the UBC Language Sciences Initiative. We ask that attendees refrain from wearing perfumes and scented soaps to prevent causing allergic reactions for other attendees.

Learning new sound categories​

&

Visual, lexical, and clear speech contributions to speech perception

 RSVP for this talk

Abstracts

Learning new sound categories​: Language changes throughout the life span and it is well established that training has practical benefits for language learning. This talk will review some of our training studies that show that adult learners can acquire and retain new sound categories. Advantages and disadvantages of the high-variability training paradigm will also be discussed and the influence of perception training on production and production training on perception will be examined as well. In addition, the talk will present some data on how varying the nature of the distributions presented during training can also provide insight into the mechanisms of language learning. 

Visual, lexical, and clear speech contributions to speech perception: One of the primary goals of speech research is to characterize the defining properties of speech sounds that occur in natural language, and to determine how the listener extracts these properties in the process of speech perception. In this talk, several types of data will be presented to advance our understanding of the relationship between production and perception of speech. Specifically, comparisons of conversational and hyperarticulated speech serve to identify the acoustic cues that may be most important to speech communication. In addition, data from sentence processing and audio-visual experiments address the extent to which linguistic and facial information can enhance speech communication above and beyond the acoustic information. English fricatives are considered as an ideal test case: they span a wide range of places of articulation and include fricatives that have acoustically salient but visually weak cues as well as fricatives that are visually salient but acoustically weak. Results suggest that accurate perception of fricatives, especially non-sibilant fricatives, derives from a combination of acoustic, linguistic, and visual information. 

Professor and Chair of the Department of Linguistics at the University of Kansas, Joan Sereno’s work examines how converging evidence from language comprehension and production relate to specific brain processes. Her current research focuses on the training and learning of non-native language contrasts. Recent publications include “How category learning occurs in adults and children” and “The relative contribution of segments and intonation to the perception of foreign-accented speech”. Dr. Sereno is co-Director of the KU Phonetics and Psycholinguistics Lab. 

Allard Jongman is Professor and Associate Chair in the Department of Linguistics at the University of Kansas, and co-director of the KU Phonetics and Psycholinguistics Lab.  Dr. Jongman’s research focuses on acoustic phonetics and speech perception.  Recent publications include “Computer-vision analysis reveals facial movements made during Mandarin tone production align with pitch trajectories” in Speech Communication with S. Garg, G. Hamarneh, J. Sereno, and Y. Wang and “Tonal neutralization of Taiwanese checked and smooth syllables: An acoustic study” in Language and Speech with Y-F. Chien.

Temporal Aspect in American Sign Language

Abstract

In this presentation, I will discuss aspect in American Sign Language (ASL), demonstrating that ASL users have a range of options to produce aspectual meanings, including verb reduplication, aspectual verbs, adverbial signs and phrases, aspectual nouns, and combinations of the above.

How prenatal experience shapes speech perception​

Abstract

Experience with language starts in the womb. The prenatal speech signal is filtered by maternal tissues, preserving the rhythm and melody of speech, i.e. prosody, but suppressing fine details needed for the identification of individual speech sounds. The talk will examine the hypothesis that this prenatal experience with speech prosody might already shape how newborns perceive speech. In a series of NIRS and EEG experiments, I will show that basic auditory mechanisms such as envelope tracking are immune to prenatal influence, while more language-specific mechanisms, such as prosodic grouping, are already modulated at birth. I will discuss how these mechanisms lay the foundations for later language acquisition.

Storybook Mexico: Best practices to promote children's literacies in Indigenous languages​

Abstract and Bio

In this talk we discuss ideas to promote children´s literacies in the indigenous languages in Mexico. In Mexico, all indigenous languages are minority languages, some of which have several linguistic variants that are in different situations and degrees of vitality and endangerment. Today, these languages are undergoing varying processes of standardization. Also, a portion of the indigenous children learns to read and write in the native language during the first years of primary school. However, relatively few indigenous speakers have developed literacies in their mother tongue. The unequal situation and position of indigenous languages in Mexico creates a challenging situation for the support of indigenous literacies. 

Storybook Mexico is a project aimed to support Mexican indigenous and non-indigenous children, families, and communities access multimodal stories (written text, audio and images) in their ancestral languages. During the project, we collaborated with a UBC team from Language and Literacy Education to translate open access stories from the African Storybook into some of the local indigenous languages of Mexico, using the Storybooks Canada modular website (https://global-asp.github.io/storybooks-mexico/). Based on this experience, we address the development of best practices for collaborative work with the speech communities, linking the needs and interests of the (heritage) speakers themselves to the translation practice. This includes the awareness of local language ideologies towards the Indigenous languages, but also towards literacy events and literacy practices. Likewise, we stress the importance to better understand the theoretical underpinnings of cross cultural translation between Indigenous languages, taking into account the experiences, viewpoints and investment of the translators.

From text analytics to predictive analytics enhanced by language sciences

Abstract

Computer Science professor Raymond Ng will present this talk, the first half of which will give a short overview of some of the research Dr. Ng has conducted, analyzing various types of text data, including sentiment analysis and abstractive summarization. In the second half of the talk, Dr. Ng will discuss how to build predictive models based on text and data of various kinds. He will use examples involving identifying patients with emotional needs, and stratifying children with potentially high risk for suicide.  Finally, Dr. Ng will speculate as to how language sciences can enhance predictive models that are purely data-driven.

Indigenous Storybooks: Protocols and Educational Possibilities​

Abstract

Exploring Protocols in Digital Territories: Dr. Sara Florence Davidson, an Assistant Professor in Teacher Education at the University of the Fraser Valley, discussed the complexities of honouring protocols in digital spaces. Specifically, she focussed on how the Indigenous Storybooks project is being used to support community Indigenous language revitalization efforts and how the platform is being used to support educators to honour existing protocols associated with the sharing of traditional Indigenous stories in their classrooms. 

Digital Literacy in Canada and Beyond: Dr. Bonny Norton (FRSC), a Professor in UBC’s Department of Language and Literacy Education (LLED), discussed the relationship between Storybooks Canada, Indigenous Storybooks, and Global Storybooks, and introduced the team’s current collaboration with an Indigenous language project in Mexico. In March, 2019, The Province newspaper identified Storybooks Canada as one of four reading app recommendations by local librarians, noting its multilingual features and its connection with Indigenous languages. 

Digital Literacy and Indigenous languages: Liam Doherty, a PhD Candidate in UBC’s Department of Language and Literacy Education (LLED), discussed how an approach leveraging open licenses and open content can help to address some of the challenges presented by the digitization and distribution of material in Indigenous languages in a manner that is respectful of practices and protocols surrounding access. When combined with an open source development strategy such an approach can also maximize the impact and reach of digital tools for working with Indigenous languages across communities by reducing duplication of effort, improving accessibility, protecting (individual and community) privacy, guarding against platform obsolescence, and encouraging a digital culture of knowledge and resource sharing.
