People are now regularly interacting with voice assistants (VAs), which are conversational agents that allow users to use spoken language to interface with a machine to complete tasks. The huge adoption and daily use of VAs by millions of people - and its increasing use for financial, healthcare, and educational applications - raises important questions about the linguistic and social factors that affect spoken language interactions with machines.
We are exploring issues of linguistic and social biases that impact speech communication in human-computer interaction - particularly during cross-language transfer, learning, or adaptation of some kind. In this talk, I will present two case studies illustrating some of our most recent work in this area. The first study looks at a case of cross-language ASR transfer. We find systematic linguistic and phonetic disparities in language transfer by machines trained on a source language to speech recognition of a novel target, low-resource language. The second study looks at a case of social bias in word learning by humans using voice-enabled apps. We find the word learning is inhibited when there are mismatching social cues presented by the voice and the linguistic information.
Together, along with highlights from other ongoing work in my lab, the aim of this talk is to underscore that human-computer linguistic communication is a rich testing ground for investigating issues in speech and language variation. Examining linguistic variation during HCI can enrich and elaborate linguistic theory, as well as present opportunities for linguists to provide insights for improving both the function and fairness of these technologies.

The rapid development of artificial intelligence and large language models have led to the language industry and translation and interpreting education programs re-imagining how to engage with these technologies. While some language industry stakeholders seek to leverage these tools to support the provision of language services and language access, others have sought to resist this technological incursion on ethical and professional grounds. The impact of these tools is undoubtedly far reaching, to the point that trainers and educators must now respond to these developments. This talk reviews some of the ways in which artificial intelligence, large language models, and translation and interpreting technologies can be leveraged in educational and training programs while offering possible means to resist uncritical adoption of these tools. The talk provides suggestions on how university programs can prepare future graduates to interface with these technologies and drive ethical and responsible technology use.

This was followed by Prof. ZHANG Chenqi, Chair Professor of Artificial Intelligence of the PolyU Department of Data Science and Artificial Intelligence, and Director of the PolyU Shenzhen Research Institute introducing the speaker.
Prof. Zhang said, “The development of large models is at the core of competition in the AI wave. DeepSeek has demonstrated that high-performance AI models can be achieved using fewer and less advanced graphics processing units (GPUs), demonstrating that cutting-edge AI technology can be realised through the optimisation of algorithms.”
The large AI model developed by the mainland Chinese startup DeepSeek has garnered wide acclaim around the world for its low-cost, high-performance, and open-source framework, disrupting the traditional “computing power-first” logic of AI model training. At the Forum, Prof. Yang highlighted the potential of generative AI (GenAI), adding that it presents abundant opportunities for various sectors, including healthcare, finance, manufacturing, retail, media and fashion, and for applications in medical imaging analysis, fraud detection, predictive maintenance, retail inventory management, content creation, and design and marketing.
Prof. Yang also recounted the evolution of AI and shared her professional milestones with the audience, notably the development of the M6 large model, which trained a 10-trillion-parameters model using just 512 GPUs. Prof. Yang further elaborated on how her GenAI project, Co-GenAI, improves the accessibility of AI technology while minimising dependence on large-scale centralised computing resources, thereby transforming the trajectory of AI progress. This ground-breaking effort has positioned Hong Kong and the Mainland at the forefront of global advancement in GenAI.
Moderated by Prof. Zhang Chenqi, a panel discussion was also held, featuring esteemed panellists Prof. Yang Hongxia and Prof. LI Qing, Head and Chair Professor of Data Science of the PolyU Department of Computing, and Co-Director of the Research Centre for Digital Transformation of Tourism.

The lecture commenced with a warm welcome and introduction of the speaker by Prof. CHEN Qingyan, Director of PAIR. Prof. McCulloch kickstarted his presentation by giving a brief overview of the current molecular designs of organic semiconductor polymers for charge transport. He explained how they enable organic thin film transistors to achieve high charge carrier mobility and their applications in flexible screens and other electronic devices. He then elaborated on the molecular characteristics of the indacenodithiophene-co-benzothiadiazole copolymer, a semiconductor polymer that exhibits high carrier mobility and is commonly used in organic transistors.
Prof. McCulloch also emphasised the importance of “conformational coplanarity” and “side chain assisted self-assembly”. These features help enhance one-dimensional transport along the “conjugated polymer backbone” and form sterically free “crossing points”, allowing charges to hop between chains. He further highlighted that current research has shown that the molecular conformation and film microstructure are influenced by the design and processing conditions of organic semiconductor polymers, and these significant findings can help achieve optimal charge transport properties.
Following the presentation was a question-and-answer session moderated by Prof. YAN Feng, Associate Director of the Research Institute for Intelligent Wearable Systems (RI-IWEAR) and Chair Professor of Organic Electronics in the Department of Applied Physics. The audience engaged in a productive discussion with Prof. McCulloch.
