- Dr Williams conducts research in audio processing as it is applied to smart cities and smart buildings. She investigates connections between audio AI services in smart buildings that can detect and analyse occupant presence, movement, and activity levels and incorporating this information into reinforcement learning algorithms to simultaneously optimise resource consumption (energy, ventilation, cost, etc) with occupant preferences and comforts.
- Along these lines, her research also addresses issues of audio AI safety in terms of usability, privacy, and security. These issues overlap with procesing in edge devices (e.g., ultra low-power devices and chips via TinyML). Her work addresses ethical issues of trust for audio AI, spanning a breadth of topics such as: deepfake detection, voice as a form of property, and speaker and content privacy.
