Project Overview¶
CHAIS: Crossmodal Human-AI Collaboration for Selective Hearing Assistance
[!note] Project Proposal CHAIS.pdf
The CHAIS project is about developing bio-inspired crossmodal Speech Enhancement algorithms to address the Cocktail Party Problem. This should be showcased in prototypical smart Glasses that support humans during selective hearing tasks. The speech enhancement should utilize mechanisms informed by cognitive speech processing in humans to (1) potentially improve real-time speech enhancement and (2) gain further insights into how these mechanisms improve speech comprehension.
The project is a cooperation between three Project Partners:
| Partner | Focus |
|---|---|
| Human-Computer Interaction | Develop human-usable assistive glasses, based on user needs and feedback. |
| Signal Processing | Improve AI-based real-time speech enhancement for hearing assistance in humans. |
| Neuronal Information Processing & Computational Neuroscience | Apply and gain insights into cognitive mechanisms in speech processing. |
