Bias Mitigation in Audio-Enabled LLMs through Adversarial Training and Distillation Methods

Adnan Al Ali, Jindřich Libovický, Anne Lauscher

Audio-enabled large language models (AuLLMs) allow users to interact with them simply by talking to them, without the need for an intermediate transcription. This expands the model…
