A new research paper introduces a method to pinpoint why audio-language models (audio-LLMs) fail to utilize prosodic information, which conveys emotional and linguistic nuances beyond just the words spoken. The study proposes a stage-specific probe ladder to identify whether the failure lies in acoustic information loss, incorrect internal interpretation, or a lack of expression from an available internal representation. Experiments on four audio-LLMs revealed that while prosodic information is generally preserved and decodable in late model states, it is not fully expressed in the final output, indicating a bottleneck in the model's ability to use this information rather than perceive it.
