New APEX framework boosts spoken language understanding accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel two-stage retrieval framework called APEX for spoken language understanding (SLU) that improves upon standard query-based methods. This framework first identifies potential intents using intent-level prototypes and then retrieves relevant contextual examples within those identified intent spaces. Experiments on the SLURP dataset demonstrated that APEX, when used with Qwen3-4B and Gemma-3-4B models, significantly boosted Exact Match Accuracy (EMA) by up to 7.66 percentage points, particularly under challenging high-perplexity input conditions. AI

IMPACT This research offers a more robust method for intent detection in spoken language, potentially improving the accuracy of voice assistants and other SLU systems.

    An Effective Spoken Language Understanding Approach Leveraging Query-Adaptive Intent Detection

    arXiv:2611.09491v1 Announce Type: new Abstract: Large language models enable fine-tuning-free spoken language understanding (SLU) through in-context learning, but direct query-based retrieval may select semantically similar yet intent irrelevant demonstrations. This paper present…
