Researchers have introduced Grounded Generative Speech Recognition (GSR), a new framework that moves beyond traditional transcription to evaluate speech-to-text systems. GSR reformulates speech recognition as generating semantically grounded text, acknowledging that multiple valid textual outputs can correspond to a single utterance. The proposed GSR-Bench benchmark evaluates these systems across various capabilities, including literal transcription, canonical reformulation, semantic reformulation, and speech-grounded structuring. A novel multi-dimensional evaluation framework, combining speech grounding assessment and LLM-based semantic judgment, has been developed to address the limitations of word-level metrics, with its reliability validated by human studies.
