LingVarBench: Benchmarking LLMs on Entity Recognitions and Linguistic Verbalization Patterns in Phone-Call Transcripts (2026.eacl-industry)
Copied to clipboard
| Challenge: | Existing methods degrade under disfluencies, interruptions, and speaker overlap, yet large real-call corpora are rarely shareable. |
| Approach: | They propose a benchmark and semantic synthetic data generation pipeline that generates linguistically varied training data via (1) LLM-sampled entity values, (2) curated linguistic verbalization patterns covering diverse disfluencies and entity-specific readout styles, and (3) a value–transcript consistency filter. |
| Outcome: | The proposed pipeline outperforms zero-shot baselines and matches or closely approaches human-tuned prompts on real customer transcripts. |
