## Why Included

DramaSR-532K benchmarks speaker attribution over 532K dialogue lines and 900+ TV-drama characters; a reasoning LLM with multimodal tool use beats acoustic baselines, especially on short utterances.

## Source Summary

**The gist** The paper ships **DramaSR-532K**, a benchmark of **532K annotated dialogue lines across 900+ characters** in long-form TV dramas, plus **DramaSR-LRM**, a reasoning LLM that calls audio, text, and visual tools to attribute each line to a speaker.

## Practical Implication

**Why it matters** It's a concrete case of the agentic pattern — reasoning model plus **multimodal tool use** — beating specialized pipelines where a single signal fails: voice biometrics collapse on **short utterances**, and cross-modal evidence aggregation recovers them. Relevant if you build media-understanding or transcription tooling.
