## Summary

A team of researchers tested whether small, self-hosted voice agents could adapt to new legal procedures in debt collection without retraining. They used a 9-billion-parameter model fine-tuned on 2,506 conversations from 297 randomized procedures. The agents were tested on four unseen deployment procedures—three debt-related and one unrelated—including one from a completely withheld lineage.

The study found that compliance checks improved from 67–71% to 93–100% after training, while grounded checks (fixed by conversation) already passed at 97–100%. Scenario pass rates rose from 15/43 to 40/43. An audit of the shared specification uncovered 11 defects, three of which the model’s own metrics missed.

## Key points

- Researchers fine-tuned a 9-billion-parameter model on 2,506 debt-collection conversations from 297 procedures
- Compliance checks improved from 67–71% to 93–100% on unseen procedures after training
- An audit found 11 defects in the shared specification, three of which the model’s metrics missed

## Why it matters

If voice agents can generalize to unseen legal procedures without retraining, it could reduce compliance risks and costs for regulated industries like debt collection.
