Small LLM voice agent adapts to unseen debt collection procedures in study

Key points

• Researchers fine-tuned a 9-billion-parameter model on 2,506 conversations from 297 randomized procedures.
• On four unseen Thai outbound-call procedures, documented checks rose from 67-71% to 93-100%.
• Scenario pass rate reportedly improved from 15 of 43 to 40 of 43 after training.
• An audit of the shared specification found 11 defects, three of which its own metric missed.

Why it matters for marketers: Suggests compliant call scripts could be generated from one structured spec per client, with less retraining for each new regulated procedure.
