PED: Route-Decoupled Diagnostics for Persona Consistency in Spoken Agents (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing evaluations of persona-emotion decoupling frameworks do not isolate which component caused the failure . current evaluations do little to isolate the cause of the failure, making fixes slow and ad hoc . |
| Approach: | They propose a diagnostic evaluation framework that decomposes persona expression into two observable routes. |
| Outcome: | The proposed framework decomposes persona expression into two observable routes . it can be used to perform route-comparable, reference-based analyses of separability, drift, failures and coupling . |
