What happened and what to do
On June 23, 2026, Artificial Analysis introduced an index of native Speech-to-Speech models. It combines Big Bench Audio, a subset of Full Duplex Bench, and τ-Voice with equal weights to assess speech reasoning, conversational dynamics, and agentic performance. Models are included only if they have valid results on all three datasets.
A company evaluating voice interfaces could implement a testing process with comparable criteria for these capabilities, record results by version, and track regressions before updating a system. The practical response is to build evaluation and monitoring; the index alone does not determine which model fits a particular operation.
