Controlled scenarios
Hold the caller goals and workflow requirements constant across every candidate.
For vendor comparisons
Run the same workflow, caller, audio, and scoring contract across every vendor so trade-offs become visible before procurement.
Why this needs evaluation
What Voxeval proves
Hold the caller goals and workflow requirements constant across every candidate.
Separate speech, reasoning, orchestration, tool, and telephony failures instead of averaging them together.
Show where each stack wins, where it breaks, and what that means for the target workflow.
Evaluation sequence
Define one shared evaluation contract.
Run equivalent calls against each candidate.
Compare outcomes and failure layers side by side.
