Voice agent evaluationCustom-scoped evaluation set

Voice agent evaluation data for accents, noise, and real call conditions

Build a private test set around the callers, channels, languages, and failure modes your voice agent actually faces. Spirelight scopes the collection, reference transcripts, slices, and holdout rules with your team.

Sample availability: Submit your language and channel requirements. The team reviews the request manually and confirms whether an applicable conversational or telephony example is currently available.

Collection specification

Wideband, narrowband, mono, or separate channels by project
Coverage
Accents, languages, SNR bands, interruptions, overlap, and domain scenarios
References

Holdout
Collection split and non-reuse terms documented in the project scope
Delivery
Audio, transcripts, metadata, split manifest, and evaluation brief

Test the conditions hidden by a single average score

A useful voice-agent evaluation set separates accent, language, channel, noise, interruption, and scenario effects. The result is not just one word error rate. It shows which caller groups and conditions cause the system to fail.

The collection is scoped around your deployment. If a hosted model cannot be fine-tuned, the same held-out set can still compare providers and detect regressions after each release.

Keep evaluation audio out of the training delivery

Training leakage makes a benchmark look better without making the production system better. We define the evaluation split, file manifest, access rules, and any non-reuse commitment in the statement of work before recording starts.

This offer is not the right fit when

  • You need a public benchmark with unrestricted redistribution.
  • You cannot describe the deployment channel, language, or main failure mode.
  • You need an immediately downloadable fixed pack without a scoping step.
Prepare the brief

Bring a specification your vendors can price consistently

Use the free worksheet to define coverage, rights, delivery fields, held-out rules, and acceptance tests before requesting a collection plan.

Sample availability

Check sample availability

Submit your language and channel requirements. The team reviews the request manually and confirms whether an applicable conversational or telephony example is currently available.

Enter your work email and verify it with a 6-digit code. An admin reviews the request and confirms whether an applicable example is currently available and may be shared. Use the optional field to name the language, channel, or condition you need to inspect.
