01
Representative speech
Bring real tasks, accents, age groups, devices and recording conditions—not only clean studio audio.
/platform
The assessment core behind every Chivox product.
One shared platform supports two language-specific scoring engines. Scoring, diagnosis and open-ended evaluation are the common capabilities underneath both.
/evidence-at-scaleIn production
50M+
Hours of learner speech behind the assessment models.
- Research started at Cambridge
- 2007
- Recordings scored
- 8B+
- Countries served
- 182
Built from long-running speech research and real-world learner audio—not transcript-only inference.
/evaluate-with-your-data
Validate the product decision, not just the score.
Speech performance changes with task design, language level and recording quality. A useful pilot tests the full path from captured audio to the feedback your user sees.
02
Human review
Compare the returned evidence with your own rubric and subject-matter reviewers on the cases that matter most.
03
Product behavior
Define what passes, what gets a focused retry, and what should be rejected because the audio is not usable.
04
Production envelope
Confirm expected traffic, latency, data handling, environments, limits and support before launch.

/capabilities
Three shared capabilities behind both engines.
These are platform capabilities, not separate scoring engines or customer scenarios.
/languages
Two languages, two scoring engines.
English and Mandarin need different acoustic models and rubrics. Age, classroom, device and testing contexts are handled in the use-case layer.
/delivery
Three ways to call the same core.
See the same request and response side by side on the integrations page.
