Make the stack work on your real audio.

Wordcab Adapt covers the work between a promising pilot and a production-ready rollout — data preparation, evaluation, fine-tuning, and validation against the audio conditions that matter.

Benchmark WER is not production WER.

Generic ASR degrades 2.8–5.7× from benchmark to production. Clean dictation: 8.7% WER. Multi-speaker contact-center audio on the same model: over 50%. That's the gap Adapt closes.

Targeted fine-tuning on 10–100 hours of representative audio typically yields 10–30% relative WER reduction. No retraining from scratch. No customer audio leaving the boundary.

The gap is real

92% accuracy on clean headsets drops to 78% in a conference room and 65% on a mobile call. Your rollout sees the worst end.

Adapt closes it

10–100 hours of labeled domain audio, prepared and tuned inside your infrastructure. Iterate weekly — not quarterly.

This is the productionization layer.

01 — Data

Data intake and cleanup

Prepare raw customer audio in approved environments.

Audio comes in messy — noisy recordings, overlapping speakers, inconsistent formats. Data preparation happens inside the customer's approved infrastructure, not in an external pipeline the security team cannot inspect.

02 — Evaluation

Evaluation and benchmarking

Test model options against the workflow and the success criteria that matter.

Benchmarks should match the actual workload — not a generic test set. Evaluate model candidates against real audio conditions, domain vocabulary, and the quality bar the downstream workflow requires.

03 — Fine-tuning

Fine-tuning and adaptation

Improve performance on specialized language, accents, telephony audio, and multi-speaker conversations.

When the default model is close but not close enough, fine-tuning closes the gap. Domain vocabulary, accent coverage, and telephony noise handling improve without starting from scratch.

04 — Validation

Rollout validation

Confirm that the stack is ready before wider deployment.

Validate before the rollout starts grading you. Run the tuned stack against held-out data, confirm the quality metrics, and make sure the system performs in the conditions that matter.

Evaluate the model stack against the workflow, not the hype.

Frequently asked questions

We are close on quality, but not close enough. Is Adapt meant for that middle ground?
Yes. That's exactly where teams get stuck. The model is not obviously broken — just too noisy for a production workflow. Adapt exists to close that gap.
Is Adapt only about fine-tuning?
No. Evaluation, data preparation, prompt and stack selection, and rollout validation matter just as much. Fine-tuning is only useful when it's attached to the actual workflow.
Can adaptation happen inside approved environments?
Yes. That matters for customers working with sensitive audio or controlled data paths.
Do all customers need Adapt?
No. Some teams can start with Voice alone. Adapt becomes important when domain language, workflow quality, or messy audio threatens adoption.

Get to production quality before the rollout starts grading you.

If your team already knows generic voice models will struggle on real production audio — Wordcab Adapt is the clearer path to usable performance.
