Evidence
Case studies
We do not publish client names, logos or invented numbers. What follows is how real programmes are shaped, plus exactly what we can show you privately under NDA.
- Named clients
- Only with written permission
- Under NDA
- Specs, QA reports, references
- Public proof
- Free sample recorded to your spec
- Fabricated metrics
- None
Why this page is short
Most data-vendor case studies are unverifiable. Client names are used without permission, accuracy figures have no stated measurement method, and the programme described is a composite. We would rather have a thin page than a dishonest one.
Every client contract we work under treats the specification as confidential, because a corpus specification reveals product roadmap. So the useful material is shared directly, under NDA, with buyers who are actually evaluating us.
Representative programme shapes
| Programme type | Typical shape | What decides success |
|---|---|---|
| Multi-dialect ASR corpus | 500-1,500 hours, one language, 5-8 districts, mixed conditions | Dialect quota design and native review depth |
| TTS voice build | 20-40 hours, 1-4 professional voices, studio, phonetically balanced | Script coverage and speaker consistency across sessions |
| Contact-centre model | 200-600 hours telephony, two-channel, domain vocabulary | Matching the real call path and noise profile |
| Wake word | Thousands of short utterances, many devices, many rooms, many distances | Variety of device and distance, not audio fidelity |
| LLM human data | Prompt-response pairs and preference ranking in Indian languages | Annotator instruction design and inter-annotator agreement |
What we can share under NDA
- A redacted specification and cohort design from a comparable programme
- A real QA report in the production format, with client identifiers removed
- A consent artefact and the retention and deletion process attached to it
- Named client references where those clients have agreed to speak
Better than a case study
The strongest evidence available to you is a free sample recorded to your own specification, followed by a paid pilot at your real cohort design. Both put files in your pipeline within weeks — which tells you more than any published narrative would.
Frequently asked
Why are there no client logos?
Because we do not have written permission to publish them. Vendors that display logos without permission are telling you how they will treat your confidentiality too.
Can we speak to a reference?
Yes, where a client has agreed to act as a reference for a comparable programme. Ask during evaluation and we will arrange it.
Can we see a real QA report?
Yes, redacted, under NDA. It is the single most useful document for judging a data vendor.
How else can we verify quality?
Request a free 30-minute sample recorded to your specification, then run it through your own pipeline.
