Call Centre Speech Data: cost and pricing in India
Indicative rate bands for call centre speech data, the five specification decisions that move the number most, and how a fixed quote is put together from a written spec.

- Pricing model
- Per delivered unit, fixed against spec
- Minimum
- ~50 hours or equivalent per language
- Turnaround
- 3-6 weeks for 100-250 hours.
- Quote time
- One working day
What drives the price of call-centre speech
Simulated and consented real-world contact-centre audio in Indian languages, recorded over telephony-grade channels so it matches the bandwidth your production system actually sees.
- Language tier: widely spoken languages have deeper recruitment pools and cost less per unit than low-resource ones
- Demographic narrowness: a 50/50 gender split across three age bands is routine; a narrow cohort multiplies recruitment effort
- Channel — 8 kHz narrowband telephony plus 48 kHz reference where required. Moving this off the standard changes the unit cost directly.
- Codec — G.711 / Opus simulated to match your stack. Moving this off the standard changes the unit cost directly.
- Structure — Agent and customer on separate channels. Moving this off the standard changes the unit cost directly.
- Scenarios — Billing, delivery, KYC, recharge, collections, support, sales. Moving this off the standard changes the unit cost directly.
- QA threshold and rework policy: a higher accept bar means more re-collection, which is priced in rather than absorbed later
Where the cost sits in call-centre speech
Speakers with and without prior contact-centre experience, mixed to the ratio you specify.
Turnaround: 3-6 weeks for 100-250 hours.

Indicative rate bands
| Scope | Unit | Indicative band |
|---|---|---|
| Widely spoken language, standard spec | per delivered hour | ₹3,200 – ₹6,500 |
| Regional language, standard spec | per delivered hour | ₹4,200 – ₹8,200 |
| Low-resource language or narrow cohort | per delivered hour | ₹5,500 – ₹11,000 |
| Verbatim transcription add-on | per audio hour | ₹900 – ₹2,400 |
| Pilot batch (10-20 hours) | fixed | Quoted separately, credited against the full run |
These are bands, not a price list. Two projects with the same hour count can differ by 3x on cohort design alone, which is why every number here is replaced by a fixed figure once we see your specification.
What the price includes
- Dual-channel call audio
- Verbatim transcripts
- Intent, outcome and sentiment labels
- Scenario coverage matrix
How the quote is built
- Scenario library built from your call taxonomy
- Agent-side speakers briefed on your script and tone
- Recording over the specified codec path
- Transcription with intent and outcome labels
- Delivery with per-scenario counts
Where budgets get wasted
The most expensive mistake in a data purchase is buying volume before the specification is settled. Re-collecting 200 hours because the noise profile did not match deployment costs more than the entire QA layer would have.
Narrowband is simulated at capture time, not by downsampling clean studio audio, which would leave unrealistic artefacts.

Frequently asked
How much does call-centre speech cost per hour in India?
Most programmes land between ₹3,200 and ₹11,000 per delivered unit depending on language tier, cohort narrowness, recording condition and annotation depth. A written specification converts that band into a single fixed number.
Is there a minimum order?
Around 50 hours or equivalent per language for a production run. Pilots of 10-20 hours are accepted when they lead into a larger build, since most setup cost sits in specification and recruitment.
Do you charge for rejected audio?
No. You pay for delivered units that pass the agreed QA threshold. Rejected material is re-collected at our cost.
Can the price be fixed rather than estimated?
Yes. Once the specification is signed the price is fixed against it. Changes to quotas, conditions or annotation depth are re-quoted before work continues.
