Why Assamese prices the way it does
Assamese has roughly 15 million speakers concentrated in Assam, Arunachal Pradesh, parts of Nagaland and Meghalaya, which sets how quickly a cohort can be recruited. Recruitment speed, not recording time, is the dominant cost in almost every programme.
Expect longer fielding times and higher per-hour cost than for Hindi or Marathi; the speaker pool with transcription-grade literacy is smaller.
- Assamese speech mixes Hindi, English and Bengali, with substantial contact influence in Barak Valley and tea-garden communities.
- Extremely low-resource. Almost no spontaneous Assamese speech data exists publicly, and non-standard dialects have none.
Worked budgets
| Volume | Typical speakers | Indicative range | Timeline |
|---|---|---|---|
| 100 hours | 200 at 30 min | ₹5,50,000 – ₹11,00,000 | 3-6 weeks |
| 500 hours | 1,000 at 30 min | ₹25,30,000 – ₹50,60,000 | 6-10 weeks |
| 1,000 hours | 2,000 at 30 min | ₹46,75,000 – ₹93,50,000 | 10-16 weeks |
Unit rates fall with volume because setup, script design and recruiter onboarding are amortised, not because quality is relaxed.

Cost drivers specific to this language
- Dialect spread: covering Kamrupi, Goalparia, Upper Assam (Sibsagar standard), Barak Valley contact varieties rather than one prestige variety adds recruitment cost but is what makes the corpus usable in production
- Script and transcription: Assamese (Eastern Nagari) transcription needs native reviewers, and Bengali characters substituted for Assamese ৰ / ৱ is the usual source of rework
- Phonetics: Assamese has the voiceless velar fricative /x/, unique among major Indian languages and routinely mis-modelled, which requires reviewers trained on the language rather than generic annotators

How to get the number down without hurting the model
- Widen the age bands before you widen the dialect spread — dialect coverage is what determines production accuracy
- Use quiet-room capture where deployment audio is not studio-clean anyway
- Order transcription in a second phase once the audio passes acceptance
- Run a 10-20 hour pilot; specification errors caught there are the cheapest ones you will ever fix
Frequently asked
What is the per-hour rate for Assamese speech data?
Indicatively ₹5,500 to ₹11,000 per delivered hour for standard scripted or spontaneous capture with verbatim transcription. Narrow cohorts and studio-only capture sit at the top of that band.
Is Assamese more expensive than Hindi?
Somewhat. Smaller recruitment pools mean more effort per speaker, which shows up as a higher per-hour rate rather than a longer timeline.
Do you quote in INR or USD?
Either. Bands here are in INR; international clients are usually invoiced in USD at a fixed contract rate.
What is included in the quoted rate?
Recruitment, consent capture, recording, QA, transcription if ordered, metadata, delivery packaging and a perpetual licence with full IP transfer.
