Why Gujarati prices the way it does
Gujarati has roughly 55 million speakers concentrated in Gujarat, Daman & Diu, Dadra & Nagar Haveli, which sets how quickly a cohort can be recruited. Recruitment speed, not recording time, is the dominant cost in almost every programme.
Surat and Rajkot recruitment is essential for dialect coverage; Ahmedabad-only cohorts sound uniform.
- Business and trade vocabulary is heavily English; Gujarati diaspora speech adds further English structure. Specify whether diaspora speakers are in or out of scope.
- Very little spontaneous Gujarati audio exists publicly; nearly all of it is Ahmedabad read speech.
Worked budgets
| Volume | Typical speakers | Indicative range | Timeline |
|---|---|---|---|
| 100 hours | 200 at 30 min | ₹4,20,000 – ₹8,20,000 | 3-6 weeks |
| 500 hours | 1,000 at 30 min | ₹19,32,000 – ₹37,72,000 | 6-10 weeks |
| 1,000 hours | 2,000 at 30 min | ₹35,70,000 – ₹69,70,000 | 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 Standard (Amdavadi), Surti, Kathiyawadi, Kachchhi-influenced rather than one prestige variety adds recruitment cost but is what makes the corpus usable in production
- Script and transcription: Gujarati transcription needs native reviewers, and Breathy vowels have no consistent orthographic marking is the usual source of rework
- Phonetics: Murmured (breathy-voiced) vowels are phonemic in Gujarati and are absent from most shared Indic acoustic models, which requires reviewers trained on the language rather than generic annotators
Add-ons and their pricing

| Romanised parallel transcript | per audio hour | ₹500 – ₹1,200 |
| Speaker-disjoint train/dev/test splits | one-off | Included |
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 Gujarati speech data?
Indicatively ₹4,200 to ₹8,200 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 Gujarati 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.
