Hinglish Training Data for ML Research Groups
Academic and industrial research teams building benchmarks and studying low-resource Indian languages, where documentation and reproducibility matter as much as volume. For Hinglish specifically, the work is shaped by 4 dialect varieties and by how much English enters the speech.

- Buyer profile
- ML Research Groups
- Language
- Hinglish (hi-Latn-IN)
- Typical ask
- 20-200 hours in one or more low-resource languages with full protocol documentation.
Your problem
- Low-resource languages have no usable public data at all
- Datasets without documented collection protocols cannot be cited or reproduced
- Ethics and consent requirements are stricter than commercial norms
What Hinglish requires
- Intra-sentential switching means English words carry Indian phonology, so English acoustic models mis-transcribe them
- Dialects: Delhi corporate Hinglish, Mumbai Bambaiya, Call-centre register, Youth/social media register
- Hinglish is the code-mixing case itself. Typical urban customer-support speech is 30-60% English tokens embedded in Hindi grammar, with switching several times per utterance.
- Almost no public corpus contains genuine intra-sentential Hindi-English switching with per-token language tags. This is the highest-value gap for anyone building Indian conversational AI.

How you will evaluate the delivery
- Is the collection protocol documented well enough to publish?
- Are speaker demographics reported in aggregate for dataset cards?
- Can the data be released openly, and under what consent terms?
Recommended cohort
Recruit by switching behaviour, not by language proficiency. Screening recordings are used to confirm speakers switch naturally rather than performing one language.
| Dimension | Typical split | Why it matters for Hinglish |
|---|---|---|
| Gender | 50 / 50 | Pitch range differences change acoustic model behaviour; unbalanced cohorts bias recognition |
| Age | 18-25: 30%, 26-40: 40%, 41-60: 30% | Older speakers retain conservative Hinglish forms that younger urban speakers have lost |
| Region | Delhi NCR / Mumbai / Bengaluru and others | Dialect spread across 4 recognised varieties |
| Education | Mixed, including below-graduate | Prompt-reading fluency correlates with education and skews prosody |
| Condition | Studio / quiet room / field | Match the noise profile of your deployment |
Contract points
- Open-release-compatible consent
- Dataset card material provided with delivery
- Attribution and citation terms
Example requirement
"We need 2,000 hours of Hinglish from 3,000 speakers, 50/50 male-female, ages 18-45, studio quality, scripted plus spontaneous, delivered in WAV with transcripts."
That sentence is enough to produce a quote and a timeline. Anything missing, we will ask about once.
Frequently asked
Do you have Hinglish capacity available now?
Recruit by switching behaviour, not by language proficiency. Screening recordings are used to confirm speakers switch naturally rather than performing one language. Fielding usually starts one to two weeks after the specification is signed.
Can you work white-label?
Yes, including QA reporting written so it can be passed to your end client unchanged.
What licensing applies to Hinglish data?
Perpetual and transferable, with participant consent covering model training and downstream distribution. Open-release-compatible consent is addressed in the master agreement.
