Tamil as spoken in Bengaluru
Urban Kannada under heavy multilingual contact; the strongest Indian English pool in the country.
Tanglish is the default urban register. Technology, finance, and workplace vocabulary is largely English embedded in Tamil syntax.
Recruitment here
Excellent for Indian English accent bands and technology-domain speakers; native Kannada requires residence screening.
Recruit by district rather than by city alone; Chennai-only cohorts produce models that degrade sharply in the south and west of the state.
Studio setup
Two booths with far-field and device-distance rigs for wake-word capture.
Tamil quality rules
- Transcribers normalising spoken Tamil into literary Tamil, destroying the acoustic-text alignment
- ழ / ள / ல confusion
- Inconsistent handling of English insertions: Tamil script transliteration vs Latin script must be fixed in the guide
Session types available
- Colloquial spontaneous conversation transcribed verbatim
- Diglossia pairs: the same content in written and spoken register
- Command-and-control and IVR-style utterances
- District-level dialect elicitation
Building a balanced cohort
A Bengaluru-only cohort is appropriate when you are targeting this market specifically. For a general Tamil model, spread the cohort across Chennai, Coimbatore, Madurai as well.
| Dimension | Typical split | Why it matters for Tamil |
|---|---|---|
| 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 Tamil forms that younger urban speakers have lost |
| Region | Tamil Nadu / Puducherry / parts of Karnataka and Kerala and others | Dialect spread across 6 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 |
