Hindi as spoken in Bengaluru
Urban Kannada under heavy multilingual contact; the strongest Indian English pool in the country.
Urban Hindi speech is Hinglish in practice. Expect 15-40% English tokens in spontaneous speech: numbers, brands, technology terms, and whole clause switches. Any Hindi corpus that excludes English tokens will not match production traffic.
Recruitment here
Excellent for Indian English accent bands and technology-domain speakers; native Kannada requires residence screening.
Largest recruitment pool in the network. A 1,000-speaker Hindi cohort with balanced gender and 18-45 age bands is typically fielded across four cities to avoid a single-city accent bias.

Studio setup
Two booths with far-field and device-distance rigs for wake-word capture.
Hindi quality rules
- Inconsistent Devanagari vs romanised spelling for the same English loan word
- Nukta characters (क़ ख़ ग़ ज़ फ़) applied inconsistently by transcribers
- Numerals: whether to write digits, Devanagari numerals, or spelled-out words must be fixed in the style guide up front
- Honorific verb forms create long agreement chains that annotators shorten unless the guide forbids it
Session types available
- Scripted prompt reading (phonetically balanced sentence sets)
- Wake-word and command-and-control utterances
- Digit strings, dates, amounts, and Indian address formats
- Two-party spontaneous conversation on everyday topics
- Simulated call-centre calls: billing, delivery, recharge, banking

| Region | Uttar Pradesh / Bihar / Madhya Pradesh and others | Dialect spread across 7 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 |
