Hindi as spoken in Nagpur
Varhadi Marathi, materially different from Puneri standard and largely missing from public corpora.
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.

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
