Hindi as spoken in Patna

Bhojpuri and Magahi-influenced Hindi, a major deployment market and a major corpus gap.

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
05

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
