Can offline AI handle Hindi?
हिन्दी in speech, text and translation: what the model cards and papers actually report.

Hindi (हिन्दी) is written in Devanagari. Article 343 of the Constitution names “Hindi in Devanagari script” as the official language of the Union (general information, not legal advice). The 2011 Census counted 52,83,47,193 people with Hindi as their mother tongue, 43.63% of India and the largest language group. Uttar Pradesh alone had 18,79,79,055, followed by Bihar (8,06,98,466), Madhya Pradesh (6,43,24,963) and Rajasthan (6,12,74,274).

The Census puts 56 named mother tongues under Hindi, among them Bhojpuri (5,05,79,447 speakers), Rajasthani (2,58,06,344), Chhattisgarhi (1,62,45,190) and Magadhi (1,27,06,825). Hindi proper accounts for 32,22,30,097, about 61% of the group. The Home Ministry says it has not been possible to fix a criterion that separates a language from a dialect, so where “Hindi” ends is a judgement. For speech recognition it means your speakers may sound unlike the people in any one test set: the IndicVoices paper says budget limits meant skipping about 40% of the districts where Hindi and Urdu are spoken.

In offices, English nouns, rupee figures and names often sit inside Hindi sentences, and chat is often typed in Roman letters. That mixed form has its own page, Hinglish; the tests below apply to both.

• Record ten minutes of a real meeting, not a read-aloud script, and correct the transcript by hand. Divide the wrong words by the total. The paper figures above are for read sentences and for one set of speakers.
• Check numbers, dates and rupee amounts said aloud (“do lakh pachas hazaar”), and the names of people and places.
• Check which script the output uses when a speaker says an English word: Devanagari, Roman letters, or a translation.
• Play recordings with background noise and long silences. Whisper’s card warns that the model may print text that was not spoken, and its paper lists repeat loops and unrelated output among known failures.
• Test speakers from different regions: a Bhojpuri-influenced accent, a Rajasthani one and a Haryanvi one (98,06,519 Census speakers).
• For translation, compare the output with a human version of a real notice. NLLB-200’s card says its translations cannot be used as certified translations.

ANVE’s meeting-minutes maker handles Hindi, English and Hinglish transcripts today. Every action item must quote the transcript line it came from, and a person must confirm each owner before the item is approved; each confirmation is logged. This runs in the development build: ANVE is pre-release, with no sealed unit and no customers yet.

ANVE has published no Hindi accuracy figure, so the numbers on this page describe the open models, not ANVE. A voice front desk that answers callers in Hindi or English is something ANVE could build in a paid pilot, on AnveVoice; it is not a shipped product. ANVE One’s launch default is a 27B-class model, Qwen 3.8 27B. Its card lists no languages, so the Qwen evidence above comes from the Qwen3 launch post, and the Qwen3.5 card, which says 201 languages and dialects.

A better Hindi model would reach an ANVE box as an update. At present ANVEAI installs updates on site, signed packages applied offline by USB are not on ANVE yet, and ANVE never updates itself over the internet.

No sealed ANVE unit exists; every image of the appliance on this site is a labelled render. The software runs today on a development machine. No customers yet, no certifications, no delivery date, and the final price is not announced.

Reservations are ₹999 in India or US$12 elsewhere, refundable in full until you confirm an order in writing (terms). Offices that cannot use cloud AI can apply to be one of ten design partners.
