STT: new language `hi-dev` (Devanagari-only Hindi)
Pulse STT streaming supports a new Hindi language code, hi-dev, that transcribes Hindi audio using a pure-Hindi model and writes everything in Devanagari.
The existing hi code stays as the bilingual model: it transcribes Hindi speech but renders borrowed English words in Roman script, producing mixed-script output like मेरी email आईडी पर invoice भेज दीजिए.
hi-dev uses the pure-Hindi model to keep the output script-consistent: मेरी ईमेल आईडी पर इनवॉइस भेज दीजिए.
Pick hi-dev when the downstream consumer needs Devanagari-only text (Devanagari-only UIs, government or regulated formatting, Hindi NLP pipelines that break on Latin characters). Stay on hi for customer-support and tech-support transcripts where recognisable English terms in Roman script are preferable.
Numbers. Pass itn_normalize=true to convert numbers spoken in Hindi to digits (पच्चीस हज़ार रुपए becomes ₹25000). Numbers spoken in English are written as Devanagari words and are not converted.
