Yes, interesting learnt something new about my own culture today! Apple has called it Hindi and they’ve got dictation to Devanagari which is super responsive and accurate - a pleasant surprise.
They could also, for example, have support for Nepali, which is also normally written in the same alphabet but is definitely a different language from Hindi. In that case the language support would be different at a software level, like the vocabulary and/or grammatical patterns that the speech-to-text system is trying to recognize.
The problem (whether for a computer or a human being!) of figuring out what language something is actually written in can be tricky when many languages use identical or related scripts:
