Answering the support line in the caller's own Indian language
One number answers in Hindi, Tamil, Marathi or code-mixed Hinglish: the language is identified from the caller's first utterance, recognition and reply run in that language throughout, and a bilingual colleague inherits the transcript when the call is handed over.

What to check before you ship it in India
- Answering in Marathi and then serving the consent notice in English only is half a system. Section 5(3) requires the Data Fiduciary to give the Data Principal the option to access the contents of the notice in English or any language specified in the Eighth Schedule to the Constitution, so the notice needs the same language coverage the line advertises.
- The failure mode is not a wrong word, it is a confident wrong word. A misheard amount or account number comes back as fluent speech, and the caller cannot see the transcript the system is acting on, so critical values have to be read back and confirmed explicitly before anything is committed. This is design reasoning, not a benchmark finding: no evaluation cited here measures read-back, and the caller has no transcript to check.
