Hinglish is the default, not an edge case
Speech-to-text from Sarvam Saaras v4 and Soniox transcribes mixed Hindi-English speech as spoken, so 'EMI kab due hai' is understood as one sentence rather than forced into one language.

Hindi voice AI agents that talk the way your customers do.
Most Hindi calls are really Hinglish: EMI, due date and salary stay in English inside Hindi sentences. Vocily agents understand the mix, reply with a native Hindi voice and switch to English when the caller does.
On the phone in Hindi
52.8 crore people speak Hindi as their first language.
Mainly in Uttar Pradesh, Bihar, Madhya Pradesh, Rajasthan, Delhi, Haryana and across North India (Census of India, 2011). Here is what it takes for an agent to sound right to them.
More speech models than any other Indian language
Hindi is the one Indic language Deepgram supports, so a Hindi agent can choose between Sarvam, Soniox and Deepgram Nova 3 or Flux, and fall back to another provider if one lags.
Amounts and dates read the way callers expect
Choose how the agent reads rupee amounts, dates and phone numbers aloud, and add your brand and product names to keyword boosting so they are never misheard.
Sample call
A Hindi EMI reminder call
An outbound reminder from a lender's agent, with the caller asking for more time.
नमस्ते राहुल जी, मैं सहाय फाइनेंस से बोल रही हूँ। आपकी ₹4,500 की EMI 5 तारीख को due है, बस याद दिलाने के लिए कॉल किया।
Hello Rahul ji, I'm calling from Sahay Finance. Your ₹4,500 EMI is due on the 5th; just calling to remind you.
हाँ, पता है, पर इस बार salary थोड़ा late आएगी, 8 तारीख तक।
Yes, I know, but my salary is a bit late this time, by the 8th.
कोई बात नहीं। क्या मैं 8 तारीख का payment promise note कर लूँ?
No problem. Shall I note a payment promise for the 8th?
हाँ, ठीक है, 8 को कर दूँगा।
Yes, fine, I'll pay on the 8th.
धन्यवाद राहुल जी, 8 तारीख का promise note कर लिया है। आपका दिन शुभ हो!
Thank you Rahul ji, I've noted the promise for the 8th. Have a good day!
The promise-to-pay date is written to the lender's system through an API tool.
