AI voice agents speak Hindi and regional Indian languages in production today, including code-mixed Hinglish that real callers actually use.
Yes. AI voice agents handle Hindi and regional Indian languages in production right now, and they handle the code-mixed Hinglish real callers actually speak. We built Battery Smart's Hindi voice agent on Sarvam AI's Indian-language speech-to-text and text-to-speech, wired into live driver, battery, and station APIs, and it resolves in-scope support calls end to end with zero human handoff. The same architecture extends to Tamil, Telugu, Marathi, Bengali, and other regional languages by swapping the speech models and retuning the prompts. The hard part is never the language label; it is accented, noisy, real-world audio and mixed-language sentences. That is exactly what Indian-first speech models like Sarvam are trained for, which is why we use them.
Generic English-first speech engines fail on Indian audio because they were never trained on it. Indian-language models handle the accents, the switching between Hindi and English mid-sentence, and phone-quality audio that Western stacks choke on.
Adding a language is a retuning exercise, not a rebuild: the telephony, agent logic, and integrations stay the same while the speech-to-text and text-to-speech layers change.
