Can voice agents speak Indian languages?
Yes. Modern speech models support Hindi, Telugu, Tamil and other Indian languages as well as English. We test quality for each language before launch.
Do callers know they are talking to AI?
We recommend clearly disclosing that the caller is speaking with an AI assistant and offering a way to reach a person.
