Hindi, done properly
The details Indian callers notice in one sentence.
- Verbs match the voice: a female agent says “कर रही हूँ”, a male agent “कर रहा हूँ”.
- Honorifics match the caller. If the caller's gender isn't known, it says “Meena जी” instead of guessing.
- Plain phone words: “enquiry”, “performance”, “fees”, not literary Hindi nobody uses on a call.
- Numbers are spoken as words, phone numbers digit by digit, and times in the 12-hour clock.
- The greeting fits the time of day. No “good morning” at 7 pm.

Sounds like a phone call
Tuned for an 8 kHz phone line, not a podcast.
Studio-quality AI voices sound wrong on a phone call: too crisp, too close, too quiet in the background. Telleo shapes the voice to the telephone band and adds a faint room tone, so the agent sounds like someone at a calling desk.
The live voice pipeline runs on servers in Mumbai, next to the Indian phone network.
The voice library
80+ voices across seven speech engines.
Pick by ear. Every voice can be auditioned with your own opening line before you save the agent, and the preview uses the same engine and settings as the live call.

Frequently asked questions
How many voices are there?+
More than 80, male and female, across seven speech engines. You can audition any of them before you choose, and the preview uses the same engine, voice and pace the call will use (the phone-line shaping is added on the live call).
Can the agent switch languages mid-call?+
Callers often mix Hindi and English, and a Hinglish agent handles that naturally. Each agent has a main language; it stays in it rather than drifting, which keeps calls consistent.
Why write Hindi in Devanagari?+
Indian voice engines pronounce Hindi best when it is written in Devanagari, with English business words like demo, fees or booking kept in English. Romanised Hindi reads worse on the phone, so Telleo's scripts and replies follow that rule.
Can you clone our own voice?+
Not today. Choose from the voice library; we can help you pick one that fits your brand and your callers.
Will it pronounce our brand name correctly?+
Test it in the voice preview. If a name comes out wrong, we adjust how it is written in the script until it sounds right on the phone.
Do you support regional languages?+
The voice engines support Tamil, Telugu, Marathi, Bengali, Gujarati, Kannada, Malayalam, Punjabi and Odia. We set these up with you and test them on real calls before you rely on them; Hindi, English and Hinglish are the languages in production today.
