Free Hindi AI Voice Agent (2026): What 50 Free Credits Get You

What a free Hindi AI voice agent actually is

People who search for a free AI voice agent, or for voice agents free of charge, usually run into three different products under one label. They behave very differently once the first call is placed, so it helps to separate them before comparing anything.

1. 01A text-to-speech tool that reads a Hindi script aloud. It is often free, but it only produces audio. It cannot dial a number, hear a reply, answer or record an outcome.
2. 02A trial of a real calling agent, with a small allowance of minutes. Real calls cost money because a carrier connects them, speech has to be recognised, a reply has to be decided and a voice has to say it, so the allowance is always limited.
3. 03A free-forever plan. For live phone calls in Hindi this is rare, because each minute has a real cost behind it, and no such plan exists at Outpero.

Outpero's offer is the second kind. Every new account receives 50 free credits at signup, with no card. One credit is ₹1, and credits are used only for connected talk time, so the free allowance behaves exactly like paid money. It never expires, which means there is no need to rush the test inside a week.

What the 50 free credits cover

• Building a Hindi AI voice agent: the call script, the opening line, the questions it should ask and the details it should capture.
• Real test calls, billed per connected minute at Standard ₹5 or Premium ₹6.8.
• The full output of each call: recording, transcript, summary, sentiment and the custom fields asked for, all visible in the dashboard.
• The Credits used figure on every call in the log, so the cost of each test is visible.

What free is not

• Not a free-forever plan. When the credits are used, further calls are paid per minute.
• Not a free phone number. A dedicated +91 business number is ₹649 a month, billed separately, and instant lead calling needs it. Do not plan on the free credits paying for it.
• Not a volume pilot. The minutes are for testing real conversations, not for running a campaign across a lead list.
• Not a voice-over generator. The point is a live conversation in Hindi, not a downloadable audio clip.

How the Hindi agent is built and tested before calls begin

The agent is built and tested inside the app, and most of the work happens before a single credit is spent. That ordering matters, because a script that is wrong costs the same per minute as a script that is right.

1. 01Write the call script in the words the customer uses. In the Hindi belt that means Hinglish nouns such as site visit, EMI, delivery and booking sitting inside ordinary Hindi sentences, not textbook Hindi.
2. 02Preview the voice. The voice preview is free, so listen to Standard and Premium, adjust the speed, and choose before any call is placed.
3. 03Run the sandbox chat to test the script as text, trying odd answers, refusals and half-answers to see where the script breaks.
4. 04Only then place calls, first to your own phone, then to a colleague's, then to two or three people who speak the way your customers do.

What 50 free credits buy in Hindi calls: an illustrative worked example

The table is illustrative, not a measurement. The call lengths are assumptions chosen to show the arithmetic, and a real call will run shorter or longer depending on the caller. The rates are the published self-serve ones: Standard ₹5 and Premium ₹6.8 per connected minute. Unanswered calls are not billed.

Two points follow from the table. First, the short, plain call types stretch furthest, so test the opening and the main question on short calls and save the longer calls for the scenarios that matter most to the business. Second, trying Premium on one or two calls costs a little more per minute but is an easy way to hear the difference, which is why a mixed plan is sensible: mostly Standard, with one Premium call as a comparison.

A 10-call test plan for a Hindi AI voice agent

Ten short calls of about one minute use roughly 10 minutes, which is the whole free allowance on Standard. The plan below makes each call answer a specific question, so no credit is spent on a call that proves nothing.

1. 01Call 1 and 2, the plain path: answer the way a cooperative customer would, in clean Hindi, and check that the opening line, the pacing and the summary are acceptable.
2. 02Call 3, interruption: cut in halfway through the agent's sentence with a question, and see whether it stops and answers or talks over you.
3. 03Call 4, Hinglish: speak naturally with English nouns, such as booking, receipt and balance, in Hindi grammar, and check that the agent follows without asking you to repeat.
4. 04Call 5, numbers: give an amount in words, such as पैंतालीस हज़ार, and a date such as बारह तारीख, then compare the transcript and captured fields with what was said.
5. 05Call 6, names and places: give a name like त्रिपाठी or मीणा and a locality like कंकड़बाग, and check the spelling in the log.
6. 06Call 7, a different person answers: pretend to be a family member and say that the person asked for is out. The agent should be polite and ask when to call back.
7. 07Call 8, refusal: say that no interest remains, and check that the agent accepts it gracefully and the outcome is logged as not interested.
8. 08Call 9, noise: call from a busy road or with a speakerphone, as many real customers do.
9. 09Call 10, the repeat: after editing the script from what calls 1 to 9 showed, run one call that repeats the weakest scenario.

Read the transcript after every call, not only at the end. A call that sounded fine to the ear can still capture a wrong figure, and the log is where that shows up.

A Hindi test line in Devanagari

A good test line carries a callback time, a budget in words and an English noun, all in one breath. The scenario here is a furniture showroom in Jaipur calling back a sofa enquiry. The agent opens:

नमस्ते त्रिपाठी जी, मैं Mansarovar Furnishers की AI voice assistant बोल रही हूँ। आपने sofa set के बारे में enquiry की थी, क्या अभी दो मिनट बात हो सकती है?

English gloss: Hello Mr Tripathi, I am an AI voice assistant from Mansarovar Furnishers. You enquired about a sofa set, can we talk for two minutes now? The tester then answers with the line below.

अभी तो मैं meeting में हूँ, शाम को सात बजे के बाद फ़ोन कर लीजिए, और हाँ budget पैंतालीस हज़ार तक का है।

English gloss: I am in a meeting right now, call after seven in the evening, and yes, the budget is up to forty-five thousand. A correct result is a callback time near 7 pm and a budget field of 45,000, with the English words meeting and budget causing no hiccup. If either is wrong, the transcript shows where, and the script or the extract hint can be changed before the next call.

Hindi-belt caller realities worth building into the test

• Delhi NCR and Haryana: callers are fast and mix English heavily, and some will not pick up unknown numbers during work hours. A Laxmi Nagar shopkeeper and a Gurugram professional will both cut an agent off after one sentence, so the opening must reach the point quickly.
• Uttar Pradesh: in Kanpur, Lucknow and Varanasi the aap form and a courteous pace matter more than speed, and a family member often answers a phone that belongs to someone else.
• Rajasthan: greetings and rhythm differ in Jaipur, Jodhpur and Kota, and pickup times may differ from the Delhi pattern. Test with someone who actually speaks that way, since results here should be treated as unproven until heard.
• Madhya Pradesh: Indore and Bhopal callers mix English comfortably, but a smaller-town caller from Jabalpur or Sagar may answer in short, clipped phrases that make the agent's follow-up questions the real test.
• Bihar: Patna and Gaya callers sometimes slip in Bhojpuri or Maithili words. Outpero handles ordinary Hindi, does not claim per-dialect training, and does not support Bhojpuri as a language, so listen to what happens when a word it does not know appears.

The agent speaks one neutral spoken register everywhere. That is why a short pilot on callers from the region that matters, and not a single polished demo, is the honest way to decide.

What other 'free' claims usually hide

Without naming any vendor, a handful of patterns recur in free offers for voice agents. They are worth checking for in every product, including this one.

• A demo that is really text-to-speech. A browser page that speaks a Hindi sentence to you is not a calling agent. Ask whether the free test places an actual call to an actual phone and listens to the answer.
• Trial minutes plus telephony billed separately. Some trials give minutes of voice but charge for the phone line, the number or the carrier on top, so the real cost of a test call is not the headline figure.
• A card on file that converts quietly. Check whether a card is needed to start, and what happens on day 8.
• Minutes that expire. A trial with a deadline pushes testing into a rush. Outpero's credits do not expire.
• Hindi that is an add-on. Confirm that the free test runs in the language you will actually use, not only English.

Outpero publishes this page, so apply the same checklist to Outpero. The figures here are the ones the app shows at signup, and the Credits used column in the call log is the way to verify them.

What the free test cannot tell you

Fifty credits settle a lot: whether the voice is acceptable, whether the Hinglish flow works, and whether the captured fields are usable. They cannot settle pickup rates on a cold list, conversion into sales, or how a campaign behaves across thousands of contacts. Those need a paid pilot with real leads.

Two operational costs sit outside the free credits. A dedicated number is ₹649 a month and includes one channel, where a channel is one call at a time. An extra channel is another ₹649 a month. For instant lead calling, where a new enquiry from a Meta ad or a 99acres listing is called within 30 seconds of arriving (depending on how fast the lead source delivers it), the number is required.

When the 50 credits run out

Top up prepaid credits and carry on paying only for connected talk time. There is no subscription, no setup fee and no contract. Outpero's pricing starts from ₹3.5/min on custom plans (₹5/min self-serve), with Standard at ₹5 and Premium at ₹6.8 per minute for self-serve accounts. High volumes get custom rates and setup help.

For scale, a human telecaller in India costs roughly ₹18,000 a month for a single shift and handles one call at a time. At ₹5 a minute, the same ₹18,000 buys about 3,600 connected minutes of Hindi AI calling, all prices excluding 18% GST.
