Voice AI agent development in Surat: AI calling agents for the calls your team keeps putting off
Payment reminders, appointment confirmations, enquiry follow-ups: short, repetitive phone calls that matter but slip when the day gets busy. Yukti AI, a voice AI agent development company in Surat, builds AI calling agents that hold a real conversation in Hindi, log the outcome and schedule the next call.
Reply the same day · Hindi, Gujarati, English · No obligation
A voice AI agent is software that makes or answers phone calls and holds a real spoken conversation: confirming an appointment, reminding a customer about a payment, or qualifying an enquiry. It then logs the outcome to your system. Yukti AI builds these on Exotel telephony with OpenAI's realtime voice model, including outbound payment-reminder calls in Hindi.
Our proof: a Hindi payment-reminder voice agent
Every business that gives credit has a list of customers who owe money and someone whose job is partly to ring them. The call is short and formulaic, and it is the first thing to be skipped on a busy day. We built an outbound voice agent for exactly that job. Read the full Hindi payment-reminder voice AI case study; the short version:
| Part | What it does |
|---|---|
| Customer list | Supabase holds name, amount due, call time and status, mirrored to a Google Sheet for staff |
| Call scheduler (n8n) | Every 5 minutes, finds customers whose call is due and places the call |
| Telephony | Exotel outbound calling, streaming audio to the AI bridge |
| Conversation | A FastAPI media bridge connects the call to OpenAI's Realtime voice API; the agent speaks fluent Hindi and can be interrupted |
| Outcome | Logs paid, promise-to-pay, no-answer or other, and saves the full transcript |
| Follow-up scheduler (n8n) | Re-queues unpaid outcomes for another call about a day later |
Status, honestly: built and tested end to end — a real call was placed, the agent spoke fluent Hindi and the outcome was logged correctly. Calling at volume is waiting on the telephony provider's KYC, which every business needs to clear in India before automated calling at scale.
Where voice AI agents fit for Indian SMEs
- Payment and collection reminders for traders, distributors and manufacturers who extend credit.
- Appointment confirmations and reminders for clinics and healthcare providers, with the reply written back to the booking list.
- Admission and fee follow-ups for schools and coaching institutes.
- Enquiry call-backs: calling a new lead from a form or ad, asking two or three qualifying questions and logging the answers in your CRM.
- Order and delivery confirmations before dispatch, especially for cash-on-delivery orders.
Voice call or WhatsApp message?
A WhatsApp reminder is cheap and easy to send, and also easy to ignore. A phone call gets a response. Many businesses are best served by both: a WhatsApp AI chatbot for questions and catalogue sharing, and a voice agent for the calls that need an answer. The two can share the same customer list and log results to the same place.
Honest limits of voice AI today
- Keep the job narrow. A voice agent works best on one well-defined call, like a reminder or a confirmation. Open-ended sales calls and complaints still need a person.
- Phone lines are noisy. Poor networks, background noise and strong regional accents cause misheard words. We test on real calls and design the agent to confirm key details.
- It must not improvise commitments. Our agents are instructed to remind, note the response and defer anything they cannot answer, never to offer discounts or new terms.
- Telephony rules apply. Indian telephony providers require KYC, and automated calling has to follow calling-hour and consent rules. We plan those into the project.
- Running costs are per call. You pay telephony minutes plus AI usage. For short reminder calls this is usually small, but we estimate it with you before launch.

Free workflow audit
A 30-minute call about which calls your team makes or misses, and whether voice is the right channel.
Call design
We write the agent's instructions in your language and tone, list the replies it must handle, and define the outcomes to log.
Real test calls
The agent calls test numbers only, so you can hear it, check the transcripts and correct it before any customer is called.
Telephony and go-live
After the provider's KYC we switch on scheduled calling, connect results to your system and support it for 12 months.
How much does a voice AI agent cost?
Voice AI agents are quoted after a free workflow audit — the price depends on the requirement: how many calls, which languages, which systems the outcome updates, and the telephony setup. Running costs (telephony minutes and AI usage) are separate and paid as you use them. Focused builds — a Shopify store, one automation, a single-module system — typically take about 7–10 days. A multi-module ERP or CRM usually takes a few weeks depending on scope. A single voice use case is a focused build, but telephony KYC can add time before calling at volume.

Voice AI agent development in Surat: AI calling agents that speak Hindi
Voice AI agent development in Surat means building an AI calling agent that makes or answers phone calls and holds a short spoken conversation, then logs the outcome in your system. Yukti AI builds these on Exotel telephony and OpenAI’s Realtime voice API: the payment-reminder agent is built and tested, and appointment confirmations and enquiry follow-ups are calls we can build the same way. Pricing is quoted after a free workflow audit.
In Surat, phone calls still carry a lot of routine business work: a trader chasing payments, a clinic confirming tomorrow’s appointments, a school following up an admission enquiry. These calls are short, formulaic and easy to skip on a busy day. That is the sweet spot for a voice AI agent, and it is why we scope this work narrowly instead of promising a robot that can handle any call.
Which calls suit an AI voice calling agent
| Call | Who in Surat makes it | What the agent does | What it must not do |
|---|---|---|---|
| Payment reminder | Traders, distributors, manufacturers who sell on credit | Reminds, asks when the customer will pay, logs paid, promise-to-pay or no answer | Offer discounts or change terms |
| Appointment confirmation | Clinics, salons, coaching classes | Confirms or reschedules and writes the reply back to the booking list | Give medical advice |
| Enquiry call-back | Real estate, education, service businesses | Calls a new lead, asks two or three qualifying questions, logs answers in the CRM | Close a sale or quote a price on its own |
| Delivery or COD confirmation | E-commerce and wholesale dispatch teams | Confirms address and availability before dispatch | Change the order |
What is built, what is proven
The proof we can show is the Sureja payment-reminder voice agent. It is built and tested end to end: a real test call was placed, the agent spoke Hindi, and the outcome was logged correctly. It is not yet calling real customers, because calling at volume waits on the telephony provider’s KYC. Everything else in the table above is something we can build for you on the same stack. The detailed explanation is on voice AI payment reminder calls.
Choosing between a call and a message for one customer
Use WhatsApp when the customer wants to read, scroll a catalogue or reply later; use a call when you need an answer today. You can use both: a WhatsApp AI chatbot for questions and a voice agent for the reminders that get ignored in a chat. Both can write to the same customer record, whether that is a spreadsheet, Yukti AI CRM or your existing CRM through CRM automation.
Language, accent and noise on real phone lines
- Languages: Hindi is the language we have proven. English or Gujarati is set up through the agent’s instructions and tested on real calls before going live, because accents and mixed-language replies vary and a noisy line is harder than a clean demo.
- Narrow jobs only: the agent handles one defined call. Complaints and negotiations go to your team.
- Rules: Telephony providers ask for KYC and business verification, and calling-hour and consent rules may apply; check TRAI's and your provider's current rules. We plan for these in the project rather than discovering them at launch.
- Running costs: telephony minutes and AI usage are paid per call, separate from our build fee.
How to start
Send us the list of calls your team makes or misses in a week. In the free 30-minute workflow audit we decide whether voice is the right channel, which language mix you need and what each call should log. A focused voice use case is a focused build, though telephony KYC can add time before calling at volume.
