Voice AI Agent Pricing in India: What to Expect in 2026
Bolti is a voice AI platform for building production-ready conversational phone agents — and at ₹7/min pay-as-you-go with a free 50-minute trial, it's one of the most transparent pricing options available to Indian SMBs today. If you're evaluating voice AI for outbound sales, customer support, or HR screening, pricing is almost always the first filter. This guide breaks down exactly what you should expect to pay and why.
What Does Voice AI Agent Pricing in India Actually Look Like?
Most voice AI platforms charge per minute of call time, but the sticker rate rarely tells the full story. The real cost depends on how many components sit underneath each call — and who's paying for them.
A production voice call runs through at least four billable layers:
- STT (Speech-to-Text): Transcribes the caller's audio in real time. Providers like Deepgram, AssemblyAI, and Fennec (optimised for Indian languages) each have their own per-minute or per-second rates.
- LLM (Large Language Model): Decides what the agent says next. Billed per token by providers like OpenAI, Gemini, or Groq.
- TTS (Text-to-Speech): Synthesises the agent's reply into audio. Providers like ElevenLabs, Cartesia, and SarvamAI charge per character or per second.
- Telephony: The actual phone minute — PSTN or SIP — billed by your carrier or platform.
Some platforms bundle all four into a single per-minute rate. Others charge you the platform fee and expect you to bring your own API keys for STT, LLM, and TTS separately. Neither model is inherently better — it depends on your call volume and how much control you want.
How Bolti Prices Voice AI Calls
Bolti charges ₹7 per minute, all-in, on a pay-as-you-go basis. There's no monthly seat fee, no minimum commitment, and no credit card required to start. You get 50 free minutes to test with real phone calls before spending anything.
For context, here's what that looks like at different call volumes:
- 500 calls × 3 min avg = 1,500 min → ₹10,500/month
- 2,000 calls × 4 min avg = 8,000 min → ₹56,000/month
- 10,000 calls × 3 min avg = 30,000 min → ₹2,10,000/month
These numbers are predictable. You're not guessing at token counts or STT seconds — you pay for the minutes your agent is on the phone. See the full pricing breakdown on Bolti's pricing page for current rates and any volume tiers.
What Hidden Costs Should You Watch For?
Even with a clean per-minute model, there are costs that catch buyers off guard.
Telephony and number costs
If you use Bolti's own phone numbers, that's included. If you bring your own SIP trunk — Twilio, Plivo, Exotel — you'll pay that carrier's per-minute rate separately. For most Indian SMBs, Exotel or Plivo domestic rates run ₹0.50–₹1.50/min on top of the platform fee.
Provider API keys (if you self-supply)
Some platforms let you bring your own OpenAI or ElevenLabs keys, which means you pay those providers directly. This can lower your effective cost at high volume but adds billing complexity. Check whether the platform's base rate assumes bundled providers or not.
Language and accent support
Indian-language calls (Hindi, Tamil, Telugu, Marathi, Bengali, Gujarati) often require specialised STT models. Fennec and SarvamAI are built for Indian accents; global providers like Deepgram perform well on English but may struggle with regional languages. If you're running multilingual campaigns, confirm which STT provider is included at the quoted rate — or whether Indian-language support costs extra.
Volume discounts and enterprise contracts
Pay-as-you-go is convenient, but if you're running tens of thousands of minutes per month, a committed volume deal almost always works out cheaper. Most platforms — including Bolti — offer enterprise pricing for high-volume or white-label deployments.
How Does Bolti Compare to Alternatives?
The two platforms Indian buyers most frequently compare against Bolti are Bolna AI and Ringg AI. Here's an honest breakdown of what to look at:
| Factor | What to ask |
|---|---|
| Per-minute rate | Is it all-in or does it exclude telephony/LLM? |
| Free trial | How many minutes, and do real calls count? |
| Indian language support | Which STT providers are available for Hindi/Tamil/etc.? |
| Interruption handling | Can callers cut the agent off naturally mid-sentence? |
| Bring your own trunk | Can you use Exotel or Plivo to reduce telephony costs? |
| SLA and uptime | What's the guarantee for production call volumes? |
Bolti's ₹7/min rate includes sub-second turn-taking, real interruption handling, and telephony-grade noise cancellation — features that matter when you're running hundreds of calls a day on Indian mobile networks where line quality varies. The platform also supports BYOC (bring your own SIP trunk) so you can use Exotel or Plivo if you already have a preferred carrier relationship.
What's the Right Pricing Model for Your Use Case?
Different use cases have different cost profiles. Here's a quick guide:
- Outbound sales / lead qualification: Short calls (2–4 min), high volume. Pay-as-you-go works well. Prioritise low per-minute rate and reliable STT for your language.
- Customer support / helpdesk: Longer calls (5–10 min), variable volume. Consider whether a volume commitment saves money at your average monthly minutes.
- HR screening: Medium calls (8–15 min), burst demand during hiring cycles. A pay-as-you-go model avoids paying for idle capacity between hiring rounds. Bolti's HR screening agent is purpose-built for this — you upload CVs, and the agent calls candidates automatically.
- Payment reminders / appointment booking: Very short calls (1–2 min), high volume. Per-minute pricing scales linearly — run the numbers at your expected monthly volume before committing.

Frequently Asked Questions
How much does a voice AI phone agent cost in India?
Pricing varies by platform and model. Bolti charges ₹7 per minute, all-in, on a pay-as-you-go basis with no monthly minimum. At typical call volumes — say 2,000 calls averaging 4 minutes — that works out to roughly ₹56,000/month. Some platforms charge separately for telephony, STT, and LLM on top of a platform fee, so always check what's included.
Is there a free trial for voice AI agents in India?
Yes. Bolti offers a 50-minute free trial with no credit card required. The trial runs on real phone lines so you can test actual call quality, language support, and agent behaviour before committing any spend.
Do Indian-language calls cost more than English calls?
Not on Bolti's ₹7/min rate — the per-minute price is the same regardless of language. However, some platforms charge extra for specialised Indian-language STT providers like Fennec or SarvamAI. Always confirm whether your target language (Hindi, Tamil, Telugu, etc.) is included in the quoted rate.
Can I bring my own telephony provider to reduce costs?
Yes. Bolti supports BYOC (bring your own SIP trunk), so you can use Exotel, Plivo, or Twilio if you already have a carrier relationship with favourable per-minute rates. This lets you separate the platform cost from the telephony cost and optimise each independently.
What's the difference between pay-as-you-go and enterprise pricing for voice AI?
Pay-as-you-go (like Bolti's ₹7/min) charges only for minutes used — ideal for variable or unpredictable call volumes. Enterprise pricing typically involves a committed monthly volume in exchange for a lower per-minute rate, plus extras like SLAs, on-premises deployment, SSO, and white-label sub-accounts. If you're running more than ~30,000 minutes/month, a committed deal usually pays off.
