Voice AI Platform Pricing India: What ₹7/Min Actually Covers in 2026

Bolti Team·

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 (no card required), it's one of the most transparent pricing models in the Indian market. This post breaks down exactly what that ₹7/min covers, how it compares to alternatives, and how to calculate your real cost before you commit.

What does voice AI platform pricing in India actually look like?

Most Indian voice AI platforms charge somewhere between ₹5 and ₹20 per minute, but the headline rate rarely tells the whole story. Some platforms bill STT, LLM, and TTS separately on top of a base telephony rate. Others bundle everything but cap usage or charge for features like multilingual support, API access, or dedicated numbers.

Here's what the pricing landscape looks like in 2026:

Platform Pricing model What's included
Bolti ₹7/min, pay-as-you-go STT + LLM + TTS + telephony bundled; 80+ languages; API access; free trial (50 min, no card)
Bolna AI Varies by plan Separate provider costs may apply depending on configuration
Ringg AI Custom / quote-based Typically requires a sales conversation before pricing is disclosed
Vapi USD-denominated Billed in dollars; exchange-rate exposure for Indian teams; provider costs often pass-through

The two angles most competitor pages skip entirely: (1) whether the free trial actually requires a credit card, and (2) whether multilingual Indian-language support is included or an add-on. Bolti's 50-minute free trial requires no card, and Hindi, Tamil, Telugu, Marathi, Bengali, Gujarati, and 80+ other languages are available at the same ₹7/min rate.

What does ₹7/min include on Bolti?

Bolti's ₹7/min rate is an all-in number for a managed call. It covers:

  • Speech-to-Text (STT): Transcription of the caller's audio, including Indian-accent-optimised models (Fennec for Hindi, Tamil, Telugu, etc.) and global options like Deepgram and Azure
  • Large Language Model (LLM): The reasoning layer — GPT-4o family, Gemini 2 Flash/Pro, Groq Llama, DeepSeek — whichever you configure per agent
  • Text-to-Speech (TTS): Voice synthesis via Cartesia, ElevenLabs, SarvamAI (best-in-class for Indic languages), SmallestAI, or Inworld
  • Telephony: The actual phone call, whether inbound or outbound, via Bolti numbers or your own SIP trunk (Twilio, Plivo, Exotel)
  • Platform runtime: Sub-second turn-taking, interruption handling, telephony-grade noise cancellation, call recordings, transcripts, and the REST API

Nothing above is metered separately. You pay ₹7 for every minute a call is active, and that's the bill.

What's not in the per-minute rate

A few things are outside the per-minute charge:

  • Phone number rental: If you use a Bolti-provisioned number rather than your own SIP trunk, there's a monthly number fee (check Bolti's full pricing breakdown for current rates)
  • Enterprise add-ons: On-premises deployment, SSO via OIDC/SAML, PII redaction at runtime, sub-accounts for white-labelling, and DPDP/GDPR/HIPAA-aligned contracts are enterprise tier features
  • Your own provider API keys: If you bring your own OpenAI or ElevenLabs key to reduce cost further, those providers bill you directly

How does this compare to building your own stack?

Some teams consider assembling their own STT + LLM + TTS + telephony pipeline instead of using a platform. The math rarely favours DIY at early-to-mid volumes.

A rough cost breakdown for a self-built stack handling 1,000 minutes/month:

  • Deepgram STT: ~$0.0043/min × 1,000 = ~₹360
  • OpenAI GPT-4o: ~$0.005/min equivalent × 1,000 = ~₹420
  • ElevenLabs TTS: ~$0.006/min × 1,000 = ~₹500
  • Twilio telephony: ~$0.013/min × 1,000 = ~₹1,090
  • Engineering time to integrate, maintain, handle interruptions, noise cancellation: not zero

Total provider cost alone: ~₹2,370 for 1,000 minutes — roughly ₹2.37/min in raw API costs, before any engineering overhead. Add a developer's time to build and maintain the pipeline and the effective cost per minute climbs fast. Bolti at ₹7/min gives you a production-ready runtime, a managed dashboard, and ongoing provider updates included.

At 10,000 minutes/month (a modest outbound sales campaign), the difference between a working agent and a half-finished integration matters more than the per-minute delta.

How to estimate your monthly bill on Bolti

The formula is simple:

Monthly cost = total call minutes × ₹7

Some reference points:

  • 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 × 2 min avg = 20,000 min → ₹1,40,000/month

For context: a human outbound caller in India typically costs ₹20,000–₹35,000/month in salary, handles roughly 200–300 calls/day, and works 8 hours. A Bolti agent runs 24/7, handles concurrent calls, and scales to any volume without a hiring cycle.

If you're in healthcare, real estate, BFSI, or edtech — industries where appointment confirmation, lead qualification, and payment reminders run into thousands of calls per month — the economics shift significantly in favour of voice AI at this price point.

Which use cases get the most value per rupee?

Not all calls are equal. The highest ROI use cases on Bolti tend to be:

  • Outbound payment reminders: Short calls (1–2 min), high volume, measurable recovery rate. At ₹7–14 per call, the cost per rupee recovered is very low.
  • Appointment booking and confirmation: Clinics, salons, and service businesses running 50–200 bookings/day can automate the full confirmation-and-reschedule loop.
  • HR screening calls: Initial screening for high-volume hiring (BPO, logistics, retail) where a 3-minute structured call replaces a recruiter's time.
  • After-hours inbound support: Agents that handle FAQs and basic account queries when your human team is offline — every call resolved without a callback is a cost avoided.
  • Multilingual outbound sales: Reaching customers in Hindi, Tamil, Telugu, or Marathi without hiring language-specific agents.

Frequently Asked Questions

What does Bolti's ₹7/min pricing include?

Bolti's ₹7/min rate covers the full managed call: Speech-to-Text transcription, LLM reasoning (GPT-4o, Gemini, Groq, etc.), Text-to-Speech synthesis, telephony (inbound and outbound), call recordings, transcripts, and API access. Nothing is metered separately on top of that rate.

Does Bolti's free trial require a credit card?

No. Bolti's free trial gives you 50 minutes of live call time with no credit card required. You can run a real pilot — outbound reminders, appointment booking, or inbound support — before entering any payment details.

Is multilingual support (Hindi, Tamil, Telugu, etc.) included at the same ₹7/min rate?

Yes. Hindi, Tamil, Telugu, Marathi, Bengali, Gujarati, English, and 80+ other languages are all available at the standard ₹7/min rate. There's no language surcharge. Bolti uses Indian-accent-optimised STT providers like Fennec and SarvamAI for Indic languages.

How does Bolti's pricing compare to building your own voice AI stack?

Raw provider API costs for a DIY STT + LLM + TTS + telephony stack run roughly ₹2–2.50/min at low volumes, but that excludes engineering time to build interruption handling, noise cancellation, and ongoing maintenance. At moderate volumes (1,000–10,000 min/month), Bolti's ₹7/min all-in rate is typically more cost-effective once development and ops overhead are factored in.

Can I use my existing Twilio, Plivo, or Exotel account with Bolti?

Yes. Bolti supports BYOC (Bring Your Own Carrier) — you can connect your existing Twilio, Plivo, or Exotel SIP trunk, or use Bolti-provisioned numbers. Either way, the ₹7/min platform rate applies; your carrier charges you separately for the underlying telephony if you use your own trunk.
